Dreads, some seriously bad misinformation has been dished out by the unknowing, and the following may help you to work more effectively. In these carburetors, everything impacts everything else, and there are no hard boundaries for component effects: pilot jet selection affects mixture screw adjustment, and jet needle position often forces a change in pilot jet selection. Yep, needle position has a strong effect on the idle mixture, even though needle jet and jet needle are main circuit components. Even at idle, with the throttle plate nearly closed and the slide all the way down, the needle jet and needle are contributing fuel to the mix through the slide cutaway.
Good stuff as always, 2M! But I've found it very tricky at best to modify a float bowl plug to hold a piece of tubing. I think it was gggGary who recommended using a 6mm. metric grease zerk with the spring and ball removed.
