Ignition Timing
1. Attach a timing light to the #1 spark plug and mark the front crankshaft pulley timing notch. Locate the
timing pointer on the front gear case ant mark it as well (use a piece of soap, white chock, or white crayon
when making this mark).
2. Start the engine and warm it up to its normal operating temperature. Make sure the generator is operat-
ing without a load on it.
3. Using the timing light, align the timing groove in the front crankshaft pulley with the timing pointer. Do this
by loosening and slowly rotating the distributor body. Refer to the timing specifications below.

The electric choke uses a 12-Volt heating element which opens the choke automatically once the engine
starts and remains running. Some hunting will be present when the generator is started, is on choke, and is
running without a load on the generator.
IWARNINGI
To avoid burns on fingers or hands, DO NOTtouch the choke
housing while the engine is operating. Allow the engine to
cool before making choke adjustments.
Adjustthe choke by loosening the three cover-securing screws and
by rotating the cover clockwise to set the choke ENRICH and
counterclockwise to set the choke LEAN. The choke is initially set
at the factory.
