Thank you, Gravel Road and Linctex. This jewel is a re-power on a '77 IH Cadet 80. I got the mower about 2002. It is a very battered example. It mows and uses SAE hardware. Engine has been looked after somewhat. I have been mostly trying to bodge the worn out bushings and elongated holes on the chassis. 2 of the 4 engine mounts were sheared. Partstree wanted like $70 apiece for them. I bought 4 vibration isolators from Grainger that will work. Less than $15. I used Valvoline dino 10w30 from AutoZone and will use the leftover pint in my Toro. The engine was a minor pain to remove because it has 20 yrs of oily grass clippings and belt dust surrounding the mounts. The engine is presently on a couple 2x8s laid across some saw hosses in the yurt. Im gonna push the Inty onto some cardboard and scrape, then wash off the muck with some de-greaser. I have a new air cleaner coming too.
