I adjusted the valves, and ensured they were in spec after I was done. Had to remove the stator cover to get the cam chain back on the main drive shafe (lost the tension when the slack tensioner stopper slipped). Thus the piston had moved from TDC, but I realigned the marks on the crank shaft as well as on the cam sprocket, so the timing should be perfect, but it wont fire whatsoever. Is it possible to be off by a revolution of the sprocket, and thus the piston is on the wrong stroke thus causing the issue? I thought these 4-strokes fired at the top of every stroke, so that wouldn't matter. Any clues? Thanks in advance! Going to try a spark test today, but the spark plug was nice & dry, suggesting it was sparking, and the color was chocolate brown. I'm stumped.
