Hi Wayne; I have only dealt with the spray bar to solve this issue. (Anyone interested as to why see post #352 - Please note engine was tuned for best idle and transition first).
I first started by only taking off as much as the bevel at the end of the spray bar. This only changed the # of turns out for the idle setting (best idle and transition ) but did not solve the problem. I decided to take more off. The second time was a charm. After tuning for best idle and transition, WOT finally belonged to the high speed needle valve. The low speed needle now clears the spray bar enough to slide a piece of heavy weight paper in between. The spray bar now protrudes only 1/8". (Sorry, I don't have a mic and there was no disassembly involved as I only backed the low speed needle out of the way - but here's a pic). Cheers.
