This mower has been bullet proof until now. The problem started with the PTO disengaging which I eventually determined was a faulty switch. I disconnected the reverse switches and wired them together and installed the new PTO switch. That now works fine, but now when I engage it the motor has a noticeable rpm drop. When I get into heavy grass it bogs down. The govener moves freely but but does not rev up the motor. I did notice that the voltage drops down to around 10.5 when the PTO engages. I've check fuel lines and filter. What do you suggest?

If it is a twin cylinder, try starting it with one plug wire pulled off, then try it again with the other wire off{other one on}

That will help you...

OK, good call! I discovered that the right side coil was not firing. Since the engine ran smoothly but sounded muffled, I did not expect that. THANKS.
