Apparently, there is more than one adjustment on this version of Z-S's. I thought the only one was the jet "screw" under (above) the float chamber plug. I'll have to review. My vintage Haynes manual doesn't cover the version of Z-S that is on the car. My Spitfire carb was not adjustable at all, jet or needle, other than swapping needles.

On the idle speed increase when the engine gets hot...Unfortunately, flipping the bi-metal springs around didn't help. It's bizarre. When just sitting in garage idling, temp gauge gets to about 75% and idle increases dramatically. No working tach, but it probably goes from 1000 to 2000. Always about the same temp range on the gauge.

Member of local Triumph group gave me the "choke" mechanism to put back on the rear carb. It won't actually do anything, but it is more attractive than the paper tape that currently covers the holes where something used to be.

For running/driving purposes, the car is back to "normal". Starts with little choke, idles fine (a little rough, but it is 37 years old), has power when stepping on gas. Will squeal the tires in 2nd and get to 60 MPH in 3rd. MUCH better than a couple of weeks ago.
