hi, just got into motorized biking, i love the concept and this site. ive looked on here for some help along the way. should have joined this site earlier because im in a mess of problems on my bike. i have skyhawk gt5 and its been a pain from the get go. first problem, I broke the screw flesh with the clutch arm. the clutch cable is really tight with no free play. anyways i ran into some problems with the garbage spark plug boot but i found an american replacement that seems to work very well. i cant start this thing no matter how hard a try. the engine is turning over and when i hold the spark plug to the fins and move the bike i see sparks. fuel is going to the carb. can lack of free play be the sole cause of not starting? I just grounded the engine on the rear mount, don't know if its a grounding issue. could it be the carb? can i get some solutions. should i try to remove this little screw, which might be impossible or go ahead and just buy a new clutch arm. this thing is really been a headache and im about to give up on it all together.
