I am having a tough time finding a rebuild kit for my Holley 4779. Doesn’t seem to come up when I search jegs.
Clink on the Service Parts tab on this link. You will see the kit.
Holley 0-4779S 750 CFM Double Pumper Carburetor
Mine is a -2 instead of an S. Will that make a difference?
Here's a thought..........call Holley and see what they have to say..........they could tell you what the difference between a 4779S and a 4779-2 is and help you get the kit you are looking for. Just a thought.
That makes too much sense.
I'm just crazy like that......................
Holley used to have a section that listed all the stock jetting/squiter sizes for each specific list # that was useful for fixing "fixed" ones. I don't know if that still out there either.Exactly.
But so you know, with Holley,
Model references a general design.
List is the specific version.
- is the revision.
Underneath that may be a date code.
Holley does offer a Carb List with suggested rebuild kit #s.

A good way to see the differences between the various kits is to hunt down the catalog. They keep moving it so I'm not going to offer a url since the ones I've bookmarked are probably all dead. But its out there somewhere in pdf or page flip format. My recollection is the "Trick Kit" has a lot of extras and is worth it if you plan on a lot of tuning and trying different combos. For super basic, clean and go, really just need bowl and metering block gaskets, along with umbrella check valves and pump diaphrams. (Your carb is early enough it may not use the umbrella check valves).
Also a good investment is one Mike Urich's books on Holleys - the general one or the little one on 4150s. You can usually buy them used for cheap.
Yup, they're on the Carb list pdf linked above.Holley used to have a section that listed all the stock jetting/squiter sizes for each specific list # that was useful for fixing "fixed" ones. I don't know if that still out there either.
