DISTRIBUTOR 23D ELECTRONIC NEG EARTH

NEGATIVE EARTH ONLY. Cooper"S" 23D distributor, no vac unit-This is NOT THE ORIGINAL LUCAS ITEM but a new contact less electric copy of 40819 to cope better with modern day fuels. Fitted with the better Red rotor arm upgrade.Cheaper than many electronic ignition kits. For best performance and tune we advise our electronic evolution version C-27H7698 in a 45D body

The original type base plate with pin 7H6949 is also available but expensive. Fitted all Cooper S models but some MK3 "S" were fitted with 41033-23D type--(Note:25d type distributors have a Vac unit.)-This distributor has more advance curve similar to the 41033 (Mk3 "S") which was better for acceleration and economy.See graph on web site from Peter Baldwins rolling road. The 41033 or 41732 Cooper S mk3 distributor was replaced with a 45D type BAU1850 by Rover less a vac unit which fitted Canadian 998cc minis and Marina 1.3 HC engines, but it was never a true replacement part for the Cooper S Mk3. This is why 12G2140 MK1/2 "s"distributors found their way on these cars.

See C-27H7711 23/25d distributor less vac unit as this looks the same but has electronic inners that will not let you down and has 16 different settings which have given extra power to every car they have been fitted to.

Also fitted to in line engine 1275 Sprite and Midget the 40819 is 7 degrees btdc static and 22 degrees @1200rpm dynamic timing--centrifugal advance in degrees @rpm was 0-3 @600/--6-12@1000/-- 11-15 @2,000/--22-26 @5,200/

28-32 @7,000
