system would work for leaning manually. Lectron was the first to my
knowledge to SUCCESSFULLY produce a complete single needle system

carb

that actually worked.

Isn't a Zenith/Stromberg CD or SU's single needle? My Lotus Europa runs fine on 175CD's since 1974 with a bit of needle
and damper oil tweaking;-)

NO. The Constant velocity carb is a different animal. They use the
piston
and vacuum chamber to handle all kinds of midrange duties, but the top
end is controlled by the main jet. Many types use pilot and main jets.
The
Lectron is a single needle controlling from idle to WOT. The Lectron
isn't
a CV type, it is a slide throttle carb.

Bill, thanks for the info;-)
Can someone if they have these take a few pic of the metering rod setup in
this carb.

I was wondering if they were density and altitude compensating. Here is a
good write-up. But I wonder how wide a range the carb has.
