I inherited this ATV a few months ago. It has been sitting for maybe 2 years. it started right up. It only runs with the choke on. I drained the old gas and cleaned the tank. took the carb out and cleaned it and gave it a carb soak. Noticed it had no gaskets so I ordered a refurbish kit. Just in case I ordered a new Chinese replacement carb also. I put the old carb after rebuild on the shelf for emergency. I installed the new carb and it fired right up. My only issue is the idle is way to high and the throttle adjustment on the outside of the carb is all the way out. for the record also I was told the last time it was ran it fell out of the truck going down the road and the handle bars are tweaked pretty hard so i got a solid used perfect match and switched those out also. It is amazing how little outward damage it took! So far everything is working perfectly and everything is straight. Is there another throttle adjustment that can be done with out tearing everything apart again?

Thanks all!

The only adjustment you can make on china carbs that will fix your motor is a quick toss into your trash basket. You'll need to put your OEM carb on the motor to fix it.

Use the service manual to set up your OEM carb to specs. Use only the rubber gaskets and o-rings from cheap china carb kits in your OEM carb. The brass jets, all metal parts, and the float valve in china kits are pure garbage. Your OEM carb has to have all OEM hard parts in it, or it won't ever work right.

I'm with retro. Not much cure for knock off parts. I know pain of buying a new carb and all. But I would've worked on that carb as much as you can before buying a new one. Put old carb on and let us know what happens and we'll help you out

I'm with Retro and Johnny. Buy a new carb.

No... don't buy a new carb, fix the original. They are easy to clean up and setup to specs.

Me and retro don't think you should buy new carb haha. Put old one on and let's fix it

When you are putting your old carb back on, be absolutely sure that you get a total seal between the carb and boot, and the boot and cylinder head. If the old boot is stiff, replace it. If any air leaks in there, it will give you a fast idle, and that could be part of your problem.

Chinese carb is working great now. I took it back off and opened the throttle cover and saw the problem right away. Throttle cable was not seated correctly in the grove. Adjusted the cable, put the carb back on, started it, adjusted idle screw and runs like a champ. The OEM carb has parts on the way. When it is back in action it is going back on!

Thanks for the help.
