Thanks Dan,

That seems to be the general opinion of the group, so I'm
starting to feel much better now, and I guess I need to start
on those carbs tomorrow.

Thanks again,
                             Alan B.'

If my limited mechanical knowledge serves me correctly:
Black = fuel (too much), timing or both
White = water (head gasket)
Bluish white = oil burning (bad rings,etc.)
(tell me if I'm wrong here, folks, cuz I'd enjoy the education)
So I'd check those carbs first! The compression #s aren't that bad. Mine   
much lower(bad head), but the other components are in good order so the   
runs pretty good, just not as much hp as it could have.
Hope this helps.
