I would have to agree with you. I have never seen an engine that had a dead cylinder that did not have a miss. This engine runs relatively smoothly through all RPMs. I ran the compression test three times on that cylinder and got zero pressure each time. It seems odd that the compression tester would give solid readings on the other cylinders but zero on this one. Maybe more testing is needed. Thank you for the advice!
