I have now plugged the unused holes in the adapter plate for the Howell TBI.
My vacuum at idle went from 17 to 19 and #2 and #3 cancel out as they
should. Next step is test drive. Hopefully today. Will report results.

Runs better now but still not all it should be. Found the wrong gasket
between the TBI adapter plate and intake manifold. It too was causing
vacuum leak. Replaced with correct gasket and no more leaks. Runs much
better now with no miss. Vacuum still pulls down on acceleration lower that
I like(4" or so) but Mr. C. says his does the same thing. Maybe that it
normal with TBI. Vacuum is about 12 on flat road at 60 mph. Guess I'll
live with it.
Now on to other things---drop fuel tanks and replace lines!!! This should
be FUN!!!!
