Gas Snowblower: Won't self propel

Inspect the drive clutch cable and adjust if it's loose. Check the drive belt for excessive wear and replace it if necessary. Reinstall the drive belt if it slipped off a pulley. A worn friction disc won't propel the snowblower so check the friction disc and replace it if it's worn.

The snowblower also won't move with the auger housing or scraper blade scraping the ground. Tighten the scraper blade if it's loose and replace it if damaged. Adjust or replace the skid shoes to lift the auger housing to the proper height. Check the tires and rims and replace a rim if it doesn't spin smoothly on the axle. Tune up the engine if it runs rough and doesn't have enough power to propel the snowblower.
