Thread: knock, with backfire thru carb

Thanks Kurt.

I will have it apart this weekend. If I don't have to pull the engine, that would be best for me, but, "what will be, will be"

After looking in the valve galley, I can see number 8 cylinder exhaust valve does not move.
I am most of the way along pulling that head.
Can you just have the one valve fixed, and then put that head back on?

I really think the previous owner over revved and engine with a mild cam, and stock lifters/rockers, and floated the valve.

Hopefully the piston is OK.
