Valve Lash is incorrect, can also be caused by injector fallout ( injector over heated and continues to dump fuel long past its cut off point ).

Exhaust backfire

Check the following: 1. cracks in the distributor cap. 2. Ignition timing and advance 3. plug wires and plugs could be bad. 4. If carbureted- the power valve might be leaking. 4. Valve rocker arms over or under tightened. 5. vacuum leak. - check with a gauge. 6. Cam timing off.

Backfiring is caused by either the firing order being incorrect or the engine timing is incorrect. generally backfiring through the carburetor is caused by incorrect firing order. confirm the distributor is inserted properly and double check firing order beginning with cylinder number 1.

Backfired then quit

sounds like your exhaust valves aren't opening up which means either your cam is out of round, push rods are bent/flatten rocker arms broken, broken valve stem/seat, hopefully just the valve got stuck closed due to carbon build up

Briggs & stratton mod. 406777-0115-E1 engine backfires thru exhaust

This is a true tale sign of a valve being out of adjustment or possible burnt or sticking. Most likely its just out of adjustment. Setting them to Book Specifications of: Valve Clearance (cold) IN and EX .005" (0.13 mm) should take care of the problem. Since you said that it runs fine rules out the possibility of a sheared flywheel key, though I have seen one run with it slightly sheared. Thanks; George

I think you have a valve problem. Need to remove valve covers and look for loose or broken rocker arms. If an exhaust valve does not open because the rocker is broken the trapped combustion gasses will revert through the intake when the intake valve opens. This can interupt the intake flow to other cylinders and prevent starting.

22 hp. Kohler engine has new push rods and rocker arms and 1 new exhaust valve. engine is getting fire through spark plugs but will not start. backfires sometimes when you first hit the key, but will not...

check the valve lash sounds like you have them adjusted wrong, put the piston top dead center, with the rocker arms level with each other before you set them
