Carbon deposits can form in the muffler
(d)
and in the cylinder exhaust
port. If allowed to accumulate, they will gradually restrict the exhaust
passages, resulting in poor engine performance and hard starting.
Factors contributing to this problem include:
•
Too much oil in the fuel mixture
•
Dirty air filter causing the engine to run rich
•
Excessive engine idling
•
Dirty carburetor
