Power Pro Snowblower won't start: Common Causes & How to Fix
1 Power Pro Snowblower Spark Plug
Most Common Solution
Repair Instructions:
Take a close look at the spark plug to see if it is worn down or damaged. Check if the porcelain insulator part has any cracks, the electrode metal tip is burned away or harmed, or there is a lot of carbon buildup at the electrode. If you notice any of that, you'll want to replace the spark plug with a new one. You can also use a spark plug tester tool to check if the plug is bad. When you're cranking the engine over, there should be a strong spark jumping between the tester terminals. No spark means the spark plug is defective and needs replacement. A good spark shows the plug is still working properly.
How to Replace Power Pro Snowblower Spark Plug
- Make sure the engine is completely cooled off before starting. This ensures you don't burn yourself on hot engine components.
- Locate the spark plug. It is usually easily accessible once you lift the cover or remove panels on the engine housing. Refer to your owner's manual if needed.
- Disconnect the spark plug wire by grasping and pulling on the rubber boot, not the wire itself. This will allow you to remove the plug.
- Use a spark plug wrench to loosen the plug by turning it counterclockwise. If you don't have a wrench, a socket of the proper size will also work.
- Remove the old spark plug once loosened and inspect it. Look for damage like cracks or excessive wear. This can indicate issues with the engine.
- Check the spark plug gap of the new plug using a gapper tool. Adjust it to the proper measurement if needed. Refer to your manual for the right gap size.
- Carefully insert the new plug, being sure not to cross-thread it. Tighten with the wrench to the torque spec in your manual.
- Reattach the wire to the spark plug. Make sure the connection is snug.
- Start the Power Pro snowblower and allow the engine to warm up. Make sure it is running properly before using the machine.
2 Power Pro Snowblower Carburetor Repair Kit
Most Common Solution
Repair Instructions:
The issue could be that the carburetor has gotten clogged up. This usually happens when you leave fuel in the Power Pro snowblower for a long time. Over time, some of the ingredients in the fuel can evaporate, leaving a thicker, stickier substance behind. This sticky fuel can plug up the carburetor and make the engine run rough. To fix it, try using carburetor cleaner to unclog the carburetor. Spray it in there and let it sit to break down the gunk. If cleaning it out doesn't work, you'll probably need to rebuild the carburetor entirely or just replace it with a new one. Leaving old gas in is a common cause of carburetor clogs, so if your Power Pro snowblower engine is running poorly, inspecting and cleaning the carburetor is a good place to start. A rebuild or replacement may be needed if it’s too gummed up.

3 Power Pro Snowblower Flywheel Key
Most Common Solution
Repair Instructions:
The problem could be that the small flywheel key has snapped in half. The flywheel key is a little metal part that fits into the crankshaft and connects with the flywheel. If the Power Pro snowblower engine suddenly stops because you hit something hard, the flywheel key is designed to break in half. This prevents damage to the rest of the engine. To check if the flywheel key is broken, take the flywheel off the engine and look at the flywheel key. If you see a clean break on it, that's the issue. The flywheel key acted like a safety fuse - it broke so other engine parts wouldn't. To fix it, just replace the flywheel key with a new one. That will get the flywheel spinning properly again.
How to Replace Power Pro Snowblower Flywheel Key
- Disconnect the spark plug wire to prevent accidental starting while working.
- Remove any covers or panels necessary to access the flywheel on the engine.
- Clean the flywheel of any debris or oil buildup. Locate the keyway where the key fits.
- Use a flywheel puller to carefully remove the flywheel from the crankshaft if it does not come off by hand.
- Inspect the flywheel key in the keyway and remove it if damaged or sheared off.
- Lightly file or sand any burrs or roughness in the keyway so the new key fits flush.
- Insert the new flywheel key, making sure it is seated fully into the keyway.
- Align the flywheel so the keyway slots into the key on reinstallation.
- Tighten the flywheel nut or bolt to the specified torque in your owner's manual.
- Test run the engine and make sure the flywheel runs true without wobble.
- Reinstall any covers or guards removed earlier.
- Allow the engine to warm up before subjecting the Power Pro snowblower to heavy use after flywheel replacement.

- Check engine performance regularly to identify any potential issues with the new coil.
6 Power Pro Snowblower Recoil Starter
Common Solution
Repair Instructions:
The ignition coil provides electricity to the spark plug when the engine is on. If the ignition coil is busted, the engine might not start up. Before swapping out the coil, check to make sure the spark plug itself is good. Confirm the plug is sparking right. If the spark plug checks out okay, then use a coil tester tool to test the ignition coil. This can tell you if the coil is no good. If testing shows the ignition coil is defective, then put in a new one. The ignition coil is what gives the spark plug its spark. So if the engine won't start, testing the coil can show if it needs replacement or if the problem is something else. Check it after making sure the spark plug is fine.
