Accelerator linkage
1936 Model 68. The linkage from the accelerator linkage on firewall that connects to carb is too long and has been bent in a curve to compensate by previous owner. Ordered a 10.5 “ and it’s about 1.5” too long. Does 8.5” sound standard? According to what I’ve read 10.5” is standard. Do I need to make one or is something maybe not right at the firewall?… Greg

Re: Accelerator linkage
Needs a shorter rod that fits. Or the linkage on the firewall is bent.

Re: Accelerator linkage
I was trying to see if the linkage at the firewall on yours is all parallel but the glare from your shining paint is prohibiting me.

Re: Accelerator linkage
If ok, cut the long rod to size, thread the ends and make a little turnbuckle to adjust. You can see the aluminum turnbuckle in the photo. Both ends of the turn buckle are RH threads with a dab of Locktite, if needed.
This is an 8BA in a 40 but, idea will also work for you. |

Re: Accelerator linkage
Need a much better pic of your engine. Maybe your carb is a 97, not sure. Maybe your firewall linkage is out of position or bent from its standard position. Post better pics please. Regards, Kevin.

Re: Accelerator linkage
Here is a summary of throttle rod lengths compiled from drawings at The Benson Ford Research Center.

Re: Accelerator linkage
Here is how its supposed to look.Although the car is a '33 the engine is a 36 w/34 intake and 97 carb.Disregard the hose lying on the intake in front of the fuel pum.

Re: Accelerator linkage
Trying to find specs of linkage length from pedal to pivot at firewall, looks too long. Waiting on a second set of eyes, sucks when you can’t see both sides of firewall at same time. Here are better pictures.

Re: Accelerator linkage
Defiantly too long.

Re: Accelerator linkage
The rod should be longer than the measurement between balls as they now sit so that there is pressure keeping the throttle closed.

Re: Accelerator linkage
I had a similar problem so, I cut it to fit & covered the weld with shrink tube. Paint the rod black. works just fine & looks OK.

Re: Accelerator linkage
It will definitely have pressure on it, I can’t snap ends on by hand I may use pliers and a little force and quit over thinking it. Gotta have a bigger hammer! …. Greg in Tennessee

Re: Accelerator linkage
Those ends should snap on with very little effort.

Re: Accelerator linkage
To be clear, the linkage ends will snap easily onto the ball ends of carb or pedal linkage, just have to put so much backward force on the pedal ball end after connecting to carb I can tell something isn't quite right.

Re: Accelerator linkage
That arm is spring loaded. Any play on the inside floor pedal linkage?
