OK got Bugsy back together from reinstalling a new manifold gasket and turned the key and he started right up. Fabulous, whoopee, unfortunately I think I've still got a manifold gasket leak under there. Carb I attempted to rebalance since I could visually see a huge difference in the way jets were set and height of the pistons. Back carb must have been set at 25 flats out in a previous attempt to overcome the manifold leak. Both are now set at twelve flats out and idle screws appear to be the same for both carbs.
I've got a problem and I haven't had time to diagnose and get into it yet.
Zero and I mean zero low end power. Having difficulty in getting engine to rev. Starts fine, depress gas stumble, stumble, stumble, will it rev, will it rev, hesitate, slowly, slowly slowly revs increase, hit 3000 rpm and all of a sudden rev quickly. I tried to take around the block and chug, chug, chug, vroom with some occasional backfires through the rear carb. Had to do a 4500 rpm start just to get back up my driveway into the garage. Yuck. Timing close, not that far off but car starts easily.Replaced all gaskets, cleaned up all surfaces and mating points, reassembled and figured I would have fun vroom, vroom time. Now I'm really puzzled.
Intake/exhaust manifold gasket was assembled dry per recommendations from this list. I replaced one manifold stud back exhaust manifold bolt. Was longer than the others but appeared to go into block so same number of threads were exposed. I will reassemble with two washers on it just to make sure I've not run out of threads to tighten.
Plan is to pull it all apart again, I'll assume I can reuse the paper/cardboard gasket and use Hylomar on both sides of intake manifold ports and all gasket surfaces and tighten back down to 15 foot./lbs once again.
At this point I'm looking for tips. 4,500 rpm starts will definitely shorten clutch life. Help!!!
