ok…I will try running it outside the tank.
Will let you know.
Will let you know.
I’m not sure just what you mean by "running it outside the tank"…..
Please don’t run the water pump impeller dry…
And again, I don’t think you will be able to judge much by running it with the gearcase removed for the reasons I mentioned previously…
I am confused because the sooty drain relief reed is on the bottom cylinder, the one that seemed to be firing OK…
So, would probably just put the engine on a boat and try to go for a ride to get the needles dialed in better and see how it runs….
