No worries. Kaddies with ported advance, I've run with rebuilt standard SVDA (VW German or Aussie) distributors or a 123TUNE+(my electronic option) and have always pulled well. I find that in most cases you have to go down a jet size in both main and idle jets(better fuel economy!) as the motor then starts fouling plugs due to running cooler and not requiring the above(009's , aftermarket stuff curved badly and franken-ignitions) to fire plugs on poor advance curves and folks throwing fuel at the motor to get over the dead/flat spots. Both Kaddies need mods(x1 to plug the vac port above/below the throttle plate to stop bypass air and x1 to mod for the vac port-also plugs the bypass while doing it). It's relatively simple to do, only I've found most carbs handed to me have been knackered and requiring a rebuild on top. You don't need the added hassle of an extra 4x plugs, in fact a waste of $$ imho. Imho, where you have that vac line is pointless for sensing engine load. It cannot ever be sensed there.
