Thanks for the help Ron, I may need that info later. This Merc is a fresh rebuild. My main objective is to get my 40 Mobile again. Initially, with the complete set-up provided to me from builder/seller. The swithch back to Merc manifold, rochester, and Bubby diz will be on the to-do agenda. I hope I never have to take the head off!
