If your carburetor is corroded or gummed up, go ahead and treat your blower to a new one. Unfortunately, you generally can’t tell a faulty carb from a good one by simply looking at it. However, I replace a ton of faulty carburetors every season. Removing, stripping, and cleaning will fix it. A carburetor that’s not performing correctly is likely, simply dirty. Yep, the carburetor is high on the list of possible suspects. It will protest by stalling, backfiring, running rough, surging and the list goes on Diagnosis The air (oxygen) to gas ratio is everything, even a little off and the engine won’t stand for it.

Dirty air filter – clean or replace filter (if fitted).Bad gas – drain out old gas and replace.There are many other reasons too, but for now, here’s three of the less complex, easy to check and fix causes: Knowing where the noise is coming from does help with diagnosis. The reasons the fuel mixture ignites in these areas of the engine are varied but where they ignite, (intake or exhaust) is often a clue as to what’s going on. It commonly occurs inside the intake system or in the exhaust system. Backfiring happens when a fuel mixture ignites outside the combustion chamber. The pop sound is backfiring and its name gives it away a little. A louder noise sometimes described as a backfire, is generally heard from the muffler.īoth noises are backfires they just sound a little different What Is The Pop Sound? Popping usually occurs through the intake system and can be heard loudest around the air filter. Whatever we call the noise, it’s a cause of concern.

While one person may describe the noise as a pop, another may describe it as a backfire. It is important to use a choke until an engine warms up, if the choke is shut off too soon or the choke is not working correctly, popping from the intake will result. In this post, you’ll learn all the reasons a snow blower makes a popping sound, how to diagnose them and what you’ll need to do to fix them. But hey you know your machine, and if the popping is out of the ordinary, or more pronounced then yes we’ll need to check it out.Ĭommon causes of a popping sound from a snowblower engine, include: In fact, popping noise on cold starts is normal, until it warms up.
