causes hard starting and poor engine performance. Set spark plug gap to

recommended clearance. Refer to engine manual.

BELT TENSION

1. If there is excessive belt play, there will be a decrease in the grinding action,

which could cause cage and machine damage. The normal belt play should be

3/8” to 1/2” which is attained by depressing the top section of the belt at the

belt guard mounting bracket location. When adjusting the belt make sure that

the drive pulley is in alignment with cage pulley. Tighten all engine mount bolts,

adjust the two engine-stop bolts, and tighten lock nuts.

ACCESSORIES INSTALLATION/REMOVAL
