Holley Carburetor
01/30/11 at 17:55:41

Obviously not bike related but I was wondering if some of ya'll could help me out.

Does any one know what the stock jet sizes would be for a Holley 1850-2 carburetor? I bought a used carb from a pawn shop and was tearing it apart to rebuild when I noticed that who ever sold the carb to the pawn shop had taken the jets out.

As stated it is a Holley 1850-2 4bbl with vacuum secondaries. If anyone could help me out, I would greatly appreciate it.

I did do a search before I posted this and kept getting widely different sizes. But thank you.

Thanks, rebuilding the carb can easily be done inside where it is warm, the cold part is when I go to install it on my van's engine. I already have it all cleaned up so I don't have to worry about carb cleaner fumes. All I got to do is put it back together.

Holley carbs where all four holes are the same size won't normally replace a Q-jet without an adapter or aftermarket intake. You may need a Spread-bore style if you are replacing a Q-jet. HTH

HTH Cool

No problem, my intake is an Edelbrock Performer. Already test fitted it to the intake before I tore it down and it fits fine. Its going on a Chevy 305 V8 in an 83 Chevy G20 Van.

Just need to make a few very small adjustments. Also need a completely different air cleaner assembly. The one I have is an aftermarket that the previous owner had put on, but it won't clear the float bowls of the Holley.

Junk yard time!

IIRC, GM trucks with throttle body injection have a spacer under the air cleaner that should be what you need. Already has the ends flanged, may need a little massaging to fit.

I used one to make a 'cover' that smoothed the air flow into the carb in a class where I wasn't allowed to cut the choke tower off. Cool

Tech man never said a word, even though it defeated the idea behind their rule. Roll Eyes
