Interesting Weber jetting

My old weber setup was now no good any more, and my self made emulsion tubes ran horrible.
So I got back to tuning.
First thing I noticed, now that the engine runns hotter because it is so new, is that the pump jet dumps gasoline into the the carb when the hot engine is turned off. All my efforts to keep the carbs cool have not brought any improvement.
I noticed that the gasoline in the accel.pump circuit starts to boil and spills out of the only orifice it has , which is the pump jet. This happens only with the 0 pump spill. I used th 0.50 pump spill, which got away with that, because the gasoline can flow back into the bowl when expanding.
Since the 0.50 pump spill produces a slight flat spot, I have ordered 0.35 pump spill valves which I hope will work better and get away with the slight hesitation on acceleration and prevent fuel spilling into the carbs when engine is off.
I used the newly ordered F14 tubes, which seem to work fine, but the top end is lean now with 120 air correction jet. I tried 100 air correctors and that is now much better, but I have ordered 0.85 air correction jets because that is what I think will work best.Main jet is 140 now, and idle jet is 70 with a 100 holder.
Next weekend I will get back to tuning with the new parts ordered. Will se how it works out.

Where do you have get your 0.85 air correctors difficult to find in these size (0.80/095)
Thanks
