A couple of weeks back my Bolens 1220 with a Tecumseh 12 horse started running roughly. I found the carb plate loose and both brass screws missing. I replaced the screws (added loctite) and went back to tilling. Then I got to wondering where did those screws go? Could they possibly have worked their way into the cylinder head? Looks like the answer is yes.
I was thinking of flattening the head, replacing the gasket, and hoping for the best.
Any other ideas as to what I should/should not do at this point?
