Once again i would like to thank "LT80" for the help he offered on my carb. problem, I disassembled the carb. and found one of the passages on the front plugged, also when i installed the kit it showed an o-ring or seal under the main jet, i installed this o-ring with alot of difficulty then installed the main jet, I believe the o-ring was chocking off the main fuel supply, i removed it, cleaned the carb. reassembled and my son is on the trail again with a big smile on his face! I really appreciate the help!
