Some famous guy (who was it?) said you have nothing to fear but fear itself. Once you get the powerhead off, the problem will be obvious. The only possibility that would warrant replacing the whole thing would be if the shifter shaft is worn sloppy loose in the exhaust housing. Anything else is easy.
Actually not funny, but I can’t see why I would be that hard. If it is what is the best way to deal with this. Take the head off and then what?
Sorry man, I read my post just now and it is a bit mean. I’m not going to delete it though so people may get to know my sometimes not so funny sense of humor and maybe not bop me in the nose unexpectedly at some meeting.
