Okay....
The temp gauge - have previously had an AutoMeter electric gauge in there (with its own sender), and it read... surprise, surprise, hot. About 200+.

Not cool, as this makes it a difficult problem, not just a gauge fix, and the top hose feels damn hot anyways. When the gauge says Normal, i can still (just) hold onto the top hose. Trust me, the gauges all work fine.
Dyno specs - I have the dyno chart here infront of me, and it has the air/fuel ratio on the scale. It was WAY high at 15.(Lean) before it was tuned, and it now sits at about 9, just about perfect. I trust this dyno, as this man has played with webers and Minis for years. I know of many hottie old cars, all weber-fed, that use him and his dyno regularly. Most of the SA field of historic Nb and Nc racers for a start.
Exhaust - Yeah, i've had enough for now, i need to learn how to MIG weld! Screw these guys that charge like a bull at a gate, but achieve nothing. It already has a flexi joint, but all the flexing is happening in the pipes. It really needs that gearbox mount. It would help if the threads were still in the casing, as the first Zaust shop decided a coarse metric bolt would look much better in that hole. (Thanks again, Marky

)
Throttle - I've had the pedal out, the cable out at least three times, and all the linkages to the weber in and out just as many. I have now had 4 different links to the weber, but no joy. I think i'll play with this one some more and see how i go.
But, for now, i'll leave it all a while. I have blown about $6000 in almost four months on this F**kin car, two motor rebuilds, two radiators, three sets of extractors, two full exhausts and i've had
enough. I have a very large show the car has just gotta attend at the end of the month, so i might try and have it all sweet by then. But my bank account needs some rest!
