Kaw FH641v-DS19 compression

Hey guys I'm having a issue on this engine... it came off a Toro z 48"
last July my Employees came in saying the engine started smoking a bunch so i checked the Oil and there was little to no oil so i parked it and it has sat for the last 6 months and seeing as how it's FREAKING cold out i started tearing into my broken equipment...

First I did a compression check and one side was at 165 the other was at 135 and both plugs were burnt out.

the engine has 1040 hours

does anyone know what the compression should be on this engine?

what should i do next?

I don't consider myself a mechanic but i do have enough skill to fix a lot of engine issues.

Actually, the comp reading is a bit high, usually runs around 95-100. Prolly way carboned up. You should do a cyl. leakdown test. That will tell ya what's going on, before ya tear into it.

What's not good it's the difference between the two.
That will not be a gasket problem
Your rings are bad if the cylinder didn't get damaged the cost to repair will be less.

Holy mother of carbon it is thick!!! it fell out in chunks... I'm ordering new valve's and the gaskets should be here any day, unfortunately it's to late to do a leak down (the things i wish i had known) i can either wait for the gaskets and then do the leak down or just go ahead and tear it down and replace rings??? what would you do?

cylinder is still good so I'm thinking do the rings just to be safe...
