bzt, I think you hit the nail on the head. That's about the best reason they could have left
the had throttle on the trucks. And as Chris mentioned, I've always though it was a throw
over from the days before they had carbs with fast idle cams and I'm sure it was used for
that.
I can only think that using it as a cruise control would be akin to lighting a match over the
filler neck to see how much gas is in your tank. Bad idea in my book!

I often hear people complain about the throttle cable not staying set when they pull it out.
My personal feeling is that the replacement return springs as opposed to the original
spring puts way to much tension on the linkage and that's what pulls the cable back in.
It’s been several years since I’ve had a W-1 on the bench but if I remember correctly the
accelerator pump spring holds the throttle open on them. Prior to 1950 the W-1 was used
by Chevy and the return spring tension required for the W-1 would have been greater than
for the post 1949 Rochester ‘B’. The vendors now sell a one-size-fits-all return spring and
I think it just puts to much tension on the linkage.
