I got a 94 TRX300 4x4 on trade a few weeks ago and I seem to be having some issues with it. Its in good shape and not ragged out like most. It has a home made snorkel, 2" I think, and seems to have issues with running rich. I replaced the plug and the start solinoid for the choke and it help and ran good til I fouled the plug out again. It blows a little black smoke when you give it gas and spits and sputters. As long as you keep it around 1/4 or better it runs like a champ but under that it sputters and stalls. I am also getting a little fuel in the filter box. It will not idle either. I had planed on rebuilding the carb and putting the stock snorkel back on but I wanted some expert takes on it. I will use it for hunting only so I have no need for a snorkel.
What do yall think?
