Mike K and Pat,

Thanks for your info. I read over your posts and decided to do the easiest thing first.

Recently I read an article in SSOS from 1994 (not sure of date) where Ed Winfield said that with 6.0 head the plugs should be gapped at .025 and for a 7.0 head they should be .022.

I did only one thing and that was to regap the plugs NGK (BP5ES) from .022 to .040. The difference is amazing! Idles and runs much better.

I will check into the other items you mentioned later ... I ran out of time!

In particular the Platinum plugs and distributor checks.

The B regrind cam is of unknown specs and the rebuilder, Mike Richter of L&M Babbit did not remember (2005 as I remember) any specs or anything about where it came from.

I should say for those of you who may know Mike Richter that he did this engine in 1989. Really sad see such a nice and talented guy go down hill so fast! He built many very good babbit motors from 1966 until the early 2000s.

I also reinstalled the 160 thermostat I took out last week when the engine was overheating. Did not have time for a road test. Engine temperature went from 130 to 170.
