STARTING THE ENGINE
CAUTION: Before starting the engine, be sure all tools, wires
and miscellaneous objects are clear of moving engine parts.
1. Connect a timing light. Find the area with the best view of the
timing marks.
2. Crank the engine. If it fails to start, rotate the distributor in small
increments left or right until engine starts. Do not exceed more
than ten degrees of rotation either way.
3. Set timing as recommended by the engine manufacturer, then
tighten the distributor hold down clamp. Make sure timing is still
correct. If timing has moved, repeat this procedure.
