interpol timing marks
Anyone know if there are any timing marks that facilitate the use of a strobe to check the timing on a running engine .

Re: interpol timing marks
Sorry, there are none!
But, the vertical axis of the engine is the line between eccentric shaft and the bottom stud.
TDC is when the flywheel key is at either 9 o'clock to that line for the l/h rotor or 3 o'clock for the other.
Full advance timing, although not critical, is alleged to be at 18 BTDC, except for F1/F1 Sport fitted with a 'yellow-spot' flywheel
From that you should be able to mark your flywheel using a point on the casting as reference.
