Geoff,
There should be no stumble. If the stumble is when you open up the throttle
(step on the gas) you might consider going up a single size on pump jet - but
I think yours were already a healthy size.
Have a look at the deposits on the plugs (do a plug cut a la Vizard) and
consider going up a size at a time (ie try 150s first).
If you get it running really nice you could always consider going up to 36mm
main venturi (and 2 jet sizes) - the engine spec as I recall it will live
with this without too much loss of bottom - mid range torque.
Finally, glad to be of service and always interested in Weber (not just DCOE)
carb issues.

<< On Daniel's advice I tried 145 main jets on the Weber, up from 125. It
makes
quite a difference, almost no stumble and more power it seems. Also the
Micky
Mouse cap is installed over them and that seems ok too. (Previously, with
the
125 mains, it ran better without the cap). So, that would seem to indicate
that
it was running RICHER without the cap, which seems weird, but empirical
evidence
supports this theory!!! Should I try a couple of 155 mains next?? THANKS
DANIEL!!!!
