need more throttle travel

So I have a 600 eddy 1406. I was looking at how far my secondaries were opening and it was only a little, maybe 1/8 of the way. I thought it might be the kickdown linkage binding but after taking it off it still was the same. So I loosened the throttle cable clamp and pulled the cable back more to get another 1/4 in of pull or so and then it opens the secondaries all the way but won't let it fully return to the idle stop screw so it idles high. So how do you get more travel all together?

I have the mopar bracket and am using the larger hole that the factory pin fits in for the kickdown/throttle connection. Seems like running a drill through the smaller hole in the bracket and using it might give more travel as it is closer to the pivit point on the shaft of the carb. Or is there a way to bend the pedal itself to get more travel?

I'll put the kickdown back on once I get this in a full range, but for now it's just locked into about 3/4 throttle pulled back posisition not attached to the carb so it's not a factor.

I was thinking it had nice power before but know wonder how full secondaries might feel LOL!


You can't add more travel to the cable. It is simply stroke at the pedal (input) is directly related to movement at the carb (output). The cables are only designed to handle so much travel and then bottom out.

The only other way to "fudge" it is to lower the pivot where the throttle stud goes to the bracket (move it closer to the pivot) to get more stroke at the carburetor (modifying the ratio of input to output).
