If the fuel system is O.K. check as follows for ignition troubles.
FIRST: Be sure the ignition switch is turned to the "ON" position.
SECOND: Look for a fouled or broken spark plug.
THIRD: Check for weak spark. If a bright spark jumps across the gap between the two points of the plug
when the engine is turned over, the ignition system is undoubtedly in working order. This may be verified
by making the same test with each wire. The gap between the spark plug points should be approximately
.035" (or the thickness of a thin dime).
FOURTH: Check for a broken electrical circuit.
FIFTH: The cause may be due to a ground. Poor installation will cause a ground. Be sure all electrical
wires are clean and well insulated.
SIXTH: Poor contact at distributor breaker points.
SEVENTH: Distributor may be out of time.
TROUBLE SHOOTING
A gasoline engine depends upon three main factors for proper operation; an unfailing fuel supply,
uninterrupted ignition, and good compression. When any one of these are not present, or present only
intermittently, engine failure will result. The following "trouble shooting" information is designed to help
the operator locate and overcome some of the most probable causes of engine failure, or improper operation.
"Probable Causes" are listed in the most likely order of occurrence. Only one correction should be attempted
at a time and that possibility eliminated before going on to the next.
