ill start from the beginning. a while back i had to replace crank seals on the flywheel side i put the quad up against a wall and tightened the nut on the flywheel with some channel locks and leaving it in gear so it wasnt very tight. the other day my quad was running terrible like idle to 1/4 throttle was great, but from there it would bog hard until full throttle. i kept messing with it and nothing unil it completely died. turns out a reed flew off and half of my gas was comopletely bad and seperated. so i got new reeds and put em in yesterday and it started but was idling really low and when i hit the throttle it bogged and died and would not start again. it occassionally would try to start and spit and backfire and blow me off the kicker but there was no signs of life. i KNOW its not the carb because it is clean as ever and has new gad and the floats are set right. its not the reeds bacause i just got them. i have great compression and spark but the spark looked a little inconsistent. i have a good feeling only thing left is that flywheel key would that cause these issues?
