I bought a banshee that doesn't run single carb set up but when I try to start it it will barely run like the timing is very retarded I pulled the stator cover off and when one of the pistons is at top dead center the pick up coil and the flywheel bit are about 25 degrees apart the flywheel being further ahead is that the way it is supposed to look please help me the cdi is good there is no tors stuff what could be wrong I need help thank you
