I have a GV400 on a Deiutscher mower which has given great service, but which now will not fire up at all. There is suction at inlet port. Both valves are functioning. Spark seems to be intermittent, and weak. I think maladjusted points must be the problem??, but cannot remove flywheel. Is the nut holding this flywheel right or left-hand thread? Wheel rotates clockwise. I cannot find a serial number, so am not sure of this points and condenser or not. Suggestions please.
