Correct Gilles; no oil damper pots on the Bing carbi unit, just SU and Stromberg
constant depression units, same tuning/diagnostic techniques are useful for
all three types; the Bing differs to the other two in that their is no external
facility to adjust the main jet mixture (only internal needle height by circlip,
or adjust piston raising speed on wot acceleration by damper pot oil viscosity
as the Bing uses an air damper setup (adjusting piston rise speed is done
via the piston spring tension; for aviation this is not applicable as throttle
augmentation is minimal during operation)
