It was on the 79 chevy 4x4 stepside p/u when i bought it along with street dominator intake. Engine was blown up so i bought a 90 chevy motorhome and put the engine in the truck. But I have been out of the modified older car/truck game for so long now I dont have the resources I had for used parts. Most of my buddys I used to work on this stuff with have passed on or just too old to remember stuff like that. I have rebuilt tons of old carbs Rochester/ quadrajets but everyone told me to stay away from the older holleys cause they were so finikie. This is the first one. I will hopefully be able to get a chance to work on it tomorrow, If I can figure out how to post video on you tube and put up a link of her running I will. Thanks again guys!

I've always had really good luck with the old Holleys.. simple and easy to work on and adjust... only thing they don't like is sitting and not being used.. the gaskets tend to dry out and they will leak.. keep us posted

I found the little buggers. Thanks for the info guys!
Should probably go get my eyes checked the things were right on the instructions sheet under my nose!

Sure I have. But I found the answer in the parts diagram just like you did. I've also had to put things back together that came to me in pieces.... taken apart by someone who couldn't put it back together.

I would have rebuilt it. I don't think your being cheap. I would have thought it silly to replace the carb when all it needed was rebuilt. That would have been a waste of money.

Glad you figured it out.

I like Holley's. But I have to agree with George about the Carter AFB's (Edlebrock) being the simplest carbs on earth. You can't go wrong with them. As others have said, Holley's don't like to sit. If you don't run them regularly, they leak.

I rebuilt a 4 barrel just like yours yesterday, the model was a 1850-2, electric choke. And I had a parts carb that was a model 1850-4, manual choke.

It was a pretty simple rebuild I am going to mount it today to see how it works. Going on a 350 chev in a demo truck.

I got the kit from Napa and if I find the part number ill post what it is.

If you have an old Holley with the original or even some replacement gaskets in it, you can expect it to leak because the gaskets have shrunk. Even if they don't leak or stop leaking, you likely will have probelms because the metering block gaskets have shrunk and blocked some passages.

When they leak, some ham fist comes along and cranks down on the bowl screws thinking he will stop the leaks. He won't but he will succeed in warping the metering and main bodies of the carb and then all you have is a pile of junk unless you can press the parts back in shape in a jig.

The biggest enemy I have seen to a Holley carb is what I just decsribed. Fortunately, today you can buy gaskets that don't shrink, don't leak after sitting dry and idle.
