Calling my fellow shade tree mechanics!
I have a photo and an enlargement of part of it.
(I think the mechanic got me good...)
These are the headbolts of the cylinder in question.
Status was: mechanic ran generator for 3 hours until it stumbled.
He took the head off the questionable cylinder.
He diagnosed bad rings based on the top of cylinder being rather clean at two places of the circumference.
He said he discussed it with B&S.
he ordered a new head gasket, cleaned off the piston top and the mating surfaces and re-assembled the genny.
he did not:
run it again for three hours
did not clean the headbolts.
I then decided to change the rings and disassembly began. :sb:
I noticed that two of the headbolts were heat discolored, but put them aside. (Six were not discolored.)
My thinking began after much doing
There HAD to be a reason for the heat discoloration!
So I looked at the headbolts again tonight and present these photos for your comments. (I already have an opinion, but now I need YOURS!
