Oil Drip from Air-box Drain - Normal?

Tell us more about that “long pull cable.” I’ve never heard of it. What does it do?
I think most of us get around 5gph without a special cable.

The Strom set-up in our birds do not allow for mixture cut-off . Only mag shut down. I had a "long pull" mixture cable installed on my C-85 and now can lean down to 5 gal/hr (or less) Before the cable it burned 6 to 7 gal/hr

I just shut off the header tank valve on my ramp and rev it up until it dies of starvation. I do this every time before I hangar it.

Oh, yeah. Right. I turn off the fuel valve a couple minutes before getting to the hangar.

Okay great. Now how do you lean out a Stromberg enough to kill the engine? Pulling the mixture doesn't seem to kill it.

I had the same problem. The A&P in the hangar next door told me that as the engine quits, there is considerable vacuum in the intake manifold which sucks oil past the valve guides. The solution was to shut off the fuel, and as the engine dies, open the throttle wide open so lots of air gets into the manifold. The drips have stopped.
