See if there is an oil pressure guage on the dash. When you start the machine it probably has a low oil pressure shutdown which shuts the engine off when you release the start button. This is an interlock. Watch the oil guage and keep the start button engaged until you see oil pressure, release the button and it will continue to run at that point. Your second issue may be a function of the choke. If you are having to choke the engine to start, you may have to play with the choke position to keep from overfueling the unit which may cause it to stall and possibly backfire as it has to much fuel to be burned on the compression stroke, and is igniting occasionally on the intake stroke. Hope this helps. Marvin

It is possible that your voltage regulator is shot but before purchasing the volt regulator try flashing the fields first and make sure the brushes and rings are clean.

fuel problem, the float in the carborator is stuck, if you tap on the carborator bowl it will probably get freed up.if not take the bowl off and spray the insides with carb. cleaner.

go to any auto parts store and get one of the products they have to remove the gum in the carburator and line. Some of the products are simply poured into the gas tank along with some fresh gas. good luck.
