The   fuel   filter  is located  in the  fuel  line  on the left side 
of the engine by the starter motor. Replace the filter yearly. 
Prior to the removal of  the  old  filter, note the direction of 
fuel flow as indicated on the filter. Have towels readily 
available in order to quickly remove any fuel leakage. 
Always  use  new  hose clamps and ensure the security of 
the new filter by lightly pulling on each hose. Always 
perform maintenance outdoors or in a well ventilated area. 
Do not smoke or allow any open flames in the vicinity of any 
maintenance activities. 

3.2 Changing your fuel filter: 

1) Locate your fuel filter and mark the direction it is facing.

2) Clamp each side of the fuel filter to minimize gas spills.

3) Remove the clips from each side of the fuel filter and
remove the fuel filter.

4) Place the new fuel filter in the same direction as the old

and place clips back into place and remove clamps.

The air cleaner is the engine’s only defense 
against damaging foreign particles. It is very 
important that the air cleaner element is inspected 
prior to each use. Remove the element and tap its 
sides in order to remove debris. Do not blow the 
filter out using compressed air. Doing so will 
greatly reduce the air cleaners effectiveness. 
Replace yearly; more often in dusty environments. 
Adhering to these practices will help prevent loss 
of power and premature engine failure.

 

3.3 Changing the air cleaner 

1) Locate the air filter and lift up the cover.
2) Loosen the tensioner on the right side of the

air filter.

3) Clean or replace paper element.
4) Place the paper element back into place and

tighten the tensioner.

0.03 in using a feeler gauge.

3) If the spark plug is worn, overheated, wet or carbon

fouled replace the spark plug.

4) Install the plug into cylinder head and torque to 16

ft.-lbs. Be careful not to overtighten the spark plug.
