okhere it goes...

I trired the heat shield underneather the carb - does not work
I tried opening the throttle plates - does not work

I also noticed that if you watch it from shutdown it take approximatly 3 min. to strat to drip and it begins from the progression holdes.

What I did notice that made a huge difference was changing my bypass to 55.

I also played with my jetting to work with the 55 bypass (you can do that you know) and it made a 90 percent increase for the better.

I also used a F-11 emulsion tube and it runs beautiful from 2500 - up

My idle circuit is almost there it is definitly drivable and enjoyable but get a pop eveyone and awhile.

i also noticed that you should not even think about trying to tune for 14.7 it is too lean. At least in my situation.

if you can get your idle at 15.1 then off idle to 13.0 - 13.5 and level off at 13.8 cruise you will love these webers. I am able to get my cruise at 14.0 but it seems it is alittle to lean. When I see it at 13.5-13.8 it is loving it.

I know I will need to lower my bypass to about .45 or 50 and hopefully it will take care of the slight gap on acceleration.

Again, this is my situation my tuning and this is what works for me.

I will hopefully take the car out on a long drive Saturaday.

But back to the drawing board from the leak, but at least it is only a slight drop now.
