Check the gas cap! If it's vented it might be clogged.

Tried that, this thing goes along and then has a power loss, motor starts knocking and plinking. I then turn of the PTO and it continues till I throttle down and then she will pur like a kitten. Oh yea by the way I said it was a 114 and its a 140.
Could or is this a carb problem.(never been rebuilt) The motor was overhauled 2 years ago. Could this be Ignition.
Thanks in advance

Sounds like a lack of fuel. I would remove the fuel tank and flush it out. You probably had debris floating around in the tank that plug the fuel line port. Units will run fine at idle, under full power for awhile and then lose power, cough and sputter until the engine dies or is returned to idle.

Another possibility is the condensor is breaking down under heat and use. Change the points and condensor and see if that helps.

What about a sticky valve or maybe burnt. Would this be possible

i have a 10 horse kohler in a cub cadet.i had the same problem.it turned out to be a leaking exaust valve.the way i found out was to put air preasure into the sparkplug hole and checked for air leaking out of the muffler,carb.i replaced the valve and ground the seat.it's perfect now.

Post your engine's model numbers so I know what you have.
But a simple valve clearance adjustment could have you mowing
again, but without knowing what you have, I can't add much

put a new fuel filter on!
