How to Troubleshoot Gas Snowblowers

Engine Won't Start or Runs Erratically

• 1

  Turn the choke control to "on." Try to start the engine again.

• 2

  Connect the spark plug wire to the spark plugs. Examine the spark plug for signs of dirtiness or damage. Clean the spark plug or replace it if it is cracked or burned. Use a feeler gauge to check the electrode gap. Reset it to .030 if necessary.

• 3

  Check the fuel level. Fill the tank with fresh gas if fuel is low. Drain the fuel tank and refill with fresh gas if the gas has not been replaced in a long time. It may be stale.

• 4

  Prime the engine. Make sure oil reaches the "full" mark. Attach the spark plug wire to the spark plug and securely fasten the loop at the end of the wire over the spark plug's metal tip. Put the auger and drive controls in disengaged or released position. Move the throttle control to fast and insert the ignition key until it snaps into place.

• 5

  Push the safety key completely into the switch. Start the engine again.

• 6

  Contact the manufacturer for service if none of these help. You have a more complex engine problem that needs professional diagnosis.

Power Problems

• 7

  Reconnect the spark plug wire if the gas snowblower loses power frequently during use. Tighten the spark plug wire with a pair of pliers if it seems loose and try using the snowblower again. If this does not solve the problem, move on to the next step.

• 8

  Remove ice and snow near the gas cap. Brush any ice and snow from the vent hole so that it is completely clear. Call the manufacturer or repair person for service if the snowblower continues to lose power.

• 9

  Adjust the auger control cable. Thread the lock nut downward to extend the length of the cable and stop the auger from turning.

• 10

  Adjust the drive control cable if the unit will not move forward. Thread the lock nut outward to extend the length of the control drive cable and help the unit move freely.

• 11

  Check the drive belt for looseness or damage. Replace the drive belt if necessary.

Snow Removal Problems

• 12

  Stop the engine and disconnect the spark plug wire if the unit does not discharge snow. Clean any debris from the chute assembly and auger housing with a long stick or other tool.

• 13

  Check the auger for obstructions. Remove the obstruction if necessary.

• 14

  Adjust the auger control cable. Thread the lock nut downward to extend the length of the cable and stop the auger from turning.

• 15

  Check the auger belt for looseness or damage. Replace the belt if it is torn, loose or appears damaged.

• 16

  Check the shear pins for signs of damage. Turn off the engine, remove the key and replace the shear pins if necessary.
