I'm running a Carter electric pump for carbed engines like mine that is supposed to put out around 6 psi. I have a regulator, though I really shouldn't need it. My problem is that the pressure sits at around 7.00-7.50 which I think is too high for the needle and seat. No matter what I do to the regulator adjustment the press. never gets below about 6.50, and it shouldn't be that high in the first place! Any ideas?
