Re: Adjusting air/fuel screws on brand New England Stromberg 97
As B&S said, "PS: That chrome fuel pressure regulator with the dial . . . they're almost useless and cause more issues than they solve. If you really want a decent regulator, then you need to buy the low-pressure Holley one, include a gauge with it (so you can accurately set it) and mount it AFTER the mechanical fuel pump."
Holley 12-804
Low-Pressure Fuel Regulator (std. finish)
Low-Pressure Fuel Regulator (chrome finish)
