360 driveability problem

not necessarily. the "A"dvance and "R"etard is for changing when the powerband comes in. retarding it brings it in sooner. advancing , later. did the dot at 12 o'clock on the bottom sprocket line up with the dot at 6 o'clock on the top sprocket? if worn , your in there.....

when you have it back together, what is total timing? 35 btdc? what rpm? what color are the plugs?
