|jaw22w||Update: I jetted the carb up to 76 on the primary and changed the primary nozzle from .035 to .040. It was nice out today, so I took the roadster for a ride. These changes got rid of the hesitation and the bucking or surging. Don't know which change helped, but the car runs like a raped ape now. Again, thanks to Cobalt327 and Custom10 for all the help. I am very happy with the results.|

|jaw22w||Custom10, I brought up the vac adv question because White performance told me not to use it. I wanted some confirmation from some of the expertise I knew was on this forum. I have always run my circle track race motors at 34* total with no vac adv and the advance numbers seemed very high to me with vac adv. This new motor was a large investment for me and I didn't want to burn it up. I have seen the results of too much timing in race motors. UGLY!|

It's late. I'm going to bed. Just wanted to say that I cannot express my appreciation for all the time Cobalt327 and Custom10 have put in on my problems today. Thanks for your patience with me.

Cobalt327, OK I think I got it. I just scanned the Holley instructions. They definitely deserve a good read.

Edit- just saw you figured it out.
Pump free play at WOT:
Basically, you want zero play at rest, foot off the gas pedal.
With the throttle opened wide open, there has to be about 0.015" play so the pump diaphragm isn't damaged from the linkage over-traveling.
The adjustment is made using the small bolt/spring that contacts the pump arm and a feeler gauge (see below). This photo is one that shows the feeler, etc. good, but the adjustment bolt and nut are upside down plus don't look to be original (shouldn't be slotted). Assembled correctly, the adjuster nut, bolt, and spring should look like the second photo.
Holley's instructions on the shooter and cam are on page 6 and 7, here.

|jaw22w||the adjustment bolt is between the upturned end of the rod and the can. The bolt is parallel to the long portion of the vacuum rod. As the vacuum comes in and the upturned end of the rod moves toward the can, the bolt contacts the upturned end of the rod and stops its movement, thus limiting the amount of advance. I hope this makes sense. I have attempted to post a picture, but was unsuccesful. I will work on it.|
