Throttle Linkage

(1/3) > >>

lake_harley:
I've been rolling a few thought around in my head about throttle linkage. I want it to be constructed to be rod linkage so with a toe loop on the pedal the throttle can be returned to idle positively in case a return spring fails. The engine will have a single carburetor and I've been doodling various linkage arrangements, trying to work out the throttle pedal travel and position to travel of the linkage on the carb. Lots of balls in the air when working out the geometry. My head hurts already.

Just to have some clarity, does anyone have the body off of their FED to take a photo or two of your throttle linkage arrangement? Posting photos here can be a challenge (to me at least) so you could e-mail or text them to me at the e-mail address or number below.

Thanks....in advance!

I'm no help with pictures, but you can use a morse cable and it will also allow you to pull the throttle shut in event of a return spring failure. On my car the cable just loops around from the pedal and up in front of the engine. Pust the carb on backwards and cable pulls from the front of the motor. Works smooth as silk and was very simple to setup 

lake_harley:
So you're saying "push" to open the throttle and "pull" to close? Pull to close would certainly be more positive and foolproof when it's needed. I may be able to modify the primary linkage for that operation. Hmmm.

I use a Morse cable for throttle also.
I have a return spring on my gas pedal and 2 more on my hat/injection .

Finnish Fireball:
Morse cable here as well, loops from front to back. As said above this forces your carb backwards. I have twin carb side saddle setup on my blower, and the linkage/cable combo was pretty challenging to get working properly.
