Chris - since you have the electronic whizbang, have you upgraded to an alternator?

We have had lots of customers with "carburetor idle issues" and a ew with no alternator. The generator does not provide a significantly stable voltage at idle. Generally, the problem (running rich) goes away when the engine gets above maybe a 1000 RPM.

Jon.

Interesting that this has come up. I was just searching for a w-1. You mentioned that the truck hasn't been run much, so some of the issue may be that it needs to be on the road a little more. The compression check will tell you some good things and most likely ease your mind some on the previous owners rebuild. I am a died in the wool fan of the carter YF. It solved many of my issues with the rochester -b. They have suddenly become a lot more expensive on e-bay though.

Chris, NICE truck with all the great original sounds. After watching your vid and reading the above I've no doubt you'll have it all properly sorted very soon. We have many knowledgeable gentlemen here that give good advise. The only thing I'd change on your truck (aside from the fuel pump and perhaps carb) is the air cleaner. I personally like the original oil bath units, either converted to paper filters or just leave em totally original. But, lots of options to get a larger/better filter on your truck.

Good Luck,
RonR

Hi Chris,
Different Jon here. If you want to see the work/study on the warped Rochester castings, you might search using "straightening Rochester castings". Based on what I saw, every Rochester B or BC will have a warped casting to one degree or another. There is also some information on the power circuit/power piston and the problems caused by loss of vacuum, inadequate vacuum, etc to that part of the carburetor and the effect it will have on the rich/lean condition.

The Carter I'm using on my 235 does run much leaner and more well mannered than the Rochester did by the way.

Anyone use a Carter carb on a 261? Thoughts?

Carter was the original equipment carb on Chevy engines for a long time until GM started to build their own carburetors in the early 1950's. I believe a Carter YF for a 258 cubic inch International/AMC/Jeep 6 cylinder engine would be just about perfect for a 261, or maybe the same carb set up for a 300 cubic inch Ford six, which would run slightly leaner than the AMC carb when used on a 261.
