[110rider]

well i got the 300 x running and now when i get on the throttle hard it spits and sputters. could this be from a little moisture in the carb or a head gasket i did notice a like smoke when i start it coming out the left side of the head towards where the top head gasket is
what do you guy think it is

Is it old gas? did you jet it right? Need more info.

[xman23]

sounds like its jetted to rich, is your carb dirty?

[110rider]

well i had a friend of mine who knows a whole lot about atc/atv and he soaked and cleaned the carb for me and the jets would be the stock jets theres no mods so i should be ok for the stock jets also no the gas is brand new

put the needle in the 2nd position-
it might have water in the fuel-
mine is a big main so i know what my problem is- hope this helps

we were hoping it wouldnt be the head gasket but its starting to sound like it is more and more and im thinkin it just the top one but shoud i just replace both?
