[DML] Re: Initial Setting Of CO Screw

["content22207" <brobertson@xxxxxxxxxxxx>]

Unplug the coil, jump the RPM relay (remember that the pump spins
continuously like that, whether the car is energized or not -- don't
leave it jumped), pull an injector and place it in a bottle, and set
your CO screw lean. Then turn the engine with the starter motor
(lowering the air sensor plate naturally) and enrich the CO screw
until the pulled injector starts to spray. This should be close enough
to start the engine and make your final adjustments.
