If the engine responds sluggishly or quits after running for a while, a clogged converter could be to blame. Catalytic converters can overheat because of excessive amounts of unburned gas caused by a misfiring spark plug or a leaky exhaust valve. In addition, a failed oxygen sensor can cause overheating.

What causes sparks out of exhaust?

A backfire is caused by a combustion or explosion that occurs when unburnt fuel in the exhaust system is ignited, even if there is no flame in the exhaust pipe itself. That unburnt fuel can be caused by a variety of mechanical problems, and here are some of the most common reasons for a backfire: Running too rich.

Why is my lawnmower sparking?

Is it normal for an ATV exhaust to be red?

You naturally start worrying whether this is normal or not. A glowing red color is usually an indicator of fire-bursting temperatures, which is rarely a good sign, especially when it involves our expensive toys! Any ATV will generate a lot of heat when you push it to its limit.
