Snowblower backfiring. I have a 13 HP Ariens snowblower that started backfiring after about an hour of use. Before I bring it to the shop can any of you suggest what would cause it to backfire and allow me to fix it? Thanks Mueller. Remove Advertisements. Apple Guy.

A flooded engine is another symptom of an engine running rich, so if the spark plug is wet as well you can be almost certain this is the issue. Try running your snow blower with the choke slightly open. If it runs fine, again this is a sign there is too much fuel in the mix for it combust properly. Or you can try checking for any clogged jets and cleaning them if necessary. It is also worth taking a look at the throttle cable to see if that needs adjusting.

Snow thrower backfires

Snowblowers can backfire due to carburetor issues, low-quality or stale fuel, incorrect engine timing, a faulty spark plug, a blocked exhaust system, loose or damaged exhaust components, or ignition system problems. A backfiring snowblower can be both startling and concerning. Backfiring occurs when unburned fuel ignites in the exhaust system rather than in the combustion chamber. This can cause a loud noise and, in some cases, damage to your snowblower. Understanding the possible causes and solutions can help you address this issue effectively. Here are some common reasons why your snowblower might be backfiring and how to fix them.
