[DeTomaso] Throttle cable length problem

[Jeff Kimball]

FWIW. Amazingly, the Pantera throttle cable is almost identical to those used in many boats with Merc-cruiser and other out-drives.  When I needed a custom length cable for my Pantera I was able to get one from my local Mercury dealer in almost any length I needed.  

Of course your results may vary....

There needs to be X distance from the fixed mount to the pedal, and Y distance from the carb end mount to the carb. Within broad parameters, both measurements are critical. If the total excess length of the inner cable compared to the sheath is too long, you won’t be able to open the carb, and if too short, the cable won’t reach both the pedal and the carb. Sounds like that is the situation you now face.

I have talked to the vendor and he told me he made his assembly longer (about two inches) than the stock assembly and said this was done due to the tight radius problem. ??? To me that doesn’t seem to offer much of a solution as the curve the cable takes is still more or less the same.
