Cliff; The main problem is ;at a dead stop when I push down on the throttle it just bogs for a second or two and when it gets rolling it goes great !! That's about the only problem as of now . "CANNOT GET THE WHEELS TO TURN " LOL . I know , your going to say "no HP " Thanks for any suggestions .

garybohannon:
 Snaping open the front two barrels would normally depend on a good accelerator pump shot of fuel, to avoid bog... Like Cliff said.
 Snaping open all 4 barrels would require the vacuum diaphram to let the secondary flap open in a smooth, timed, movement. Shove the plunger in and hold it shut with your finger over the hole, then let go as you count off seconds.  2 seconds or more should work fine.
 Also very important is the amout of spring tension on the secondary flap. Try 3/4 of a turn tension setting on the flap spring.

Cliff Ruggles:
Verify accl pump shot with no delay anyplace.

What is the choke pull-off release time, and how much tension on the airdoor spring?.....Cliff

Been on vac a week or so and came back turned on the trusty ole computer and ZIP ; So after a few weeks I'm up and running with a new computer . The gas seems to flow good and the vacuum release is less than 2 sec, In the mean time I've changed the distributor out and made a couple adjustments to the carb and it's running better . I had a cheapie on the shelf that I purchased awhile back (Pro/comp) so I thought I might just aswell put it in and see if it helped .I set the timing at 12 and the advance screw in the vac adv, at 6 turns out. Not real sure how to set that properly . I had the other dist. set at arund 7 so it would start easier. Again ;I don't know why the old one would dtart so much harder at 12 and above . Right now it seems to run and start good but I can't help but think it should have better punch at take off. It may be all the better it gets as it's only a 76 350/308gear with a mild cam . It started out with like 165 hp as a 2brl .
