• Remove the left crankcase cover.

• Inspect if the transmission belt is worn.

• Measure the width of the belt.

• Replace the belt if its width is less than the service limit below:

Service limit 19.0 mm

0.748 in.

• Refer to the drive pulley removal and installation procedure for replacement. Only use a brand identical belt
when replacing.

DENI CARBURETOR – PD24JH

CARBURETOR REMOVAL

• Turn fuel to OFF position

• Remove throttle cable, choke wire, fuel line, and vacuum line.

• Loosen clamps on intake manifold and air fi lter.

• Remove carburetor.

CARBURETOR DISASSEMBLY AND INSPECTION
• Remove the four screws on fl oat bowl and remove fl oat bowl.

• Check fl oat bowl for dirt and fuel residue.

• Remove fl oat, fl oat needle valve, main jet, needle jet holder, needle jet, and pilot jet.
