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?

I will pull it tomorrow, any good carb cleaning guides on the site?
where do you guys recommend I get a gasket kit from?
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?
Well, it begins.... Took me awhile to get the carb kit and then a little bit longer to find the time, but its underway. I got the carb pulled in about 30 minutes and the bottom pan of the carb off, I stripped one screw out not realizing it but it turned out to be no big deal, just used a hacksaw to cut a notch then used a flat head screw driver.
