Lokar Alignment Problem

My 1936 coupe came with Lokar carb linkage to the footfeet...This car is new to me so be easy on me....I noticed the alignment going thru the firewall isnt exactly right and when accelarating the cable binds on the downside of the tube coming thru the firewall...a couple strands of cable are broken..to me it looks like when the accelerator is depressed the cable is slightly pulled down and catches on the bottom side of the tube...without redrilling holes is there something I can do to correct...I was thinking about some kind of angled washer or something to make that alignment better...thanks..craig

Hmm, I have LOKAR on the Nova but it goes out through the floor, under the pedal. Maybe you could remove the cable sheath and put a philips screwdriver the same size through the hole and push it down or lift up to bend the firewall face in the direction is has to go to make it a straight through shot? Just a thought.

I did something similar on my trans tunnel for the shift cable to go through at a shallow angle, worked great.

A call to Lokar would answer your question, but I will try to give you some help. It is important to get the cable pulling straight through the guides. Sounds as though the previous installer did a good job of that up at the carb bracket, but either drilled the firewall too high or installed the pedal assembly too low. To keep from redrilling, elongate the holes in the mounting base of the throttle pedal if you are talking a small amount. If it needs to go up more than a quarter inch, you will have to redrill the holes in the toe board to get it high enough. If you have already frayed the cable, then you might as well order a new cable and housing since the housing is worn into the wire coil and will continue to eat cables since it is impossible to get a perfect straight pull. When I install this system, I have the cable slightly high at the relaxed position, perfectly centered at the mid range position and it will be slightly low at the WOT position. The cable tension at idle is minimal at idle and gets higher as you move toward WOT. Since you don't spend a lot of time or not as frequent at WOT as idle to mid range, you get the longer lasting cable and housing by applying this theory.

I will call Lokar tommorrow and order a new cable assembly..at summit racing they are 42.95....I think my alignment is pretty minor and would opt towards elongating the two mounting holes for the accelerator....the accelerator would have to be raised about 1/8 of an inch...I thought the housing would have some kind of fitting at the end so this wouldnt be an issue...I'm not missing any parts am I?.....thanks again..craig...I'll post lokars commenst tomm...craig..

As Trees mentioned and just the way the carb bell cranks work - the top is cruise, the bottom the tranny kick down. The throttle is a solid linkage back to the pedal as I really ran out of room for that Lokar cable with the engine setback, but the principle is the same:

Called Lokar Today

They said about what I expected....relocate the foor pedal for better alignment...I moved it up about 1/8-1/4 an inch and at rest the cable is in the center of the hole...while running I looked at it and it doesnt travel very far when you accelerate so I think I'll leave it there....Lokar will be at our 50's event in a couple weeks so I'll buy a new cable from them...thanks again for your help craig
