Advice please: Unusual Kohler engine problem
My friend said he could hardly mow his grass because the engine had no power.
I checked the usual stuff. The plug looked good; good color. The fuel bowl was clean and no contamination; fuel flow good.
Starts up easily but has a very unusual sound in the exhaust; almost like a blown head gasket, but no evidence of that. Compression is 60# cranking, but it has ACR. Within a minute or two, the muffler is cherry red. Runs at high and low speed well, but just has a very unusual sound.
If I remove the muffler to check for blockage, how long can I safely run without it?
