[my289]

67 289 engine. So I had been fighting getting my carb to open up all the way. I thought it was under the hood and I tried adjusting the throttle linkage in and out but that would raise my idle and it still would not open the throttle all the way. Still needed like another 1/2" to be fully open. I found that inside the accelerator pedal to the ground was only like 2-2.5" inch travel which no matter what I would do under the hood it would not open the carb all the way. What I ended up doing is disconnecting the linkage to the carb and then I lifted the accelerator pedal inside (good hard tug) and that gave me another 2 inches of travel. Now my carb opens up all the way and still have 1/2" before the accelerator pedal is on the ground. Is it ok to do this? Or maybe after 53 years the whole accelerator pedal assembly is tweaked? How much travel do folks have from the bottom of the pedal to the floor?

 

[64-1/2 first.... 66 now]

Basically 0'', on the floor at full throttle so you're not putting excessive lateral pull on the throttle shaft.

So far is your accelerator pedal from the floor when turned off, how much space do you have to push it down? I am pretty sure its going to be more then the 2-2.5" in I had?

I had to bend my pedal arm inside the car to get WOT.

I just had this problem too!

Throttle linkage not opening the carb all the way

Does anyone else have an issue with a mechanical secondary not pulling all the way open? Below is my setup. The big hole on the linkage and current setup fall just short of opening all the way. The lower hole on the carb linkage make the gas pedal unbearably hard to push. The factory throttle...
