Nice! I had the same issue with a 235 years and years ago. It got me home but I thought I had busted something for sure. It would almost stall the engine every other revolution. The intake on #6 was still working sort of, but the exhaust valve was not getting open. So every other time it came around it would stumble hard. Then the intake would open and it would backfire and on it went. Tightened the bolt and ran it for years afterwards. Very forgiving engines these are.
