[6pack] Anti-run on valve after Strombergs are replaced with Webers

[Sally or Dick Taylor]

I'm not familiar enough with the Weber to know if there is a way to connect the AR valve to their float bowls. But if run-on is a major problem, take a look at Roger Williams book on "How to Improve....." and you'll see a note on connecting an aftermarket valve to the intake manifold. Looks like they can be sourced from England. From what I can gather, turning off the ign. opens a solenoid, which vents to atmosphere. No suction, no run-on.

Stan,

I also have triple DCOE's and I am looking forward to the responses. I
also have problems with running-on and would like to find a solution.

The hose of my Anti-Run-on valve is not connected, and the electrical
not connected either at this time.

You mention:
" ...  so the AR valve just has its original  connections to the inlet
manifold via the banjo that also connects the servo and to the
canister"

Where is it connected to the canister, which outlet connection?

I had considered connecting the AR valve to the banjo on the manifold
but your comments indicate that it does not stop running-on. I suppose
that all it does is lean the fuel mixture a bit but not enough to stop
the running-on. I was hesitant to connect the AR Valve to the banjo in
case the valve leaked and caused a lean mixture to the engine.
