That sounds like a good possibility. These carbs can't be changed to manual
choke due to the different castings used. I guess from their general
dimensions that they would fit onto an MGB or similar without any trouble,
but the 'chokey-bit' gets in the way for anything with lesser spacing
between the inlet ports. Using a normanl 'rear' carb will work, but only
one of the carbs will have a choke, however that was how the system was
configured in the first place.
I'll try 12V over the terminals and see if anything smokes! Thanks for the
help.
