this is true, dennys just taking for granted everybody would know what hes talking about. when GM first put the elec. sol. on their cars it was because, everybody wanted ac, but you had to idle the crab. up so hi. with the ac on, the smog motors didn't won't to cut off, because you were to far into the carb. transfer circuit, so this was the fix. when you tuned a motor with the elec. sol. on it you disconnected the sol. and adj. the carb. with the idle screw and air screws down to 400 rpm's. then you pluged the sol. up, and adj. the sol. to 700 rpm's in gear and ac on. the 400 rpm's came by adj. the air screws with the betterflys closed. with the ac off, car in park, if everything is right the motor should idle. at 400 rpm.
