Isn't there a vac secondary Holley that has idle mixture screws that operate backwards?
Perhaps a smog model?

i dont know for sure about that denny.... but i do know that i've found plenty of them on 390 fords.... but it does sound like something chrysler would do, they're always trying to be backwards on things

Backwards? Depends on your perspective i suppose........

ya know like left handed lug nuts i've seen quite a few lube techs break studs on those trucks

You're right.........no excuse for that one.

got the carb done last night, on the older holleys the acc. pump goes through the metering block into the main body with a brass shaft with o-rings on the end, the o rings were bad leaking fuel into the power valve, so thats where my stammer was I think, fired up alot easier and not having to crank up the throttle plates to get it to run, so step in the right direction but still have a miss and but alot more steady vac. holding 15 to 16 minor fluctuations now bout 1 ever 2 seconds, so major improvement. Heres what else I found, take a small vac line off the vac advance and the vac increases to 18 and holds steady with a vac leak! More vacum with an open line. weird to me. Also with the throttle open to about 2500 I can hear minor poping back through the carb, so thats my miss and why it dosent run good, so i think the carb issues are done so I guess I will try to pop the valve covers off and see whats next! Starting to sound like a valve not opening or closing all the way. But on a positive note she did start right up and didnt shake like she used to so making progress.
