Has anyone ever seen an engine that was worn out enough that the compression was low but there were no other signs of wear? No burning oil, leaking oil, hard starting, overheating, nothing?
Here's the back story. A neighbor bought another piece of property. She told me she wanted to get her "old mower" running again to just leave over there and save wear on her good mower. The old one is a JD 188 with a 17 horse liquid cooled Kawasaki two cylinder on it. She said she quit using it because the compression got so low it wouldn't mow much.
I brought it home and went through the carb. It had been sitting about 10 years. It was only used about five years but the yard is four acres or so. The thing runs like brand new. No misses, no burning oil, nothing. I mowed with it a bit and it certainly is not putting out 17 horses. I checked the deck and hydrostat - it's power related for sure. I figure the valves must need adjusting, so I came in for lunch and to cruise the Internet and see if I can find info on adjusting them. It just got me to wondering about compression. Every tractor or vehicle I've had was either leaking, knocking, smoking, or impossible to start long before the compression got low enough that it couldn't do any job.
