I am in the process of tuning the round-top SUs on my 71. The first step is to set the idle screw and and jet level. The jet is supposed to be even with the "bridge," the flat part where the piston comes to rest when it is "at rest." This is possible on one of the carbs, but I cannot raise the second jet high enough. It is about a 16th-of-an-inch below being the bridge, I cannot get it to a flush position. Is it possible to loosen the jet jet locking nut and then make a "gross" adjustment so that I will be able to set the jet to flush using the jet adjusting nut? An other way of putting is, if I was rebuilding my carb how would I know where to place the jet before I held it in place with the Jet Locking Nut before I reassembled it and then made adjustments with the Jet Adjusting Nut? In case it helps, here is an image from the web showing the jet in the bridge. Can't tell from this angle if it is flush or not, but this is what I am trying to adjust.
