I have a zenith 63awll updraft carburetor on a tractor that came off a 248 chevy. It's currently on a 283 waukesha. It works good and lugs fine, but can't get enough fuel out of it under load. I drilled out the main jet some, but now that affected my idle circuit. It over fueling at idle no matter what I do except to turn in the load screw and then you don't have enough fuel under load. What do I need to do to get some more fuel out of load circuit? Any help would be appreciated.
