Have hooked up the Offy linkage kit I bought from Tom Langdon to my two Holley Webers. First had a problem with the crank arms trying to rotate around the shaft. Ground a little off of those where the bolt and nut crank down to get them a bit tighter. Now, with everything hooked up, when I step on my gas pedal, I only have about 1 or 2 inches of pedal travel before the carbs are at full throttle. Am I missing something in the way I set the linkage up? Would like a bit more pedal so I don't go from 0 to 60 instantly.
