Installing the Muffler
The muffler mounting accessory package 
includes mounting screws (2), lock washers 
(2), muffler gaskets (2) and L- wrenches (2).
1.  Put a lock washer on each of the muffler 
screws. Push the muffler screws through 
the cylinder head.
2. Place the muffler gasket over the engine 
mounting screws.
3. Align the mufer gasket with the exhaust 
opening and the muffler mounting screws.
4. Tighten the muffler screws. 
IMPORTANT: Tighten the muffler screws after  
 five tanks of fuel. The muffler screws may 
loosen from heat and vibration.
 It is important that you tighten the muffler 
through bolt after each of the first three,  
full tank engine runs. The heat will cause 
expansion of the through bolt and muffler 
body parts. After the third tightening, no 
further muffler loosening should occur.
To tighten the muffler through bolt:
1.  Loosen the muffler lock nut. 
2. Tighten the muffler through bolt screw.
3. Tighten the mufer lock nut.
