    Amazing what a little throttle will do

    I've had my SIII for a dozen years, hauling it around a number of locations. Most of them (except Calgary), I was pretty much the only Series truck in the vicinity, so all the maintenance and upkeep I did myself. It takes work, but I'd managed to keep things running, mostly. This being the only Series I'd ever driven, I just got used to how it ran. Now in Anchorage, and I've found a real Series mechanic, and it took him one short (aborted) drive to realize something was missing. Apparently, in upgrading my carburetor(s) over the years (especially from a Weber to a Zenith), I did not understand the linkages well enough to set them up differently. I've been driving all this time with only about 2/3's of the throttle available to me. Ed (Steadfast Offroad) quickly updated the linkage, and now I can actually accelerate just a bit - and even go up a slight highway grade in overdrive. I feel like I've been given a turbocharger. Yes, it's still slow, but I've been slower all these years.

    Just one observation that only having one truck to compare to is not much to compare with.

      No better way to make a 2.25 seem zippy than to de-tune it by 30%, drive it for a couple of years, then, give it back all 70 of it's blistering horsepower, then go for a drive!

          I know the feeling. As I've related here before, I drove an SIII in college that must have been detuned 20%. I had no idea, until, on my current daily driver SIII, I rebuilt the top end, switched to a Rochester, and tuned it to within in an inch of it's life, that I could idle smoothly and almost silently down below 800, and cruise pretty comfortably (if a bit loudly) at 60 on the highway all day. (Just proved it with a 500-mile round trip to Oktoberfest in New Glarus, WI, and Milwaukee).
