Troubleshooting Guide
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.
Replacing the reed valve:
– Loosen carb screws and remove the carburetor (be careful to
not damage the gasket)
– Loosen four M4 screws on the flange, remove the flange and
take off the reed valve (be careful to not damage the gasket)
– Loosen four M2 screws and remove the old valves, replace
them with new ones, replace all screws and tighten gently
– Be sure the gaskets are in their proper places.
