I'll mark the fan at TDC and put a strobe on it. It's a strange beast
in that it isn't piston ported and the carb is directly mounted on the
crankcase, reed valve I expect.

Dwell is important. This is the time volts are applied to the coil to
allow the flux to build up to the maximum, before they are interrupted and
the spark occurs.
