Six Pack issues and rebuilding by tommyg29

so the float bowl screws identify old/new style? Didnt know that. Guy claims new original stock. Dont know exactly what that means  

Not caring about originality, do you know the pros and cons of old vs. new style?

Ive heard issues about the repros. Still made by Holley but not as good for some reason?

Screws or bolts doesnt really matter to me. I could always buy replacement bowl screws. Anything I should be aware of with the "new" six packs? For now I would just replace the outboards.... maybe down the road look to replace the main.

Kind of changing the subject here, but its kind of morphing into a "what should I do with my 40 year old carbs" topic.

If I do upgrade, maybe go new, swap the promax meter plates and sell my old stuff to someone who can use them for parts or try to bring them back to life?

Anytime you have three times more of anything youre probably 3X more likely to have a problem or something break, so in that sense they may have more issues, but generally I think once you have them tuned, and dont mess with them, they should give years of good service.

And dont know about the sixties, but anything 40 years old will tend to have more problems too.

Been almost a month and now Im back. Spent some time on vacation out of the country, home repairs, etc, and decided to pick up a used full set of the correct coded carbs for a 71 off ebay. Spent the past few evenings pulling my existing carbs apart, AGAIN!, and removing the rebuild gaskets and parts to transfer them to the used set I picked up. I can do it now pretty easily without looking at diagrams or instructions, but.... its still time consuming... cleaning all the orifices, carefully scraping off and cleaning mating surfaces, etc. The tricky part is using the right gaskets. All I can do is use gaskets that are identical to the ones I remove, but that assumes of course the right ones were installed in the first place. Big assumption.

I am also scavenging a couple small parts off my original set to put them on the purchased set. A couple parts were missing, or didnt appear in as good a condition, but overall the new set appears in better condition.

Having a couple issues though. For instance the hot idle compensator cover didnt seem to fit tightly so I filed it down a little to make a tight fit. None of the exploded diagrams ANYWHERE show this rear part!  : Why?!

There was a FANTASTIC article about 6 pack rebuilding with great pictures I was using last month but the site has disappeared since?  The site was: Winged Warriors/National B body Owners Association.

swear:  

Another issue... proper gaskets for the discharge nozzle screw... I think i got it right.

Here is a list of List/model numbers
