MTFCA Forum

Is anyone using a Williams Accelerator? I have seen posts on the forum but never one installed on a car. I picked up a complete Williams Accelerator several years ago and decided to install it on my speedster. I have a three speed Warford and have heard it is much easier to use with a foot throttle.

Having only the advertisement to go on. Installed it as show on the picture. After hooking up the pedal, it seems the cable is too short. Using the sliding connection attached to the carburetor, the cable for the foot pedal goes through the center of the block and wraps around the back of the engine. With the pedal at rest, the cable is pulling the carburetor lever to about 1/4 open and is binding when depressing the throttle.

I thought about reversing the throttle rod ends so the cable goes along the passenger side of the engine but wanted to see if anyone on the forum has advice.

Thank you,
Dan

Found this ad. A picture is worth a 1000 words (change your connection). Thanks for the question, I have a pedal now I now what parts I need to make it functional. Also looks like the "rod" can be adapted to any pedal using a throttle cable like used on a lawn mower or choke

May need this for to simplify the install

Somehow, the cable housing needs to be anchored at the carburetor end. With that taken care of the cable can be pulled through the housing. It is the same deal as the choke cable on an OF. The cable housing is captive at the carburetor. Perhaps I an missing something.

The cable housing is anchored on the throttle rod.
The neat thing about these kind of contraptions is the foot throttle overrides the hand throttle rod.
Set the speed on the quadrant. accelerate with the foot. When you back off the foot throttle, speed resumes to the hand setting.
Great for shifting a rux.
OP's pictures dont show the cable wire clearly to my eyes. However, the ads show the correct setup clearly.

Does this help the eyes

Pretty sure the cable housing is anchored at both ends, at the foot feed and locked in the copper piece on the throttle rod. Once installed, the length of the cable housing can't really change between the two parts so just lets the cable move without moving the cable housing. For using the hand throttle, the rod slides in the copper piece. When using the hand throttle, the foot feed will go down without pressing on it. Guessing the foot feed had a set screw to hold the housing in place at that end. Think kinda like the hand brakes on the bicycle, only the cable housing is lock in place.
