Engine power loss

[Rpm76 0]

I have a C-161 twin auto with a 16hp Briggs. It's losses power when put under a load and sounds like it miss fires and shoots a flame out the  exhaust at high idle. I flashed the gas tank cleaned the fuel filter, cleaned the carb & rebuilt the fuel pump still the same problem. Any suggestions on where to look next ?  Thanks for any help I can get.

I'm betting you have a bad condenser. Try replacing it with a good one before anything else. They are inexpensive.

Its a mag ignition , no condenser.  Look for a bad wire or a new set of spark plugs.     Wayne

Wayne, you're correct.  I was hasty in the diagnosis.  I do agree it's an electrical problem.
