I am helping yet another friend today with his 58 Plymouth "Christine" Replica. When I went to help him out the last time, his damper lost all the paint and there was no groove for a timing reference. I pointed out to him that he needed a kickdown linkage as the guy who put the engine together for him, neglected to install this vital component. We finally got the Bouchillon kit after a month back order...what a PITA to install it...I have done the one on my Charger and I was done in an hour...it took me 4 hours UNDER the car alone.

Anyways, The underside is installed, the top side is installed but it needs a modification still to have the right geometry. The problem here is, the pedal was "designed" by whom I have no idea...that you accelerate by pushing forward. Is this how they did it back in the 50s? He had a holley 800on there and it was puking fuel everywhere so I installed my old 750 which works. I installed the kickdown bracket on the carb from Bouchillon but I installed it to PULL the carb to accelerate....the pedal was on the floor...so I redirected it to the top of the 1481 bracket so it PUSHES the carb open but there is alot of resistance and I KNOW it isn't supposed to operate this way.

What can I do to help this guy out...He is the owner of this car club but no one wants to touch his car and I am pretty much the only one knowledgeable enough to tackle it. Two pics coming up

Try some lighter return springs. Those things are monsters for the set up your're doing.

I disconnected them in one of my many attempts...its as if the pivot point in the bracket on the carburetor is providing all the resistance...The gas pedal sits half way up with this setup...

How was it back in the Late 50s...was it a push method or a pull method. I have really ony worked on cars with the throttle cable attached to the throttle bracket via the intake manifold....never a bell crank to the pedal

those old mopars had a mechanical push system for the throttle.

Options,see if the under the dash mounting can be reversed to make it a pull system,make a longer lever to allow more leverage for the push rod to work the carb linkage.Putting a spring on the throttle to remove some of the spring pressure all ready built into the carb spring,but not enough to cause the carb to hang open.mrmopartech

The pedal, from what I saw...goes through the floor board with a solid linkage...to a bellcrank....and the forward movement is all with shafts. I wish I could put a cable on this setup and be done with it...its so easy....I may have to pull rank, get a 69 B-Body pedal and hammer and run a cable to the carb...

Or just use lighter springs on the return.

Id get 1 of these http://www.summitracing.com/parts/edl-1481
and find a normal/simple pedal/cable system from almost any Mopar...
