Any tips?
TR3 that runs very smoothly and pulls very well up hills with just a light
touch of the gas pedal, even with od in. But on level ground when not
loaded starts to get a bit jerky when the rpm falls to around 1600 or
lower, almost as though a plug was bad. Sudden treading on the gas pedal in
this situation can produce a coughing of the motor, which then picks up. On
stopping engine idles well initially but revs fall over about 20 secs and
then the engine dies. Lots of fun at lights.
This got me looking and reading around the subject of su carbs and
adjustment of them. Pages like:

http://www.teglerizer.com/sucarbs/garrettech.html
http://www.mame.mu.oz.au/salman/S.U.html
all make for interesting reading. In particular this article -

- talks about testing out your needles at different speeds with an exhaust
analyser.
Anyone tried one of these, or know of any product names for the job?
