Carter problem
Ok, My brother just switched to a '66 carter 4-barrel on his '66 Catalina 389 and it has a flat spot under light acceleration. Someone had said it might be the accelerator pump but I don't think so because you can hold it at the point where it stutters and it will keep stuttering. I tried putting new jets (edelbrock #1426 .095 orifice) in it and forgot to put the rods in and it ran good but when I put the rods (edelbrock #1455 7042) in it was back to stuttering. The step-up springs are edelbrock silver 8-in. Hg.Gerig Michael H.

Yeah, I had already been there. But the kit that I had bought only had 3 rods 3 jets and 4 step-up springs so I'm trying to get an idea of what range of rods & jets I need to getGerig Michael H.

I have had great sucess w/Carter(Edelbeock) carbs. I have bought around 25 from Summit. I buy the one w/a electric choke.
Good luck....Don Meyer, PhD-Mech Engr(48 GMC Trk/chopped/cab extended/caddy fins & a GM converted Rolls Royce Silver Shadow).

It's been a few years since I last worked on a Carter, but if I'm not misstaken the metering rods primary purpose is to restrict fuel through the primary jets at idle. To me that would indicate that your primary jets are too small or the metering rods are too big. If the motor has a healthy cam it will add to your problems.Ken Thomas

Gerig, if you'll do what I suggested you do in the first place, your problem will be solved. Go to the owner's manual and read "Calibrating the power mode staging". It describes exactly the problem you're having and the fix for it.Gerig Michael H.

If I could I would but he just got it painted (which reminds me. I'll post pics. in another post) and we haven't gathered anything to sell as I'm 16 and haven't had time to really get a collection of parts and we have moved twice in the last 10 months so I have already had to get rid of stuff that I had gotten.Gerig Michael H.

Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
