Need ure help on this one, im gonna rebuild an old carburator, but the number has been grinded away. So I have no idea what rebuild kit to buy=(

What I know or think I know is this; prolly 600cfm, 4barrel, mech secondaries side hung floats.

Holley 600 vac secondary. The choke horn was 'CUT' off....and the vac secondary part isn't even there. If it was a mech 2ndary then you'd have a 2nd pumper pot like on the front bowl, but on the rear bowl.

That carb looks like a parts donor to me in that shape...ehhhkkk

Ok, well. Ive cleaned it up with diesel and polished it some, looks pretty nice now.
Think it looks worse then it is because the valve cover ventilation tubes where drawn behind the carb!!?

hmm, will it run like crap when I miss one of the pumps? like bog down when I give it full throttle?

Looks like some junk ive tried!
just rebuild her and if it doesn't run after somone here can help you!

Yep that's an 0-1850 vacuum secondary carb. Someone removed the vac. sec. pod and stuck a screw in the other side to make it appear to be a mech. secondary. Time to order a vac. secondary pod, and remove that screw!

thanx guys!

i have run into this before. if you measure the throttle blades you can then compare them with another carb. and yes this carb will have a big bog when the secondarys oper due to lack of initial fuel. i use a mill to remove the choke horns and then stamp the pn# back on the carb for future referance.
