Debs, have you a laptop with a 'real' serial port?

Sadly not.......it`s just VGA and USB. :-[

'Idle' wondering: would a long period of battery disconnection, reset the trims?.......Don`t worry if not, I can easily wait `till the meet for your 'OOFicial' analysis! ;)

Have the throttle butterflies been checked and the idle valve been given a real good soak and clean yet?

 :y Yes, thoroughly soaked the idle valve..... and used a can of carb-cleaner (w/tooth-brush) to clean the butterflies/throttle-body; they were secure on the cross shaft, closed in synchrony and tightly held carb-cleaning fluid in the vestibule fluid when closed.

.....on a cold/cool engine; when the idle is 'flicking' (sorry, can`t think of another way of describing it; other than by what the tacho-needle is registering): RPM is first, well-above, then back down to the expected idle {for that engine temperature}, I`m surprised at how fast the engine revs are changing at that time, in fact, I`d struggle to replicate such rapidity of an RPM change using the pedal. :-\

'flicking'
Hunting?

 :-\ I`d have thought that hunting would be a more leisurely change of RPM around a fixed point....this is a very rapid variation. ;)

When you soaked the idle valve, did you also use a screwdriver (carefuly) to actuate the butterfly plenty of times?

A small artists paint brush is also very good for tickling the dirty bits with.  ;D
