Model 28N707-1036-E1 Briggs & Stratton Cast Iron Cylinder. Backfire through exhaust, and rough idle. Acts like it wants to stall at low idle.
Rebuilt and painted the engine, cleaned piston, rings, grooves, and head (Gaps Were Good) rebuilt the carb with a kit & cleaned thoroughly. All new gaskets, and seals. New air, fuel filter, and fuel line. Cam, lobes, and crank looked good. Triple checked timing marks. Checked compression release, and that was good. I also took the flywheel off again, to check the key and that checked out just fine. (I’m stumped)!
.30 for spark plug
.003 for intake
.005 for exhaust
Just received the new B&S magneto, and plug, going to install that Monday. 7/8/13. I will post updates.
(Update) The problem was the Magneto. Runs like new now!

Any help, or advice would be appreciated.
