Carburetor Linkage Issues
Hey all,
I own a 1971 Ford F-250 Custom that I'm currently working on, and I'm having a load of issues with my carburetor linkage.
It is extremely fragile. Half of the time when trying to start my truck, it will break, and I will have to affix a new one to get going.
It drives me insane. When I'm trying to fix starter issues, I have to halt all progress to fix the carburetor linkage.
I've gone through too many, and am looking for help now.
Do you guys know where to find a good quality carburetor linkage (that won't break when I use the throttle), or any solutions to make sure it doesn't break?
Any feedback is appreciated!

Welcome to FTE.
OEM throttle linkage is pretty strong stuff. Is this OEM linkage?
Is your linkage adjusted so that when the pedal is on the floor, the throttle blades are wide open? If you are wide open before the pedal is floored, you will have a lot of stress on things.
Is it cable linkage or rods?

It is the rods.
Also, thank you for the link. The diagram on that page (http://www.fordification.com/tech/im...elinkage01.jpg) shows the part that is breaking, #9826.
I will check how the throttle is adjusted when I am able to as well.

I know what the problem is. What size is the engine, which trans does it have?

1967/72 F100/350's with V8 engines have a bellcrank that bolts to the rear of the intake manifold, the carburetor rods attach to it.
The problem is that the bellcrank has nylon bushings that crack apart, they cannot be replaced by themselves, so...when this occurs, the carb rods flop around.
D0TZ-7A185-A .. Bellcrank / Obsolete
1970/72 F100/350 360/390.
NOS PARTS SOURCE in Olathe KS has 1 = 913-220-5746.
MILLER OBSOLETE PARTS in Binghamton NY has 2 = 607-722-5371.

NOS PARTS LTD in Waxahachie TX has 4 = 972-937-2201.

Yes, it goes by several different names on different distributors, most call it a carburetor linkage, so that's what I call it.

It's just a spring retaining clip. who ever told you it's linkage doesn't know what they are talking about. Those clips come in left /right and different diameters. If you find the correct one your problem will probably go away. At most part stores you can buy a package with an assortment of them..

My parts catalogs don't go back that far, but if this is the clip you're looking for (C7TZ-9826-A), Green Sales in Cincinnati, OH has 182 of them (800) 543-4959.
I would also take a long hard look at the rest of your linkage. It sounds like there are other issues going on. Usually these clips are pretty trouble free.
