This engine has a sticker on it that states:

MAX Advance timing is 23* BTDC @ 5500rpm. or 27* cranking speed of 300rpm.

However this engine cranks at 600 rpm. What would be the correct max advance ignition timing be cranking @ 600rpm?

"You have to time it with a li

"You have to time it with a light. I do mine by disconnecting the carb throttle linkage, then opening the throttle wide open. If the carbs don't open, it's not injurious to the motor.

PS: There's supposed to be a timing pointer located inside the cowl, along with the recoil rope. You stab it into the hole next to the timing tape."
