Compression release??????

[(Joe)35hpseahorse]

I'm curious as to what the rod going from a guide on the flywheel, to a rocker-arm similar assembly on the head is. The things on the head look like some sort of compression release. Is that what they are?

If you're talking about the old 35's, yep, that's what it is - to assist cranking by the recoil starter.

The early 40hp models incorporated that compression release also. Set the clearance between the release bolt and the valve to (I believe) .020 . It may be .010, I don't recall exactly. Anybody still have the manual on that?

Close enough, Joe. Manual says .015-.025 tappet clearance.

If you are physically able to crank it, it actually will start better with the compression relief disconnected.
