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.
Adjust or replace the snowblower skid shoes
The skid shoes control the height of the auger housing. They wear down over time. Adjust the skid shoes as needed to maintain the proper height of the auger housing. Skid shoes are reversible; turn them over if one side is worn out. Replace them when both sides are worn out.
Adjust or replace the snowblower belts
A worn or loose belt can slip or squeal when the snowblower is in use. Physically examine the belt and pulleys. If the belt is worn, replace it. If the belt is sound, adjust the pulleys to tighten the belt.
Replace the snowblower friction disc
The friction disc is attached to the axle that drives the tires to move the snowblower. Examine the friction wheel to see if it's preventing the snowblower from moving. If the friction disc is worn or damaged, replace it.
Do a snowblower tune-up
A tune-up restores the snowblower to its peak operating condition. A tune-up includes changing the oil, cleaning the engine, replacing the air filter, checking the ignition system, inspecting the carburetor, testing the battery, adjusting the throttle and choke controls, and adjusting and lubricating all moving parts.
Repair or replace the snowblower tire or wheel rim
Inspect the tires should be inspected before each use. If a tire is flat, repair or replace it. If the wheel rim is damaged, replace it.
Adjust the snowblower drive clutch cable
The drive clutch cable moves the drive wheel into contact with the friction disc, which rotates the axle so the snowblower moves. If the cable isn't moving the drive wheel into contacts the friction wheel, adjust the cable.
You need a spark to fire up the engine of your snowblower, and that spark comes from a spark plug. You can replace one in minutes.
Replace the fuel line on your snowblower if it's cracked or damaged.
The shear pin breaks if you hit hard-packed snow, to protect the engine from damage. Your snowblower auger won't rotate until you fix it. You can replace it in about 10 minutes.
This video shows how to adjust a snowblower's auger control.
Learn how to tighten a snowblower drive control if the drive slips or doesn't engage, and how to loosen it if the snowblower creeps when you disengage the drive.
