If the engine does not start
- check and use a new spark plug if needed.
(Check the spark: Put the plug into the cable end and by turning
the engine you’ll see the necessary spark. Note: The plug must
touch a metal part of the engine.)
- check fuel lines.
- check for proper mechanical function by turning the
engine over.
- check that the carburetor is correctly installed.
- remove the carburetor cover from the feed side; check
the filter and blow off carburetor with compressed air
( Caution: When using compressed air, use eye protection.);
when re-assembling be careful to maintain the proper order of
the components.
- check the vacuum feed line.
Mechanical Faults
If the engine can not be turned over easily
- a likely cause is the piston in the cylinder is seized: loosen
and unscrew the cylinder bolts.
- carefully remove the cylinder.
- visually examine the piston and crankcase to find the likely
cause of the engine’s mechanical problem.
Note: Mechanical repairs must always be completed by a
professional service department.
