Another one back from the dead (1997 King Quad 300 LT-FWDX)

By Hagbard

Gotta love Facebook Marketplace, and the crackheads that you can buy things from on there... 

Naturally, I'm like "Hook up the trailer, let's go get this pile of eBay parts!" and hauled ass to this dude's house with 3 crisp Benjamins to wave under his nose. Showed up about 20 minutes early to find him and his buddy hastily reassembling the pile of plastics into a semi-presentable quad, using some real sweet bulk bin galvanized hex bolts from Tractor Supply Racing Co.
Looked it over and handed him the three bills in exchange for a transferrable registration from 11 years ago, and a STACK of handwritten bills of sale from the last 11 years, since apparently no one has gotten it functional (for long). Average ownership period ranges from 6 months to 2 years. Fingers crossed, lads!


Got it home, and hit it with a healthy dose of bike wash and the pressure washer, more bike wash, a lot of scrubbing, and more pressure washing to get years worth of crud off of it. The entire left side of the crankcase was covered in an eighth inch of caked oil mud, as though there had been a catastrophic loss of oil at some point in the past, because it was nowhere near the drain or fill holes. Totally opposite side. Managed to find the VIN hiding in there and ran it for giggles.


PO mentioned that he "had it running at the beginning of the season, but it was 'rough' " and that he had cleaned the carb, but it didn't help much. And now it just plain wouldn't fire at all. Kind of threw his hands up and shrugged.  So, after cleaning it up enough to turn wrenches without looking like a Texas oilman, I took off the plastics and started poking around. Found a few fishy spots in the harness where previous attempts at repairs had been shoddily made and hidden with black tape. Sorted those out, drained and filled with fresh oil and a filter, and hooked up a battery. Turned the key, got a green light, hit the starter switch and got a little grunt and squeak out of it, then nada. No light, no nothing. Pulled out the DeOxIt D5 and started pulling apart all the connectors and giving them the business. put everything back together again, turned the key, got green light, and starter cranked! Then nothing again. Started fiddling with the wiring and connections while watching the green light, and saw a flicker when I bumped the 25A fuse holder. Gave it a squeeze, and sure enough, the light came on. Thing was full of powdered remains of spade terminals, so I installed a NOS replacement model from RADIO SHACK that had been swimming around in my toolbox for nigh a decade. Sure of my fix, I tried the starter again, and NOTHING again. More fiddling revealed that the OTHER fuse holder (15A) was the same. Homebrewed another fuse holder from spade connectors and shrink tubing, hooked it all up and everything was good.

Now that I could crank it, I poured a couple cups of gas in the tank and pulled the plug to check for spark. Good blue spark, once I cleaned up the theretofore fouled plug and gapped it. Screwed it back in, with a healthy dose of ether, and gave it a crank. Not even a wheeze or a sputter. Off with the carb!



So, I think our old friend PO has a drastically different definition of "carb cleaning" than I do. I'm thinking maybe he wiped down the OUTSIDE of the thing, and was shocked that it had little to no result. That white stuff is a combination of powdered aluminum oxide and near-varnish fuel. Has the consistency of slight dried mayonnaise or white library paste, but no pleasant wintergreen aroma to match.   A quick perusal of the Amazon bargain bin turned up a carb (BST31SS) and non-vacuum petcock for $25, with a caveat that the carb required minor modifications to fit. Four days and a lot of sandblasting and surface prep on the plastics while I waited, the carb arrived today and I drilled out the ferrules for the choke and throttle cables to accept slip-fit cables instead of thread-ins. Other than that, the only difference was a lack of one vacuum port for the petcock, which I had anticipated and purchased a regular old one with no vac diaphragm in it. Safety first, amirite?

Now with definite spark, and reliable fuel delivery, I started cranking and fiddling with the idle and air screws, managed to get it to fire up - almost literally~ There was a LOT of smoke coming from near the exhaust port on the head, thought I had loose header studs for a minute, then realized it was just more of the old oil mud I had missed while cleaning, burning off between the fins on the head and the exhaust heat shield.

First fire up - lots of smoke

While I was changing the oil, I took the opportunity to pull off the access covers and adjust the clutch and valve lash, so I was feeling OK about running it a little more. Got the idle and mixture set a bit better and decided to test out the transmission and shifting a little.

Testing reverse

Realized I left the parking brake set, so it stalled out. Oops.  Another thing I did while waiting for Brown Suit Santa to bring my carb was to remove the diff lockout pin from the shifting mechanism and I wanted to see if it worked. Here's the quad, up on the lift, minus the LF wheel (due to a seized cylinder I've since replaced) with range set to HIGH, and Differential Lock engaged. Worked like a charm. Had to holler at the dog who was camped out below the rear tire  Dog under the tire. Again. I think she has a death wish. Or perhaps aspirations of being a jackstand in the pro-leagues.

Testing Diff Lock in High Range

Put the wheel cylinder in, (Dorman w38750 for a 1991 Geo Metro/Suzuki Swift was a precise fit and only $10) to replace this crusty POS:


put the wheel and hub back together, put seat back on and fired it up. Made sure it would start again after turning it off.

Long Live The King

All the repairs appear to have been successful all around! I took it out for a quick rip up the street and back, needs a little bigger main jet (it came with a 145 installed, which I swapped out for the 120 OEM spec, but it feels boggy at WOT, so I'm going to experiment a little after I get the airbox back together, but 145 seems like a big jump.

I'll try to post an update once I have the plastics all refinished and installed next week. Pretty sure it's going to be yellow, no camo or green bullshit for me thanks   Hope you didn't hate my post.

If your ATV engine is not getting enough fuel, it won’t run properly. You’ll notice it bogging down and just not having the power it used too. If you’re not getting fuel to the engine at all, it won’t even start for you.

The most common reason an ATV engine is not getting fuel usually has to do with the carburetor. Either a stuck needle valve or a loose or cracked vacuum hose are the most common issues. Don’t worry, there are pretty straight forward things you can do to check where your problem is.

There are a few different reasons you may not be getting fuel to your engine. It’s not that hard to check the parts to see if their working properly. I recommend going step by step checking one thing at a time, eliminating possible issues as you go.

If you have a fuel injected engine, you can skip this next part and jump straight to the fuel injectors, fuel pump, and compression check sections.

Check The Carburetor

I would first check the carburetor to help narrow down where you should start your investigation. All you need to do is spray a little carb cleaner or ether down the carb and see if your engine will fire up with that. Or you could pour a little gas in the carb and try to start it up.

If it does start, and then dies right away, at least we know now it’s a problem getting fuel to the carb. We know that now because, when the carb has fuel, the engine will run. You should check to make sure fuel is getting to the carb now.

If it still doesn’t start at all, you may have a problem getting fuel from the carb to the engine. That is telling us the problem is further down the line. It could be an issue with compression if that’s the case.The engine doesn’t have enough compression to pull in the fuel it needs and stay running. I will go over how to do a compression check later in this article.

Another check to do with the carburetor is to adjust the idle mixture screw. I know it sounds too good to be true, but a lot of times this adjustment isn’t set right so the engine isn’t getting the right air/fuel mixture to run properly.

Is The Carb Getting Fuel?

Ok, you sprayed something into the carb and the engine started up for a few seconds. Great, now we need to make sure the carb is getting the fuel it needs for the engine to run. Disconnect the fuel line going into the carb and put that end into a bucket or something to catch the fuel.

You may need to take out any spark plug, or just unplug them, just in case. And try to start the engine and look to see if fuel is coming out of that fuel line. If there is, then you have no problems getting fuel from the gas tank and it is probably a needle valve or float problem.

If there’s no fuel coming from the tank down that fuel line, then you’re problem may be an issue with the fuel pump, if you have one, or an obstruction in the fuel line or shut off valve. I will go over how to diagnose the fuel pump later in this article.

Needle Valve And Float

If the needle valve in your carb is corroded, it will not allow fuel to flow to the engine properly. Same thing will happen if your float is getting stuck. You’re going to need to clean the carburetor and possibly replace those parts if they’ve gone bad.

First remove the float bowl to gain access to the carburetor insides. Then you can remove the pin holding the float in place. Before you do that, you can try moving the float up and down with your hands, the float should move freely and have no resistance feeling when moving it.

The needle valve will be attached to the under side of the float, here is a picture of what you’re looking for. You can try cleaning the needle valve using carb cleaner. Just soak the thing and let it sit in carb cleaner for a few hours.

If that didn’t help, or you just don’t want to do it, no big deal. Needle valve are pretty cheap online. Here’s an example of a Carburetor Float Valve Needle on Amazon to give you an idea of what you’re looking for.

Or check out LionParts for a more specialized parts dealer.

You can also replace the float if you want to, usually you don’t have to but i would give it a good cleaning. Double check all the seals and everything since you’ve got the carb open, and clean out everything really good.

Check the bowl gasket, if this was bad, you would have noticed the carb leaking fuel before. To check and replace the valve seal, you’ll need a pick or something to pull it from the carburetor. I’ve used a sheet rock screw before. Just thread the screw in a little and pull out the seal.

Check out the picture for an idea of what you’re looking at. Once you’ve removed the old seal, insert the new one and make sure it’s seated all the way.

You can do that with a metal punch or something, just make sure you don’t hit too hard because you could break the aluminum frame of the carb. Reassemble with new needle valve and you should be good to go.

Check Fuel Injectors

Fuel injectors can get gummed up after a while if they aren’t cleaned regularly. The end of the fuel injector has small holes in it that the fuel passes through, creating a spray that enters the cylinder. If those holes get gummed up, the spray will be off, and you’re engine won’t run.

If you think it could be a problem with your fuel injector, I’d recommend trying to clean them first before buying new ones because they can be pretty expensive. First, you’ll have to remove the fuel lines that hook to the fuel injectors.

You could always remove the fuel injectors completely and let them soak in some fuel injector cleaner. I use this B-12 Chemtool Thru-Rail Fuel Injector Cleaner but you can use any carb cleaner / fuel injector cleaner you want to.

If you don’t want to remove the fuel injectors completely you can try another method. You will still need to remove the fuel lines and let all the gas drain out of them. You will then fill the fuel line with fuel injector cleaner, and then reconnect the fuel lines.

Try starting the engine for at least 20 seconds. If it does start, don’t let it run for longer than 20 seconds. Then you want to sit and wait about 10 minutes or so. You need to give the fuel injector cleaner time to do its work. Repeat the process five more times, but only try to start for 10 seconds, and then let sit for ten minutes.

I know it’s not the official way to clean the injectors, but I’ve seen it work, and it can save you from all the work of removing the injectors. Once you get the quad running, you’re going to want to add a fuel additive to your gas to keep the injectors clean.

You should be doing this at least once a year anyway. I do it with my maintenance checks before spring begins every year. I usually just add some of this Gumout Complete Fuel System Cleaner to the gas tank before I start it up for the season.

If you do need fuel injectors, Try LionParts, they can usually be found online for most ATVs.

Is The Fuel Pump Working?

I would say to try blowing air through the fuel pump to make sure fuel will be able to flow freely through it. But if you have a vacuum operated pump, you won’t be able to do that. There are diaphragms in there that could get damaged.

To make sure you’re vacuum operated fuel pump is working correctly, pull the vacuum line to the fuel pump off and crank the engine. You should feel a good amount of suction at the mouth of the carb.

The engine crates a vacuum pulse to the fuel pump, which in turn creates an amount of pressure that pushes fuel into the carburetor. If you’re not getting good suction, try replacing the diaphragms in your fuel pump and make sure your vacuum lines aren’t cracked.

If you can, try cleaning the fuel line out and replacing the fuel filter to make sure you’re getting fuel to the carburetor. Inspect the fuel pump for wear and loose or cracked hoses. If there is no vacuum in the hose, you’re carb won’t get any fuel. This is most likely caused by a crack in the vacuum fuel lines or a bad fuel pump.

You may find it easier to just replace the fuel pump all together since they aren’t usually very expensive. I like to use a store that specializes in ATV parts like LionParts for things like this. They have free shipping, and you can usually find what you need there.

Compression Check

The compression check is pretty straight forward, you’re trying to see if you’re engine can handle the right compression to run properly. Without compression, you won’t get fuel and your ATV won’t start.

The steps are pretty simple if you have a compression tester kit. Basically, you remove the spark plug, hook up the compression tester and run the test. You just have to make sure your engine is at the down stroke in the compression cycle.

I go over this process in a lot more detail and explain step by step how to perform this test in my article, Top 7 Reasons An ATV Smells Like Burning Oil. If you weren’t getting good compression, but enough that the quad still ran, you would leak oil into the cylinder. Go to that article and scroll down to the leak down test section for a step by step guide on checking for compression.

Problem Suzuki Quadrunner petcock

depending on model

Loosen your gastank cap and see if gas will flow through line before it reaches petcock.
If so your tank and gas cap/vent is OK.
If you have cleaned petcock and carb cleaner flows through easily.
Then your petcock is OK.
Then take off gas line at the NEXT connection, either the carb or a fuel pump.
It is probably connected to the carb on many QuadR 4wheelers.
If gas flows freely from there, your problem is most likely in the carb.
Take carb bowl off and clean, making sure your float will allow gas to flow out with bowl removed, and stopped when you lift float upward.
Good Luck, hope it helps.
PM me if I can help, I fought a cold-natured kick-start only 1984 Quad for 4 years in a row.:bangingheFinally unloaded it dirt cheap, and the guy that bought it has had no problems out of it:banginghe

Suzuki Quadrunner 250 Carburetor Hack, Junk Mikuni Swap to PZ30 Clone!

Andy somehow shoved his cock into my mouth. I grabbed his ass and began to push his cock deeper into my mouth. Andy hummed louder and began to cum. I almost choked on this endless stream of Negro sperm.

Having said this, she asked me to pull off her panties as they squeeze her and she is uncomfortable. I pulled off her panties and she lay on her side. I began to rub her painful left thigh and her ass. She lifted her leg to make sure that it was easier for her. When she lifted her leg, I had the opportunity to once again make out her cunt, neatly overgrown with hair, neatly trimmed and trimmed and leaving a place at the entrance.

Suzuki King Quad 300 Project - Part 2 - Fuel delivery

Why we met, we somehow quickly agreed to meet at their apartment on the next weekend. And now we are already at their place, sitting at the table to relieve the stiffness and awkwardness, after all, this is. The first time for them and for us, we decided to have a drink. After several small glasses, the stiffness became much less, we switched to the topic because of which we met.

Of course, they put on light music and I invited Ira, Igor Luda to dance.
