Give ya carby a good clean.

try lifting your choke up a little once you have it running and take off, if it runs better than what it did you need to change the needle height on the main jet. this is very simple, you just unscrew the cap at the top of the carby and move the little clip on the needle down, you will prob need to move it down about two knotches, if you are on your last notch and it still needs to run richer you will need a bigger jet.

What size motor do you have? if its a 140cc or 138cc a 102.5 main jet will work wonders. just pm me for any more questions

cheers
