Carburetor

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 mufflers.

Minor carburetor adjustments may be required to compensate for differences in fuel temperature, altitude and load.

Service

Augers

The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. See Figure 27 . If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts will shear. This type of nut is used where vibration occurs.

•If the augers do not turn, check to see if the bolts have sheared. Two replacement shear bolts and hex lock nuts have been provided with the snow thrower. Since lock nuts cannot be threaded onto a bolt by hand, use a wrench. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.

Shear Bolts

•To remove shave plate, remove carriage bolts, belleville washers and hex nuts which attach shave plate to the snow thrower housing. For location of shave plate, see Figure 27 .

•Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Tighten securely.

Replacing Belt

WARNING: Disconnect the spark plug wire from the spark plug and ground.

Auger Belts

•Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. See Figure 28 .

•Reassemble new skid shoes with the four carriage bolts, belleville washers (cupped side goes against skid shoes) and hex nuts. Make certain the skid shoes are adjusted to be level.
