Is this carb hook up correctly?

Well, as I understand it, the 1920 is a lot simpler. You might try rebuilding it again in case you misread some of the instructions or dropped a tiny little part (like I have). Might also find help over on slantsix.org, there are folks that post there that are using Holley carbs. I would try a google search for the particular carb that you have, by model number. There is often a bunch of good info, tuning tips and the like listed. I'm surprised there have been no knowledgeable Holley users replying here.

A google search for "Holley 1920" gives several hits, if you want to try yours again. And google search for "Holley 1945" does too. There are a couple of 1945s on ebay right now, if that's another approach you might want to try. Or, I have a newly rebuilt 1945 that I will put in the parts for sale forum here, as I understand we're not supposed to mention that subject in this forum.


Wish I could be more help.
