Another weber question
 

I did some searching, but it ended in more confusion. I've got my webers idling perfectly, the air correction screws and mixture screws are very responsive, idle CO is about 3.5% according to my Gunson.

Today I set the accelerator pumps using a $1.50 vile from the drugstore, both sides are at 6cc and the car revs fine. The thing I'm curious about is I have what I think is a lot of fuel blowing out of the tops of the stacks when I rev it. I get a pretty good sized amount of fuel at WOT. Is this a sign that my mains are too large?

Idles are 55
ventures are 4.5
air correction is 180
Mains are 140
Tubes are F1

Engine is freshly rebuilt, 964 cams, JE 9.8.2 compression pistons, MSD, magnacores, SSI's.

No you are seeing reversion...some of the intake charge is getting blown up because of cam overlap etc...

Tall air horns, and tall intermediates were the fixes...

If you ignore what you are seeing... how does the car run?

If it runs well.......

It runs very well, idles like a top, pulls like a train. In fact I can't imagine why I didn't get rid of the CIS earlier. If it's normal reversion, I'm fine with that.
