DECARBONING THE EXHAUST PORT
AND THE MUFFLER
In order to decarbon the exhaust port and muffler, the
engine must be removed from the snowthrower frame.
Remove the muffler and scrape any excess carbon
build up away from the muffler and the exhaust port
opening (Figure 231). NOTE: Rotate the crankshaft
so the piston covers the exhaust port. A wooden stick
or dowel should be used so that the metal is not
scratched. Scrape any excess gasket material away
from the exhaust port and the muffler. Install a new
exhaust gasket.
