noob
i was riding my ztr with a opposed onan 16hp and was mowing the yard like i normally do, when my engine cuts down to half speed. it was on full throttle. i wobble my way back to the garage and it totally died in the driveway, I tryed restarting it and noticed it sounded and felt different, so i took the plugs out and did a compression test, 105 in one cyl, and 0 in the other. I doubt since i lost compression so suddenly my rings are dead, even if they were id only have low compression. my moms boyfriend says it may be a snapped valve, bad spring, or snapped cam ( it has 2) but his knowledge in lawn mower engines is pretty limited, since you guys are small engine nuts, what do you think? is it worth replacing? or should i yank the 18hp twin off my utility mower. Thanks guys
