Why Snowblower Won’t Start After Summer?

On several occasions, snowblowers fail to start due to fuel system contamination. Such contamination may result from simple reasons like lack of fuel, clogged fuel, or a clogged carburetor. Here are some reasons snowblowers won't start after sitting and hacks to fix that.

How to Diagnose a Snowblower's Fuel System?

As indicated earlier, contaminated fuel is the common reason for a snowblower not starting after summer. Fortunately, diagnosing and fixing fuel or ignition system problems is simple. Firstly, you should clear the carburetor and refill it with fresh gas.

Try igniting the engine, and if it starts, your issue is resolved; however, if that doesn't work, it's likely to be one of the problems discussed above. You can as well perform a gas shot test or do the following:

Common Maintenance and Storage Practices to Keep Snowblower Running

Engines require regular maintenance and storage practices to maintain their effectiveness. For a snowblower, the following measures are crucial;

1. Fuel System Cleaning

Draining the gas tank and cleaning the gas bowl can resolve the issue. However, you may be required to extend the cleaning to the carburetor to fix the issue. You should therefore clean or replace the gas filter after draining the gas tank and gas bowl then you clean the carburetor. You need to have a carburetor cleaner and a carb-cleaning kit.

2. Storing snowblowers Properly

You’ll definitely use a snowblower this winter; it is ideal to store it properly at the end of the season for use in the next one. The storage procedure is simple and is never time-consuming. You may be forced to buy snowblower maintenance tools, but it's worth it.

3. Use Gas Stabilizer

Blended gas has a short shelf-life. It may thicken and damage the carburetor if left to sit for long. Besides, ethanol damages the plastic and rubber components of the fuel system. To prevent these, add a gas stabilizer to keep the gas fresh for longer since it purifies any impurities in the oil. Pro Tip!

4. Close Valves

When storing a snowblower over a long period, ensure the valves are closed since they can let in corrosion into the cylinder if left open. Here are step-by-step procedures to close them:

5. Clean Body and Protect

Using water, detergent, brush, and cloth, thoroughly clean the machine, let it dry, and apply a coat to prevent moisture, rust, and damage.

6. Use Breathable Covers

Breathable covers do not trap moisture. They are thus recommended over the common plastic sheet with which most people are used to covering the machine. Unbeknownst to them, plastic sheets trap moisture which may corrode the machine.


How do I tell if a carburetor is blocked?

To tell if your carburetor is clogged, monitor the performance of the snowblower. You may notice slow performance power; it may release black smoke, stall under load, and have difficulty starting.

Should I run my snowblower out of gas?

Yes. Small engine power equipment, snowblowers included, may be damaged if left with gas while sitting for long periods. It's advisable to drain the gas or ensure it completely runs out to avoid that.

Can old gas start a snowblower after sitting?

No, always use fresh fuel to start your snowblower. Old fuel becomes thick and thus may clog the filter or carburetor.

Bottom Line

Snowblowers are only functional during winter; for the rest of the seasons, they are sitting and are likely to fail. Proper maintenance and storage of the snowblowers should be a routine practice in each homestead after every winter season. However, if you find yourself in such a situation, the above guideline on how to fix a snowblower, not starting after summer, will guide you diagnose and bringing your snowblower back to life. If none of the above works, you should consider visiting your mechanic.
