eXmark Lazier Z loss of power

[Phil P]

Hello all

I have a eXmark Lazier Z 60 inch mower that we have been running for about 12 years.

We ha developed a back fire that results in reduce power to the point we have to disengage the blades to keep it from stalling.

After recovery it will operate again until the next back fire.

I have run out of options except the muffler. The inside of the muffler can brake off in sever pieces and vibrate around in there until they cover the exhaust outlet and cause this type of failure.

So now my question how do I get the muffler off?

You not going want to hear this from the image post it looks like the engine has to comes off as you can't access the nuts holding the muffler on the cylinder heads.
