Hey guys, just rebuilt a carb that sat for a couple of years. The 2005 trx300ex fires right up with the choke on let her warm up, turn choke off and she dies. :-( this was my first carb rebuild so lord only knows what could've went wrong... Any suggestions as to possible problems and their solutions would be greatly appreciated. If it helps: when I turn the choke of and give it throttle it runs pretty rough with some pops coming from exhaust. Not really a back fire per se but popping. Let off the throttle and it dies pretty quickly. Put choke back on and she fires right up.
