I have got the solution on my problem. I don't need to cut the rod, because I found a rod with the length 10-3/8 which is the right one for my application. Thank you everybody for trying to help me to find the solution.

40cpe, you gave me a clue. I have checked the butterfly shaft position before and did it again. The distance from the firewall is the same but the bulb on the butterfly shaft has a higher position on the Stromberg carb. That means that the carbs need different length of accelerator rods. See attached photo.

You have both carburetors there in front of you. Put them side by side and compare the attachment point for the rod end with each other. Are they the same in relation to the butterfly shaft? Is one attachment point closer to the rear of the engine than the other one? The carburetors bolt in the same place, so the butterfly shaft should be in the same place on both.

40cpe, you got the point. I apologize about my bad english but that's just what i mean. Why does the 10.5 rod fit on the Stromberg carb but not on the model 59 Ford carb?

On 10/19 he said "My explanation about the idle rpm was not so good. What I should say is if I connect the rod to the carb the throttle get open without touching the accelerator pedal." Maybe what he is saying is that the rod being too long causes the accelerator pedal to be closer to the floor. Or maybe the idle screw is set too high on the 59 carburetor. It seems his real concern is why the rod fits one carburetor and not the other.

Jehn, your description is backwards of what should happen. The extra pressure on the throttle lever will keep the throttle lever at the idle speed adjustment screw. In the attached drawing, the blue outlines the linkage and the red arrows show the direction that the rod goes when the pedal is depressed. Is your linkage like the drawing? If it is not, could you please attach a photo of where the rod is connected to the accelerator shaft, showing as much of the accelerator shaft as possible.

The rod with the length of 10.5" (266 mm) will do too much pressure on the throttle without touching the accelerator pedal. Of course I can bend or short the rod to get the right length but why does it not work? As I know is there just two rods like these on the market, 10.5 and 10.75 and none of them seems to fit my application.

Are you saying that the car idles normally with the rod not connected, but idles too high with it connected?

When you press on the accelerator pedal, the rod should travel towards the rear of the car, pulling the throttle open. When you release tension on the pedal, the rod should travel to the front of the car applying pressure to close the throttle. If you look at your photo, you will see that rod travel towards the front of the car will close the throttle.
