Experienced gardeners share their insights in answering this question :
Sounds like Intake valve gap is bad and there is gas in the oil ? Valves cleaned, lapped and head gasket redo . Not too spendy. About 25 dollars total for everything. The lapping tool & Compound, head gasket, OHV rocker cover gasket if equipped. Maybe an ‘inch pound’ torque wrench if you don’t have one, misc socket set, rags, carb cleaner, starting fluid for the tougher build up and some new steel wool pads. Also the valve clearance specs on rocker arms and a few how to vids on youtube about adjusting your valves with feeler gauge and proper torque specs are listed in your engine’s model number Manual online somewhere.

Lawn Mower Engine Operation

The fuel can burn inefficiently for a number of reasons, allowing flammable gases to exit the engine, and if the temperature in the muffler gets high enough, the gases can ignite there and cause backfiring or after-firing, which occurs after you stop the engine.

All you have to do is tell the car not to cut fuel at high revs with a closed throttle – fuel will continue to be pumped into the engine, but when it isn`t ignited it`ll make a break for the exhaust. And we all know what happens then. Yep, flames.
The reason the muffler is glowing red is because the exhaust temperature is off the chart. This (highly likely) means that the ignition timing is out, or the fuel mixture is too lean.
Bad Spark Plug

One very likely reason why a snow blower might backfire when you are trying to start it is a bad spark plug. The spark plug is a very essential part of the snow blower, and when it starts to malfunction, there is a high chance of flames coming out of the exhaust.

Blue or white smoke coming from your engine usually indicates burning oil, which can be caused by: Overfilling the crankcase with oil. Incorrect oil grades. Operating engine at greater than a 15 degree angle.
The demand for additional power will instead flood the combustion chambers with more fuel to compensate for the poor burning. This fuel wastage increases the fuel consumption as the un-burnt fuel air mixture is evacuated as exhaust to cause the smell from your exhaust pipe and sometimes sparks.
Pushed forward by engine backpressure, the broken innards of a catalytic converter will create a blockage. From here, the pressure goes to work on the muffler seam. In short, it explodes.
A: Yes. The exhaust pipe itself. A backfire could shoot a hot blast out the pipe that could spark a fire.
Overheating mufflers can be due to an engine problem as manifested in ignition timing. When the timing is horrible, some of the combustions occur in the exhaust system, making the muffler overheat. By all means, the muffler should demonstrate optimum performance, or else it can become defective.
If your engine is getting more fuel than it needs, a rich fuel to air ratio is the result. When your car has leftover fuel in the exhaust and the cylinders, that fuel explosively burns and creates a loud popping sound. Specifically, here we mean delayed timing, which causes the backfire.
Possible reasons for a backfire include stale fuel in the tank (particularly ethanol fuel), a dirty carburetor, an air to fuel mixture that is too lean, a bad spark plug, and a poorly designed exhaust muffler.
Thick white exhaust smoke usually indicates a coolant leak, which could cause overheating and put your engine at a serious risk of damage. If this is the case, call our auto repair shop for an inspection immediately.
Thick white smoke coming out of the exhaust typically indicates a blown head gasket, a crack in the head, or a crack in the engine block. Cracks and bad gaskets allow the fluid to travel to places it shouldn`t be. If it travels, then the problems begin.
Black exhaust smoke

When your exhaust pipe gives off black smoke, one of the things to get worried about are bad or worn out spark plugs. It means fuel burning in the combustion chamber is not being done 100 percent or burnt fully. It also means that air is not being well mixed with fuel to burn effectively.

Your spark plugs are what supply the spark that ignites the air/fuel mixture, creating the explosion which makes your engine produce power. These small but simple plugs create an arc of electricity across two leads which are not touching, but close enough together that electricity can jump the gap between them.
What are backfire and afterfire? Backfire is a condition described as a loud bang, poof, explosion, etc., while the engine is running or while shutting down. Afterfire occurs after the engine has been shut off. Note: Backfire and afterfire through the carburetor will not harm the engine at all!
Backfires and afterfires are worth paying attention to since they can cause engine damage, power loss, and decreased fuel efficiency.
Damage to Your Engine

Depending on where the exhaust leak is, it could also result in some major engine damage. Another job of your car`s exhaust system is to carry away heat from your engine.

Mufflers` Effect on Performance

An engine is able to generate more power, faster if it is able to get rid of all of the exhaust gases it produces quickly. By their nature, mufflers restrict exhaust flow or create back pressure, which slightly slows down your engine.

If your engine is getting more fuel than it needs, a rich fuel to air ratio is the result. When your car has leftover fuel in the exhaust and the cylinders, that fuel explosively burns and creates a loud popping sound. Specifically, here we mean delayed timing, which causes the backfire.
One potential fire ignition source in a motor vehicle is the hot surfaces on the engine exhaust system. These hot surfaces can come into contact with combustible and flammable liquids (such as engine oil, transmission fluid, brake fluid, gasoline, or Diesel fuel) due to a fluid leak, or during a vehicle collision.
If your engine is getting more fuel than it needs, a rich fuel to air ratio is the result. When your car has leftover fuel in the exhaust and the cylinders, that fuel explosively burns and creates a loud popping sound. Specifically, here we mean delayed timing, which causes the backfire.
This means that the fuel injectors are either adding too much fuel or that the intake valves aren`t letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter. If your engine is running this rich, it can cause serious problems.

I have a cub cadet 2165 I just put in a new battery and it is slow turning over any ideas?
ANSWER : If battery is good and everything is hooked up right. Most likely could be the pto clutch bearing. Not the bearing on the pulley but on the clutch inside. Had the same problem, took the spark plugs out got it free. Turned over easy with plugs out, Started right up after and then burned up my bearing. Don’t burn up bearing. If do field assy. For that is 200$ if you can get away with just that. Otherwise 350-400$ for full assy.
