Gents,

Maybe my scheme of post 13 is a solution for bleed air, single needle valve carburators! (This is Classic Pattern Flying)
These carburators normally do not work with fuel (pump) pressure.
When I have time I will give it a try on my Orion with ENYA 60 4C engine!

Edit, Jeff I did not read your post when posting this one, you are also right, w'll see!
