carter carburators
The Carter BBD is such a simple carb to rebuild ; I can rebuild 'em in my sleep !
One of the BBD's weak points is in its Air Horn assembly : they are usually warped slightly at the Accelerator Pump Plunger's inlet .
This will cause fuel "sweat" and permit too much air intake .
Whenever I rebuild one with the warpage , I'll fill the void with Ultra Black silicone , and smooth the silicone out before it sets-up ; trim the extra silicone with a new , sharp blade .
IF your Demon's got its original carb , it should have a tag on it with its build date , part number , and the last-three characters of the Chrysler P.N.
Also , the casting date is , well , cast-into the fuel bowl's left-side ; this is in Julian Calendar format ( i.e. , "3651" = 365th day of 1971 ).
Carefully inspect any "remanufactured" carb for blunted mixture screws and Accelerator Pump Plunger operation .
I've got hold of "reman" carbs where the mixture screws were blunted , and-or the pump plunger stuck-open (plunger in the down position ).
While you're at it , check the choke pull-off , choke heater spring , choke plate's seating , and how the Throttle Body's blades seat .
Sometimes , the choke plate and throttle blades can have burrs and blemishes on them ; dress 'em down with super-fine sandpaper or crocus cloth .
Good luck to you :drinkers:
