b. When the front cylinder piston is at TDC on
the compression stroke, align the TDC
mark "a" on the generator rotor with the slot

sion stroke, there should be clearance

tive rocker arm adjusting screws.
• If there is no clearance, rotate the crankshaft
counterclockwise one turn.
c. Measure the valve clearance with a thick-
ness gauge.
