Adjusting the Accelerator Pump (page 6)

To adjust, turn the nut till it works properly. Turning it clockwise (tightening) delays the time when it squirts. And turning it counter-clockwise makes it actuate sooner. The trick to maximizing the a/p is to have it actuate at the proper time, without reducing the size of the pump shot. This is accomplished by backing off the pump arm nut till the lever no longer contacts the plunger, then gradually bringing it in till it squirts as soon as the throttle is opened. It’s a trial and error adjustment, as what sometimes looks perfect when the car isn’t running may still slightly bog and need a little tweak to make it perfect. Consequently, if you go to far, you start reducing the size of the pump shot, which may actually help your gas mileage if the carb stays running ok, without a flat spot during acceleration that would be caused by the pump shot ending before the main/transition circuits can catch up and “come in”. Yes I like run on sentences. :)
