I have a mvvs 26 redhead that was involved in a earth digging adventure-the crank is not bent and engine still runs-but I noticed when I removed the carb from the case there was a small crack in the throat in the case where the carb was pushed against the case, I used a little rtv and reassembled and engine runs great but I think I probaly should repair properly for service life of the engine-please advise-thanks
