Still thinking about why it was running hot and the exhaust stack was burning up.
One of the members posted this service bulletin that he used on his 58 35HP Johnson on the AOMCI Facebook site.
The head in the bulletin looks very similar to my 1967 33HP (picture below).
What does everyone think about giving this a try to eliminate my burning exhaust stack? I imagine I could reverse it if anything goes wrong?
Thanks,
Bob D
