  • Fuel System: AFB carb for Supercharged R2's

    I have just installed my rebuilt Supercharger on my 1963 Hawk R2 and although it runs great, the accelerator pump spews fuel into the atmosphere the more I rev the engine up. My manual suggests that the AFB carbs on the Supercharge R2's were sealed differently. Anyone have any idea's/suggestions??
    Thanks,
    Ron

          Are you using the original Carter AFB or an Edelbrock clone? The seal for the original carter AFB is available from SI http://www.parts123.com/parts123/yb....Z5Z5Z50001003a
          . If using the E-carb then the marine Accel pump will fix that issue.

              You have to pry the old one out with the carb top off, then tap into place and maybe stake it, to make sure it stays in place. Remove the metering rods and springs before taking the top off, make sure to use a new top gasket and seal the center rear screw-follow the manual. Put the rods and springs back in after the carb is assembled--no risk of bending them that way.

                OK, now I'll ask a dumb question. Does the accelerator pump seal go in o'ring down or o'ring up?

                  pointing down towards the pump well, put a little lube on stem (petroleum jelly works fine) and don't snag it with the accelerator pump link hole or it will leak. Don't forget to seal the threads on the top screws as per the manual.
