When I'm running the tractor, quite often, it looses 75% power, and the exhaust sounds weird. Sort of muffled.
When I back off on the throtle, it clears up and runs fine for a while.
I was thinking it might be a sticking exh valve, but I noticed, when the motor is off, and I bang my hand on the muffler, a baffle rattles round inside the muffler. It sounds like it is near the outlet end. I believe it's an orig. WH muffler.
I'm wondering if the loose baffle, could move, and cut off the exh. flow?
I'm very close to cutting the end off the muffler and taking a look, but thought I would ask if anyone has had a problem like this.
The next time it happens, I think I will try to stop and put in neutral, and feel the exhaust pressure, with my hand.
