    Everything done but low rpm at WOT. Distributor spring?

    Guys I added a fuel pressure gauge just before carb and at first I got 5 psi which is in range. Now I get 3 when cold and 4 then5 when warm .

    Everything done but low rpm at WOT. Distributor spring?

    Thanks, I think I understand now some the difference between regular and marine carbs. We must be in the wild west up here in Vancouver BC because I would bet that there are many older boats up here running with regular carbs. There probably should be regulations, but I cannot find any...
