Guide to carbs

I may be soon going thru a Holley 1920 carb, Not sure where I am going to get the carb kit from, alot of choices and I have asked on-line about a Ethanol friendly kit without much response.

Before I go thru it Id like to read something that gives me a better idea of things I should be looking for as I am going thru the re-build process.

I have read alot on-line that for instance such items as the idle mixture screw being turned all the way in and all the way out just doesnt affect idle any longer due to something internally worn out ( I am guessing ) in the carb.

Evidently people overtighten the screw and mess up the seat. Evidently from what I have read this is pretty common and once it has happened the carb is junk.

Another good example would be the ( possible ) warped float cover I have an issue with now. From what I have read placing the cover on a flat piece of glass and gently trying to rock it back and forth is a way to determine if the cover is warped.

I have read a few somewhat vague posts on how to correct this issue but would like to read something more specific.

I would never have known this unless I stumbled upon a thread on-line that mentioned it.

What other potential problems might I be faced with?

I am pretty sure these kits do not come with any fix for some of these issues so why try and re-build a carb that may have issues that cannot be resolved.

How would one check for things while in the re-building process unless he were aware of the possible issues?

I am reading about some potential issues like mentioned above but a quick reference guide specific to these Chrysler 1 barrel carbs and 2 barrel BBDs would be nice to see.

A guide to re-building a common Holley 4 barrel is not going to do me much good I do not believe.


Having something like this ahead of time would really save people alot of headache.

Does anyone know of such a guide?
