webers (the gasoline kind)

[Tom Jennings <tomj@xxxxxxx>]

So I have this 32/36 DGEV (two-barrel progressive) Weber carb on
my 258.  I've got the main barrel barn-door dialed in. It was off
a Jeep so it didn't have far to go.

I bought the popular book on Webers (it's out in the car, too lazy
to get) which frustratingly leaves me in the dark on the two items
I need to know:

* ported vacuum?

* adjusting 2nd-venturi issues?

It appears that Webers simply don't provide ported vacuum (eg.
vacuum signal for the distributor picked off right above the
closed throttle plate). I've got the timing set statically to
5btdc, but then I stick the hose on and get 20 whatever btdc
degrees.  Runs OK but I don't like it.

I have a huge bog when the 2nd venturi opens, plain and simple.
Load or no load. The accellerator pump hasn't run out of stroke or
anything when it starts to open, so I don't think that's it.  If I
ease through the bog region it flows OK and the motor pulls like
hell, so the jetting isn't too crazy. I assume all I can do is
bend the linkage to determine pull-in.


Does/has anyone run a Weber on a Jeep or AMC and know anything
about these things? I'm hoping I can get through fall/winter with
this thing until I get a TBI system together.


Overall it's running really well. Idle, in gear, then quarter or
half throttle breaks the tires loose with no effort. While the
tires aren't exactly slicks, the axle is 2.73.

I can't make it ping at all so I have room for more advance!
Sweet!
