[F500] fuel pump dilemma

[Dan Morency]

We have been working through our "bogs out of a fast corner problem"

we've cleaned and lubricated the driven clutch, it operates better now. I'm
not sure what type it is... it has an internal spring that sort of preloads
the clutch sheaves with six positions, 3 on each side of the ramp with the
"button" on it. It has 3 of these ramps 120 degrees apart. It was on one of
the middle 2 holes, what does changing this spring seat position do re
clutch tuning...  Externally the driven clutch has a rounded bell appearance
about 3 1/2 inches in diameter in the center.


We cleaned out the fuel system from carb to fuel pump. Tank and pickup
tonight... no obvious problems

We measured flow rate from the electric pump. 1 gallon takes 2 minutes and
20 seconds. Is this too low? I haven't put a pressure gage on the fuel line
output.

NOTE: It only bogs when the tank is full, if at 1/2 full it runs fine. I see
no reason why fuel level should matter.  Ideas????  Help
