How to fix your Signature gas snowblower when its engine won't start
- The snowblower engine needs gas, compression and spark to start, so if your snowblower isn't starting, focus on those. First, make sure the gas in the tank is fresh; older gas can form gummy deposits that interfere with starting. Gummy deposits clog the carburetor so clean or replace the carburetor if it's clogged. Check the fuel line and fuel filter and replace those components if clogged.
- Another easy thing to check is the spark plug-if the spark plug is cracked or has a sooty electrode, replace it. Check the stop switch and replace it if it isn't allowing the spark plug to get current. A good engine tune-up that includes an oil change may help the engine start.
- A failed rewind starter or electric starter won't spin the engine so replace those components if broken. For a quick compression test, remove the spark plug, cover the cylinder hole with your thumb and pull the starter rope. If you don't feel air against your thumb, you may need to adjust the valve lash. A damaged piston, piston rings, or cylinder could cause a compression problem—and it might be time for a service technician.

What to do when your Signature gas snowblower won't clear snow well
A snowblower won't clear snow well if the auger isn't spinning fast enough or sections of the auger don't spin. Then the auger housing and chute can clog with snow. If the snowblower isn't picking up snow well, first turn off the snowblower and clear the chute and auger housing of any clogs or snow build-up.
If the chute is clear of snow or when sections of the auger won't spin, the likely cause is broken shear pins. Replace any broken shear pins you find. Replace the auger if it's damaged.
Adjust or replace the skid shoes to keep the housing at the proper height and allow the snowblower to move easily.
You may need to tune up the snowblower engine when it won't spin the auger fast enough. Adjust the belts and auger drive cable if the engine runs well but the auger doesn't spin fast enough to clear snow. Replace the belts or auger drive cable if damaged. Replace the snowblower gear case assembly if it won't spin the auger.
