Back fire can be caused by improper ignition or the wrong fuel air mixture. With the engine off remove the air cleaner and look below it. If there is fuel in the pipe then the carburetor is not stopping the flow of fuel and it needs a rebuild.
Rev the engine six or seven times before coming to a complete stop. Rev it all the way to the edge every time you stop.
Kohler for sure
More than likely you have a exhaust leak.Check the headpipe seal
If it is backfiring only when you kill the engine, allow the engine to idle a few minutes before you kill it. If it is backfiring while in use, check the intake gasket and bolts for wear or looseness.
NO, but a good tuneup will probably cure your problems. There is no cure in a can for the symptoms you list.
The best answer for this is: Get a tune-up.
Hey John==Without knowing what you have, it is strictly guessing. Check the firing order. Make sure the compression is ok on the engine. GoodluckJoe
Hattiesburg, Miss. is the US factory for Kohler engines.
Backfiring is caused by incorrect timing, or plug wires installed incorrectly which messes up the firing order. Make sure your plug wires are installed correctly. Can also be caused by an overly rich fuel air mixture.
If it is backfiring the timing is set incorrectly or the spark plug wires are not connected in the correct order.
Exhaust leaks close to the engine.

Backfiring is caused by a clogged/dirty air filter or fuel mixture is too rich. If air filter is clean, close needle valve 1/8 turn. Also can be caused by intake manifold vacuum leak. Check manifod for loose bolts or worn gasket.
The float is probably stuck open.
Most common, a rich fuel mixture will cause the backfiring. Check the condition of the air filter or close the needle valve on the carburetor 1/8 turn. Also, a vacuum leak will cause backfiring. Check the intake manifold for loose bolts or worn gasket.
