Well, really I'm an electronics and comms engineer, so the hot-start problem
was easy enough (sensibly sized battery cables made up with a hydraulic
crimper from t'office plus a fork-lift battery connector under the dummy
tank on 25 sq mm cables for jump-starting, charging etc. ), and the idle's
set right now :o)
PS it's not a "tweak the carburettor", that's all fine, it's a "tweak the
linkage, there's an adjustable stop"

Yeah, well, most riders don't want to re-engineer their gawddamned starter
cables to get their engine to start when it's hot and the mixture is pre-
igniting and making the starter's task more difficult. Most owners just want
the gawddamned bike to start under all conditions.

Oh, so the linkage is not part of the carburetor bank now. I'll have to
remember to be pedantic the next time I need to tweak my carbs.

I guess you live in Theory County - everything works perfectly in Theory ;o)

Nope, the carbs' job is mixing air and fuel in a suitable stochiometric
ratio, the linkage's job is to coordinate airflow through the carbs -
tweaking the carbs will vary the mixture (hopefully in a predictable
fashion) with a knock-on effect on engine revs, tweaking the linkage
balances and synchronises the carbs and sets the idle speed, simple as that.
