Wilf,
maybe you have something there? Haven´t thought about that, but yes the floats could very well lockup sideways.
Those high flow needles, was it the off-road type or was it only the bigger type?
About the connecting channel, I think the purpose of it is to equalize fuel levels between chambers, one idea I have is to put open cell foam there to reduce speed of sloshing fuel but allow some fuel to pass by.
When I read a 10 years old magazine, an ad for "vaacum controlled fuel regulator" hit my eyes........... next words was "absolute MUST for Edelbrock carbs"!!!!!!!!
Anyone with experiences of this gizmo?
