27hp Kohler pro

Just purchased a Scag Tiger Cat with 27hp Kohler command pro with 34 hours, when the engine is at idle it sounds like it rattles almost like a shield is loose when you up rpms to mow it goes away. I have had all Kawasakis before is this the nature of these, don't know what this means if you just block off any of the exhaust it goes away. Does this sound like an issue.

Check to see if there are bolts loose or missing on the exhaust mount.

Broke loose baffle inside the muffler is my guess, With the muffler cold of course bump on it with the palm of your hand and see if it rattles....

The baffles in muffler are broken & moving around. Just cut the end open & remove broken baffles and then re weld exhaust back together. This is what I did with my 27 Kohler.

Does the engine require a certain amount of backpressure, so it shouldn't harm the engine if baffles are removed
