Re: [DML] Carburete a DeLorean at DCS'12?

["content22207" <brobertson@xxxxxxxxxxxx>]

Just FYI:

No screws -- Autolite/Motorcraft 2100 carburetors use jets alone (in conjunction with physical characteristics of the carb itself --  venturi size) to determine fuel/air mixture. The only adjustment screws are needle tipped and determine how much of that mixture bypasses the throttle plates while closed at idle (Motorcraft 2100 only has one pair of jets, and it uses the same metering passages for idle and throttle). It's a nifty design that uses nothing more than air pressure alone (no moving parts other than the throttle plates themselves) to switch between idle and throttle circuits.
