Jeff and Dick,
How can your cars run optimally at all temperatures with ability change mixture according to temperature eliminated (by eliminating the thermostat to the MFI rack)? Its like saying putting a brick on the gas pedal works as well as cruise control. The screw jerry rig will set mixture at a fixed level. It will not allow the car to run richer when cold and leaner when hot automatically which is ideal for a street car and why the thermostat is there. So you either have to set your screw in the middle so it runs when cold and hot (neither optimally). Or set it lean or rich. These cars will run just fine rich but are leaving HP on the table. leaner is faster (but dont run well when lean and cold). Another example, Do you set your timing with just a screw and eliminate the centrifugal (automatic) advance?
