EXHAUST

If the fuel/oil mixture is too rich, the exhaust port and
muffler may accumulate deposits of carbon. These
deposits will hinder high-R.P.M. engine performance
and increase operating temperatures. Eventually, they
may lead to a no-start situation. There is a character-
istic “flat” tone to the exhaust noise that accompanies a
blocked exhaust.

4.1.

The engine cover must be removed to gain
access to the muffler. See Figure 4.1.

4.2.

Disconnect the high tension lead form the spark
plug.

4.3.

Remove the air filter cover using a T-25 driver.
See Figure 4.3.

4.4.

This will allow access to the screw that secures
the carburetor side of the engine cover.
