PROBLEM CAUSE SOLUTION
•
Wrong valve clearance. Adjust valve clearance,
•
Low compression because of dirty
valves.
Clean valves. Take off the injection bent and
inspect the outlet port. When little rust in the
port clean the valve by taking off the valve
spring and rotate until clean. When the outlet
port is strongly affected by rust, the exhaust
system is not properly installed (see paragraph
5.4.3). Contact WhisperPower service
department for advice.

•
Faulty fuel lift pump.
Try the pump by manual operation. Repair
when faulty or replace
•

Engine exhaust smokes
•
Faint blue smoke - generally the result
of light load
Increase load.
•
Heavy blue smoke - caused by
lubricating oil: Overfull oil sump or worn
cylinder bore, stuck broken or worn
piston rings.
Check the oil level.
Check the compression.
•
Black smoke –incomplete combustion
caused by: Overload, choked air
cleaner, inlet temperature too high,
unsuitable fuel or water in fuel.
Check air cleaner
Check the fuel .
Check for overload.
