2.Push up on the shift arm assembly as far as it will go. Thread the ferrule up or down the shift rod and align with the lower hole on the wider side of the shift lever assembly behind the handle panel. Secure the ferrule to the shift arm assembly again with the hardware earlier removed.

Models 614, 644, 664, and 6A4:

3.Push down on the shift arm assembly as far as it will go. Thread the ferrule up or down the shift rod and align it with the hole closest to the shift knob on the narrow side of the shift lever assembly behind the handle panel.

NOTE: Make certain to check for correct adjustment of the shift rod as instructed in the Final Adjustments section before operating the snow thrower.

CARBURETOR ADJUSTMENT

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.

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

Refer to the separate engine manual packed with your unit for carburetor adjustment information.

DRIVE WHEELS

The wheels may be adjusted for two different methods of operation. The adjustment is made by placing the klick pins in one of two different holes on the right side of the unit. See Figure 27.

1.One Wheel Driving—Place klick pin in the outside axle hole on the right side. This position gives power drive to the left wheel only, making the unit easier to maneuver.

2.Both Wheels Driving—Place klick pin in the hole in the hub next to the rim on the right side. This position is good for heavy snow as there is power drive in both wheels.
