If you wish to remove the pressed tube from the base (throttle body), PROVIDING THE THROTTLE BODY IS CAST IRON:
(1) remove the throttle body from the rest of the carburetor
(2) heat the throttle body in an old oven to the maximum temp of the oven
(3) remove the throttle body from the oven, and using an acetelyne torch, heat the are around the tube until cherry red
(4) SET THE THROTTLE BODY ASIDE AND GO DO SOMETHING ELSE FOR 30 MINUTES!
(5) once the throttle body has completely cooled (NO QUENCHING ALLOWED), find a screw or nail that will just fit inside the tube.
(6) with the object inserted into the tube, clamp the tube and object with a pair of vise-grips.
(7) gently turn the vise-grips, the tube will come right out
(8) DON'T USE JB-WELD! if you are a fisherman, find a split shot lead sinker somewhat larger than the hole, and with a drift punch and hammer, insert the lead into the hole. If you are not a fisherman, surely you have a friend that is; or a $2. pack of sinkers from a discount store.
DO NOT USE THIS TECHNIQUE ON ALUMINUM OR ZINC ALLOY BODIES!!!
