I have a kazuma 250 and it sat all winter. I cleaned carb, starts great but when i give it gas it dies out everytime. I tried adjusting the carb fuel screw wih no luck. I loosened it till it was rattling.

Please help, i'm getting frustrated with this thing.

 

What type carb is it? a CV type with the slide pulled up by a diaphram, or a slide type with an accelerator pump? If a CV carb, look for a hole or tear in the diaphram, that can cause the slide to be sluggish or not rise at all, giving you a bad stumble. If it has an accel pump, and it is stuck or gummed up, lacking that shot of fuel will stall it out when you hit the throttle.

 

Not sure what type of carb it is. Its a kazuma 150 falcon. Would it be best to get a new one.

 

carbs aren't cheap, taking it apart and checking it out is free, just costs a little of your time, if you dont feel comfortable taking it apart, see if a buddy will help you, or take it to a small engine shop that you trust, and see if they can look it over.

 

I have taken it apart a few times. Nothing looks wrong, i think its just i need to adjust but dont know what or how to adjust

 

Explain how you took it apart and cleaned it, please. Did you take all the jets out and spray carb cleaner through them? Sounds like you have a clogged main jet.

Edit: You most likely have a CV carb. Those are fairly standard on the 150cc GY6 chinese quads. Pretty reliable carb for the most part.

 

I took the carb off unscrewed every screw and jet, sprayed carb cleaner into every hole, crevice, etc. soaked bowl, ran a small wire thru jets, snugged them back into and put it wll back together.

I guess it would not hurt to double check the jets again, i might do that just to be safe.

Any ideas

 

Sounds like you cleaned it right. Hmmm. Like someone else mentioned, if the diaphram has a hole in it, it would not pull up upon giving it throttle. Make sure the needle up there is moving up with the diaphram.

 

How do i make sure it is moving

 

I would just make sure that the slide and needle move freely in there. The diaphram should raise up, pulling up the slide, which in turn pulls up the needle. Take the top of the carb off and make sure there are no obstructions and that you can manually lift the slide/needle.

Take care when you put it back together as the diaphram needs to seal well to work right.
