Makes me wonder if the carb is too large or small or even jetted properly. A picture of the sparkplug may also be helpful. Can you check the compression and post the reading?

 

i have a 2001 300 with the same problem its currently at the dealer getting the work done soon as i get it back i will let you know what they said my quad wouldnt start with the electric starter but you could pull start it and it should like what your quad is doing

 

This thread moved to the ATV - Mule section. We have really sharp members in there that may be able to help.

 

An Aftermarket carb might not be exacly setup for your bike.. most carbs out of the box are not "ready to go" . You might have to get fimilar with you bike, ake the carb off and on is not a huge task. 1st time migth take awhile but you will get better at the more you take it off (trust me you will)..
you say it sat idle. did you change the filters and fluids? did you check the gas tank make sure it's not full of rust or who knows what?..
Chances are you carb is not setup up properly,, I suggest you get to knwo what the settings are and how to adjust them. 1 thing I have learned with these bikes if hey don't start within the 10-20 seconds they aren't.
you'll need to dig deeper

 

im with nate on that comp test if it sat it could have siezed the pistons into there lands nad not sealing against the wall of the cylinder.

as for pull starting are you refering to being pulled behind a car/truck etc?

and you may also have to adjust the air mix screw for your alitutide levels

just a thoght but id do a comp test right off the bat to eliminate that as a prob.-corey-

 

If it doesn't start back up next time...

There are four things to make an engine run: fuel, air, spark, and compression. Take one away, the motor won't run.

Check for spark at the plug by removing the plug from the head and grounding it to the block. Use the pull start and see if the plug is firing.

A compression gauge is the best way to check for compression, but there are a couple of "*******" way to checking it (I'm a ******* so I can say that-actually I'm more of a hill-billy). Search for "compression" on this forum for different ways.

Fuel must make it into the cylinder, so it has to go from the tank, through the petcock, into the carb bowl, up the jets, and into the venturi tube. From the ventrui tube, it gets mixed with air going into the intake tube, and past the intake valve, and into the cylinder.

Air is simple. Check the air filter. Check for leaks around the hose connections. Leaks=messed up air/fuel ratio (stoichometery -I think I spelled that right).

 

hey tim that sure is a mighty big word (stoichometery ) us hill billys dont use em type words i cant even spell dat there word lmao.-corey-

 

I grew up in North Carolina going to public schools. We learned three things in school:

1. How to make the best darn sour mash whiskey in a homemade still.
2. How to shoot a side by side 10 gauge shot gun.
3. Everything about how to work on cars. NASCAR teams were all around my home town, so they figured that the children at NC schools would be working there instead of going and doing more important things like college.

 

Chad, I would go with Tim's first thread. It can only be a certain few things that not make one run properly. Like he stated air, fuel, and spark. If you could I would try to go back to the original carb to see if it could be rebuilt. the kits are cheap and that would eliminate the possible carb problem. If that doesn't work, then its time to look deeper, such as valve seals, carbon deposits on the valves, and even compression checks. If you plan on going about this by yourself vs. a dealer, I would suggest a Clymer manual. They are invaluable and give plenty of helpful pics and tips. Good Luck, let us know what you find out. Maybe we can help further.

 

tim lol.....we tennesse folk in my family and kentucky a true hillbilly lol-corey-

as for the no run bike the first thing i learned was to see if you have fuel goin to the carb have a spark and then comp.....but in this case of settin for a while i would reverse that .comp first,spark,then fuel. cause the rings can get stuck in ward and not seal.just a thought -corey-

corey and I make a great team, we think alike :shock: .....something else to check since it has been sitting...take a close look at wires, cracked insulation will short a wire to ground and cause similar probs.

 

i had the same problem with my 01 i took it to the dealer and from what they are telling me i have a stuck valve they in my case think its the intake valve and want about 500 to fix it im hoping to post on here and try to save myself some money plus im looking to get a book for it

chuck

 

ccbayou... if your valve is stuck shut you can take off the inspection cover to the valves and spray sum pb blaster on em let it set for a day then come back out the with a small ball peen hammer and a regualr hammer.take the wooden part of the ball peen put it on the rocker arm where you adjust the valve and take the other hammer and lightly tap the top of the ball peen and that will push the valve open of its rust spot then spary it again with pb blaster and try to start it.

if it runs let it warm up with out revin it up change the oil and filter. then let it run to warm it up again no revin .....shut it down let it cool off.then go out on a test ride but dont beat it for the first day let that oil do it job and lube the valve and guide back up good. hope this may help out -corey-

 

I have a kawasaki bayou 300 model klf 300b and I relaced the carburetor with a new one. When I try to start it gas comes out the throat to the air filter and in the filter box, What could be the problem?

 

In order to answer that, we would have to know why you replaced the carb in the first place.
Also is it an OEM exact fit carb?
