Fuel leak question

[priobe]

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.

Priobe : thanks for the results.
What venturi size are you running?

[priobe]

I am running a 40 mm venturi.

However, as many have mention (Inglese and others) by moving up to a 42 mm you will only have to adjust your mains. I think differently I think more than likely you will have to rejet your mains stack as well as idle slightly, as Ejaro is experiencing.

My ultimate goal is to go to 42's them remove them all together ( no choke) just to to see what will happen.

Another item I dont understand is why would one increase the 48 to 51 to only put a choke back in it. You will then reduce the 51 back to what ever the choke is.

An I know the throttle body is not beveld like the choke but the 37 mm choke that many were running were probably more resticted than what ever turbulance the no choke would deliver.

Just my .02

Priobe;
The reason you would open to 51 is so you can put in a slightly large venturi and still have a tapering bell shape bellow the choke diameter.
This taper allows the signal strength to increase on the augsillery venturi as the air speed increases
With a large venturi and no taper at the bottom half of that venturi the car would have a tendancy to fall flat on its face when the mains are being asked to come on and get stronger.
A smaller air corrector would help also when venturi is larger with less taper.
