manual-start type plants with magneto igni-
tion as for remote-start type plants with 12 volt battery ignition.

before top center for all models with engine
speeds ranging from 1500 to 2400 rpm. Models with engine speeds of
2500 rpm and up use the 25

Remove the cover from the breaker box. If the timing is very far
off, attain an approximate setting by loosening the mounting screws
and shifting the breaker box (and spacer if used) to align the witness
marks on the cylinder block and breaker box (or spacer).
2. Crank the engine over slowly by hand in the direction of crankshaft
rotation until the witness mark on the flywheel and the "TC-" mark
. on the gear cover ar e exactly in line. See the illustration Ignition Tim-
ing.b
3. Adjust the ignition breaker point gao width to 0.020 inch at full sep-
aration.
