HOW TO FIX A HARD-STARTING SNOW BLOWER WITH SEA FOAM
As with most small engines, the most common no-start cause is old, degraded, or contaminated fuel.
We have all been there. To add insult to injury, working in the cold is not fun. It makes the process more risky for both you and the machine as plastic and rubber becomes much more fragile in the cold.
KEEP YOUR FUEL CLEAN
Preventive cleaning is the most commonly neglected piece. While debris is less apt to get in the tank of a snowblower vs. a lawnmower, it’s still possible. Your snowblower is also more likely to have been used less frequently and in a shorter season than the typical mower. Less use means older fuel, on average. Keeping your fuel system clean is an easy way to prevent rough operation and hard starts.
BREAKING DOWN VARNISH
Old fuel leads to varnish building up in both the fuel tank and lines, as well as clogging small passages and jets inside your carb. If you want your snow blower engine to start reliably, fuel must be able to travel freely as designed. Break down gummy tar-like fuel deposits by adding Sea Foam Motor Treatment to your snowblower’s fuel.
For general maintenance, add an ounce of Sea Foam per gallon of fuel. The Sea Foam allows broken-down old fuel to reliquefy so it can run out of the system. For cleaning, add two ounces of Sea Foam per gallon or more. It is safe for all engines and you can’t add too much. Staying on top of this practice will ensure your blower’s fuel system doesn’t let you down when you need it most.
If the snow blower isn’t starting due to a gummed up carburetor or other gum/varnish issues in the fuel system, Sea Foam will help clean it up and get it running again. Here are step by step instructions for how to use Sea Foam:
- Remove the old fuel from the tank, then drain the fuel from the carburetor (usually a screw)
- Add a cleaning dosage of Sea Foam to an empty tank followed by a small amount of fresh fuel (a 1:2 ratio of Sea Foam to fuel is a good cleaning dose. Add 4 oz of Sea Foam and 8 oz of fuel).
- With Sea Foam mixed in the tank fuel, rope pull/crank or press your primer bulb 3 or 4 times to draw the fresh fuel and Sea Foam into the carburetor
- Then let the engine sit overnight to allow the Sea Foam to dissolve any fuel residues from the carburetor (older or excessive gum/varnish may need to soak two to three days).
- Once the engine starts, the Sea Foam in the fuel will continue to clean and help restore lost engine performance.
