Rear 10HP Tecumseh engine. I got it used. Always loud so I replaced
the muffler with OEM part number.
I noticed one evening flames coming from the muffler. I took the bowl
off the carburetor and determined that the float had a hole in it.
Replaced the float. Engine still runs LOUD.
Any chance that the hot exhaust and gas combustion ruined the new
muffler? Any chance that long running "ultra" rich engine caused
damage to exhaust valve?
There is no "blow by" engine vibrates a little at idle but runs fine
at mowing speed.
I've got another muffler on order. Any advise on best way to quiet
