BUT, fabbing a 'PULL' vs push throttle rod is not panning out. Issue is the huge curved recess in the firewall is right where my new pedal assy needs to be.
I've seen set ups using the original rod to a bracket for a flex cable, mounted where the bell crank was but it's behind the exhaust and very tight place to have to work.
Any ideas would be appreciated. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | Not sure if this will help but this is what I did to put a pull throttle cable to my 4 barrel in the 52 panel.
I took a 3/4" wood dowel and cut some pieces at different angles to get it to fit the recess and be "flat" where the cable comes out. I can't remember the angle but once you get it then you can cut the piece that goes through the firewall depending on the type cable you use. I use a Lokar pull cable/pedal ect.
....did any of this make any sense to you? | | | | | Joined: Feb 2004 Posts: 29,850 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,850 | Install a gas pedal long enough to pivot it a little below center with a strap hinge, and attach the cable to the bottom of the pedal. By tinkering with the pivot point and the attachment to the carb bellcrank you can alter the speed and distance of the cable movement. We made race car throttle pedals this way. An added benefit is that it's possible to close the throttle by pushing the bottom of the pedal with your heel if you use a push-pull cable like the type used for a PTO.

I'm going to keep the stock pedal and throttle rod but eliminate the bellcrank. I'll attach a short, vertically mounted length of angle to the boss just under the aft freeze plug and run the throttle rod through that. The tip of the rod will be bent upward forward of this plate to attach to my cable which will be pointing aft. Cable will loop around and up to the carb.
I saw a set up like this years back so will see how this goes. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | Be sure to take and post a couple pictures.
