You can do most of the accelerator pump tuning in your driveway.  Just push the throttle wide open and take note of how the engine behaves.  If it stumbles, you need a larger squirter.  If there is black smoke out the tail pipe, you need a smaller squirter.  If it picks up rpm cleanly, with no stumble or smoke then it is pretty close and you're ready for a test drive to verify under load.

What are U setting the initial Timing at? Is the Vacuum Advance ported or non ported( full time Vacuum)? Using the Timing Light Is the Timing advancing steadily as RPM increases?

  

I believe timing is at 8 - 10 kind of hard to tell as marks are hard to read.  Right now am going off the carb port for dist. vacuum. And as idle speed increases timing mark increases . Accelerator pump system check out ok. Vacuum gage show needs timing. Placed the plastic accelerator cam in #2 spot , will check timing again and take for test drive, later today.
The spring in vacuum diaphragm is the stock silver has anyone had to change it up or down?
What would be suggested to the timing? I believe my info show 2 for manual and 6 for automatic.

Well you all came through again! Everything is falling into place and she start runs good in garage. Could not have done it without y blocker help! Most of my issues were caused by me but you all got me through it.
Now have Mother Nature causing problems RAIN and RAIN. The weather here has been crazy have had few day that getting car out test driving. But hopefully this will pass and I can do test drive. But feel I should be very close to thr right tune. Thanks again to all!

Today Sun shined and so did the y block. Still a little fine tuning but thanks for all you help I could not have got to this point.
