carburetor cleaner.

3. Thoroughly dry the filter and re-install.
*CLEAN THE ENGINE NECK
CAUTION
EXTREME CARE MUST BE TAKEN TO PREVENT DAMAGING THE GLOW COIL IN THE
COMBUSTION CHAMBER. ANY TOOL USED SHOULD BE SHORT ENOUGH TO PREVENT THE
TIP OF THE TOOL FROM REACHING AND DAMAGING THE GLOW COIL.
A DAMAGED OR OUT OF POSITION GLOW COIL WILL CAUSE POOR ENGINE STARTING AND
OPERATION.
ACCUMULATION OF CARBON IN THE ENGINE NECK WILL ULTIMATELY RESULT IN HARD
STARTING AND POOR PERFORMANCE.
*EXAMINE THE SPARK PLUG
In general, the only time the spark plug goes bad is if the white porcelain becomes cracked or broken.
Occasionally carbon will form on the electrodes. When this happens, rub the carbon off with a piece of steel
wool. The spark plug is gapped at 0.060” or slightly less than the thickness of a United States nickel. Always
install the spark plug with your fingers. NEVER USE A WRENCH TO TIGHTEN THE SPARK PLUG.
*ADJUST THE ON-OFF CONTROL
1. If the On-Off Control linkage does not rotate the linkage stop from full open to full closed, (see
figure 7), then the linkage should be adjusted.
2. To adjust the linkage, loosen the Jam Nut and twist the Control Wire into the Control Linkage in the
direction needed. When properly functioning, the On-Off Control should rotate the Linkage Plate as afar as it
will go in either direction.
