trx300 4x4 dies when throttle is pressed.

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.
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.
LOL I rebuilt mine sitting on the couch watching tv. The cab is for other pleasures.
Man you cant hide nothing from you guys.LOL
Starting fluid helps kill the bugs
