Snow engines
Unlike the summer engines, the snow engines are not
equipped with spark arrestors.
To remove/replace the muffler:
1. Remove the muffler shroud by taking off the six
screws that hold the muffler cover in place using a 10
mm wrench. See Figure 3.6.
2. Remove the four screws securing the muffler shield
using a 10 mm wrench and lift it off of the engine. See
Figure 8.7.
3. Remove the two muffler nuts using a 13mm wrench
and lift the muffler off of the engine. See Figure 8.8.
4. Clean all of the gasket material off of the cylinder
head and the muffler (if reusing the muffler)
NOTE: The MTD engine uses a graphite exhaust gasket.
It is not reusable and must be replaced every time
the muffler nuts are loosened.
5. Install a new gasket.
6. Install the muffler and tighten the muffler nuts. Refer
to the table at the end of Chapter 10 for the proper
torque.
7. Test run the engine before returning to service.
