No scoring or groove wear.

Which gasket?

Now on the crankshaft there is a groove towards flywheel is there supposed to be a o ring There?
No.
Carb o rings look bad as well

So I think I had some major air leaks and running pig rich was the only way to get it running

I might be wrong but it's worth a try to reseal it and try again


Also the bottom screw under Hsn how do I reset it?
From what I have found, that midrange screw is set so the head of the screw is flush with the outside of the carb body. Roughly 3-3 1/4 turns from seated.
And could this carb be suspect as well
