I have just got 3089R running after many years and there is a problem with fuel dripping out of the inlet trumpets of both 40DCOE Webers at high revs.
I have checked float levels, I have thoroughly cleaned out the little barrel filter as the fuel enters just after the banjo, I have cleaned out the needle valves which the floats push on, the floats are not damaged, but when the pump is pumping at high revs (over say 3000), both carbs are dripping fuel.
Why is this happening to both Webers? Is the fuel pressure too high from a standard AC Delco mechanical pump?
Luckily I noticed this before venturing out on the road.
Googling 40DCOEs flooding, it seems this is quite common. 3.5psi seems to be the correct fuel pressure. I wonder what pressure my AC Delco is pushing out.
