Russ..... ...glad you got your 8N runnin'. Before you go gettin woundup 'bout overhaulin', since you quote fairly even (cyl to cyl) both dry and wet, I want you to think about your tractors recent history. Its been my experience that even and low compression on a runnin' engine, while wear related, it can also be attributed to sticky rings and valves from varnish and sludge from not changing oil frequent enough or having sat un-runned for long time. (long time could be several months to several years, same effect) Heres what I'd do. I'd get some Marvel Mystery Oil and a small scrub brush like old toothbrush. I'd remove the valve covers behind the carb and scrub the intake valve stems as best as I could. Exhausts don't get gummed up but you can scrub 'em if'n ya wants too. Put 'er back together and then pour the rest of MMO innna oil pan to unstick the rings. Run it for 10 hrs and drain oil and refill with new and filter. Then I'd retake the compression on a warm engine and you might just luck out and not have to spend $1500 for an overhaul, just the price of can of MMO. And keep changing yer oil at least yearly innna the fall..... ...Dell
