Under normal circumstances, if you place the gears in the reservoir housing such that the alignment dots on the black plastic gears sit at about 12 o'clock, and you then install the Rack Gear with the operating handle in the home position, you should be dead one.
Once installed BE SURE TO CHECK by operating/cycling the machine - BE CAREFUL, if you do this with the Shot/Powder tubes or EZ-Fill removed. The Rack Gear can pop-up and there have been occasions where one has broken off a piece of the aluminum reservoir doing this. I keep a finger on the Rack Gear, if exposed, while I operate the operating handle.
DO NOT advance the gear's timing marks. If you feel that you must, then this is an indicator that the Index Pad is probably adjusted too high.
HOWEVER, don't simply go and readjust the Index Pad... go to my website and download the Index Pad Adjustment Instructions and read them FIRST. If is a bit more involved that a simple up/down pad adjustment.
