Sorry, I forgot to mention that I rebuilt the carburetor, the float looked fine, and I adjusted the mixture while it was running on the boat more than once to get everything I could out of it.
I will have to run it in a barrel and kill one cylinder at a time and see what happens, that seems to be the logical next step. I figured that if one cylinder was not pulling it’s weight then it would show up in the plugs. But it is quite possible that I haven’t run it enough to show a difference.
I’ll let you guys know what I find out.
You know, I meant to change that lower seal a long time ago when I first went through this motor, but I cheaped out and elected not to. It sounds like I should have done this in the first place.
