 Style 2 Controls:

To adjust the tension on the belt, first adjust the cable at the cable bracket on the handle. Proceed as follows:

• Engage the drive clutch control handle (squeeze handle against the upper handle). Measure the spring on the

drive clutch cable. It should measure approximately 2-1/4 inches long as shown in Figure 11B, inset.

• If adjustment is necessary, loosen the screw which secures the cable bracket to the upper handle. The cable

bracket is slotted, slide it up or down the handle as necessary to achieve the 2-1/4 inch measurement. 

• If the measurement can not be achieved in the previous step, unhook the Z end of the spring from lower hole

and insert into the higher adjustment hole.  

• Check the spring length as instructed in step one.

CARBURETOR ADJUSTMENTS

WARNING: 

 If any adjustments are made to the engine while the engine is running (e.g. carburetor),

keep clear of all moving parts. Be careful of heated surfaces and muffler.

 To adjust carburetor, refer to the separate engine manual packed with your mower.

NOTE: 

A dirty air cleaner will cause an engine to run rough. Be certain air cleaner is clean and attached to the

carburetor before adjusting carburetor.
