My brother just bought a lt50, 2stroke, for my nephew and we took it out for a spin and it had NO balls. My 40lb nephew was on it and it would bogg when reved and go nowhere. I took the carb apart and found that the float was stuck in the down position and the main jet was clogged. Now the bike revs fine when the rear wheels are lifted off the ground but when my nephew gets on it has trouble taking off still. If i give it a push it takes off and jams pretty fast so its just that low end it has trouble with.
If you guys have any ideas what it could be, please let me know.
Air filter has been cleaned, Old 2cycle drained and replaced with yamalube2r, gas is fresh 91, and the carb is completely clean.
******Where can i buy jets for this bike????
