Hesitating Holley

I know that there is somtimes some confusion about the pump clearance setting. You need to set the accelerator pump lever to .015 clearance at wide open throttle. To do that you need to use something to push the accelerator pump lever down all the way while also opening the throttle all of the way. Then you use a feeler gauge to check the clearance with your third hand. The idea is that you don't want the the accelerator pump to bottom out at full throttle, which will harm it. Some people read the spec and set some clearance between the cam and lever at idle. You don't want to do that because the accelerator pump will not work soon enough, there should be no clearance at idle. This has probably already been set up for you, but I thought that I'd mention it.
