the VRO wires on this are not connected, all I've ever done was mix
50/1 myself. Today I took the pump apart again, the diaphragms were
not tightened properly, this time, by turning each side of the pump, I
tightened them right up. I think that may have been the problem!! I
hope so anyway.
I also replaced the lines from the crankcase and to the fuel filter
and pump.
I'll be testing it all tomorrow, if I stil have the problem, it has
to be the tank.
