Want to replace carb on a 1974 1/2ton with 350cu don't know any other specs. Any shops have rebuilt ones on the shelf?

it should be a q-jet. they are easy to rebuild but if its a holley or a carter put a Q-jet back on it.

If there are no big problems with yours rebuild it. Rebuilt carbs you guy are junk.

the only thing i look for on a core is the throttle shaft bushing before rebuiding.......otherwise rebuild it urself with some help if u need it no prob...

and yes [iagree] the rebuild ones from the jobbers are junk never work right always warrantying them and such............

Damn. Its never that easy. I'm trying to do this over the phone. Its for an old farm truck. Was hoping all I had to do is grab something off the shelf here and then bring it up. When I call him how is he going to describe whether its a Q-jet, Holley or Carter?

Here is a pic of a Q-Jet. If you are going to order a rebuilt carb the PN is stamped on the drivers side back corner.

O.K. Thanx for the info. We'll figure this out yet. current problem is leak below the float bowl I think and very irregular idle. Sometimes rev's sometimes stalls. Pump is fine cuz at medium to full throttle runs fine under load and all.

needle and seat and a float will fix that.

A Q-Jet leaking under the float bowl? Never heard of that. :D
Heard of guys fixing it with seal-all. And as for the throttle shaft bushings, you can buy a reamer and replacement bushings to fix it. I bought mine through Snap-on at work, but I'm sure you can find a cheaper one out there.
