I'm trying to help a friend with his recently completed 4BT project, the subject of which has undergone some tuning during its time of service. What we wish to do is return the pump settings to OEM, or as close as possible, to establish a baseline for for future mods/adjustments. Specifically, I would like to know the following:

Position of the full power screw. A measurement from the head of the screw to the top of the locknut would suffice.

Clocking of the tapered fuel pin.

Position of the starwheel under the AFC spring. Number of turns up from the bottom, a measurement from the top of the tapered pin guide down to the starwheel, etc.

Any info would be greatly appreciated.
