ENGINE PERFORMANCE PROBLEMS
If your engine is running below its normal performance
level, you could check lor the following problems:
Check Compression: Remove spark plug and hold thumb
over spark plug hole while cranking engine Compression
should be sufficient to push thumb off the opening If
compression appears low, check for the following:
• Loose cylinder head bolts
» Blown head gasket
•
Worn or damaged engine
Contact Sears Service Center to repair these problems.
Check Carburetion: Make sure gas lank is filled with
clean, fresh gasoline. Make sure fuel shutoff valve is open.
Make sure fuel flows freely through fuel line between tank
and carburetor Crank engine several times, then remove
spark plug, If plug is wet, look for the following:
o Overchoking
o Rich fuel mixture
» Water in fuel
» Intake valve stuck open
If plug is dry, look for the following;
* Leaking carburetor gaskets
o Gummy or dirty carburetor
•
intake valve stuck closed

HOL-BLENDED FUELS (CALLED GASOHOL OR USING
ETHANOL OR METHANOL) CAN ATTRACT MOISTURE
WHICH LEADS TO SEPARATION AND FORMATION OF
ACIDS DURING STORAGE, ACIDIC GAS CAN DAMAGE
THE FUEL SYSTEM OF AN ENGINE WHILE IN STOR­
AGE TO AVOID ENGINE PROBLEMS WHEN USING
GASOHOL, THE FUEL SYSTEM SHOULD BE EMPTIED
BEFORE STORAGE PERIODS OF 30 DAYS OR
LONGER DRAIN THE GAS TANK, START THE ENGINE
AND LET IT RUN UNTIL THE FUEL LINES AND CARBU­
RETOR ARE EMPTY. USE FRESH FUEL NEXT SEA­
