I have a 99 fourtrax that has been sitting for awhile that I am having problems with. If I choke the quad I can get it to start, but it will die once I unchoke it no matter how long I let it warm up. In neutral, slightly choked it will continue to run. Once I put it in gear it will run (stil choked), but dies once I give it any throttle.

the carb is the obvious suspect, but thought I would get some suggestions before tearing in to it. Also reading the forums I see some suggestions of sea foam, should I try adding some to the tank and letting the bike run idle for awhile or start in a different direction?

Welcome to the forums. The carb its self is simple. Just have a clean and clear area to work Have something to clean the jets out like a peace of wire brush or torch tip cleaner.

trx300 w/the choke issue

I agree with the others on the carb cleaning.
But i would recomend getting a Gasket kit for the carb while your in it.
I had a 300ex doing pretymuch the same thing and i had to do it twice because the old gaskets were leaking air by and also weeping gas out a bit.

Thanks for the suggestion, Having never rebuilt a carb should it be pretty self explanatory once I get it open? Just replace the old parts with the new ones in the kit? Will I need any specialty tools?

Most are pretty simple. Just watch what you are doing and have a clean area to work on so not to loose parts and keep dirt out. Be sure to clean the cab out also.
