There were no scratches or gouges in the cylinder walls. I noticed the head bolts didn't seem too tight & that there was quite a bit of carbon & oil around one of the head bolts so for good measure I went ahead & replaced the gasket to eliminate that as an issue. The cylinder walls actually looked in good shape for a 15 year old lawn mower engine. What should the compression be and what would be the best way to check compression?

The only way to accurately check compression is with a compression gauge. Compression should be 90 or above.
OK Thanks. I have that at home so I'll check it & post the results.
I'm watching this one as I have the same exact motor and problem. Was mowing one day and it just died. Pull cord and nothing. Hit primer bulb a couple times and fired up and just died. Mower is old and needs replacing anyways but am curious as to what causes this.
Gave up on this engine. Found a non-vector 6.75 HP mower & decided to fix it instead of fighting with the vector. That mower is not a self propelled so I'm gonna take that engine & put it on this mower.
