[Chrysler300] AFB 2903 electric choke conversion

["John J. Hertog" <crossram@xxxxxxxxxxxxx>]

Hi to all, 
 
Motivated by the sight of yet another set of original 50,000 mile ram
manifolds burned out in the choke pocket area, I asked Jimmy and Bobby at
Allstate Carburetor (www.allcarbs.com)  whether it would be possible to
modifiy the 2903 carbs, and add electric choke units to them without any
permanent alteration / damage to the carbs.  The answer was:  "I don't see
why not".  They are now in the process of converting a set I gave them. 
 
The idea, of course, is to block off the heat riser system, by inserting
solid shim plates between the exhaust elbows & heat tubes,  and the bottom
of the manifolds; one would also want to jam the heat riser valve in the
open position (assuming it still functions) on each side, and disconnect the
choke pulloffs. 
 
The benefit would be fully automatic choke operation without any heat
supplied to the bottom of the carbs.  No exhaust damage to the rams, no
baked off paint either. 
 
I will be glad to report on the progress of this carb conversion and take
pictures when I get the carbs back. I can ask Jimmy and Bobby to put
together a "conversion kit" and make it available for sale, if someone else
wishes to do the same to their 2903's ( I understand that they will have to
fabricate one linkage piece) ; or you could just send 'em your carbs for
conversion and/or R&R. All removed parts would of course be returned. 
 
For whatever it's worth, Allstate Carburetor has rebuilt umpteen sets of
2903 AFB's for various Club members in the past few years. 
 
Comments, anyone?
