    There is only one timing option and that is as you have indicated unless you happen to have a sheared flywheel key. Improper air gap between flywheel and coil can affect timing but if you are in the area of .010" you will be alright. Do you have good spark at the plugs? You might want to check your valve adjustments as well.

    I'd Bet valves, Make sure the piston is 1/4" down the cylinder past TDC compression stroke and adjust at .005-.007" both intake and exhaust.
