General Inspection
Once the engine is removed from the equipment, this is an ideal time to inspect for damage as well as potential
areas that may require repair. Some of the diagnostic evaluation cannot be effectively performed after
disassembly has begun.
Cover, Shroud, Fan Case
Inspect covers, shrouds, and fan case to identify damage or cracks due to
vibration, ground contact, etc. All of the shroud components are designed for
routing the flow of cooling air around the engine. Any broken or missing
components could lead to over heating of the engine during operation. Order
replacements as need.
Inspect the rubber spark plug boot for any damage that may cause a potential
shock hazard.
Ensure that the fuel tank is not damaged in any way due to possible ground
contact, excessive vibration, etc.
Any potential fuel leaks may be apparent during this initial inspection, as the
exposed fuel on the engine components may attract dirt. This provides a good
visual reference.
Recoil Starter
Ensure that the engine turns freely when the recoil starter is pulled, and
that the recoil starter rope retracts positively into the starter housing.
Fuel
If gasoline is present in the fuel tank, take the opportunity to empty it
into a clear container. This may reveal contamination such as water,
(as depicted in the photo – phase separation of gasoline and water is
very obvious), sediment, or the lack of two-cycle oil/fuel mixture.
Air Cleaner
Remove the air cleaner cover (A), and inspect the air cleaner element
(D). Ensure that it is clean and lightly oiled. Make sure the inside of the
housing that accommodates the cleaner element is free of dirt and dust.
The vented area of the crankcase, visible in the photo between the fuel
tank and the air cleaner body (B), allows air from the flywheel fins (C) to
be circulated to the exterior of the engine and is critical to proper
cooling. Ensure that there is no debris within the vent fins that would
impede the circulation of air.
