Hi List: My 74B is running pretty well now thanks to all of you. However,
there are four threaded holes (7/16 by 20 pitch) located just above the spark
plugs but below the top of the block.
When I shut the engine down, I see "wisps" of white smoke coming out of these
holes.
Are there threaded plugs that should go in these openings?
I have tried to see if so from photos in my books, but cannot determine if
they are there or not.
Will one of you identify these openings and tell me what I should do about
them. My parts books do not identify.
Thanks
Dennis
