I'm glad you dug till you found the problem.
IIRR I spot faced a shallow place for the spring to set in the closure plate,
But it's been a couple of years, I remember having some question as if to use the plate or not. but it did/does work.

Yeah I will have to add a "spot" or surface to oppose the sring.
But here is the rub, after taking the measurments and doing the math, the the sring in the gen set block, (including the ball) had a cavity that measured .898".
The cavity or "space" allowed for the sring and ball in the cub motor was .832".
SOOOOOO seeing as how the gen set block's hole is .444" deep that means the "spot" I need to add on the closure plate needs to be .388" from the gasket sealing surface. Only prolem with that is the area where the spot will go is rough cast at a depth of .408". already .020" too deep, before I do any machining to it.
Now maybe I'm getting way too worked up over .020". But the Kohler manual is pretty specific about measuring the free length of that spring, that makes me believe they are concerned about it.
I may make a short insert for the end of the spring, and machine the "spot" depth accordingly.
The other question I have to ask is why the difference in spring pre load on the (2) motors? The springs are indentical, as are the balls. The only thing I can think is that the genset was set to run at 1800 rpms, and the cub at 3600rpms. Maybe they wanted the relief valve to kick in at a lower pressure on the genset?

I know right? The problem is finding one. I have yet to see a KT17 seriesII for sale, other than a new short block from Kohler.
Whatever, I'm not giving up!!!!!!!!!!!!!!!!!!!!!!!!
The new gasket set came in last night, as did the new govenor gear set. Now if Aldermans will just call and tell me the rods are in, we will make another run at it.
