Got a question,

On my AFC housing on the opposite end of the diaphragm there’s slotted bracket that’s secured with a 10mm bolt that attaches to an eccentric pin that moves the do-hikie that rides next to the fuel plate up & down. What is this adjustment for?

 

I think that you are talking about the fuel shut-off valve....hope that helps.

 

No it's not the fuel shut off valve.

The arm that the AFC diaphragm accuates when under boost is the arm that this eccentric pin move up & down when you rotate it.

 

the "do-hikie" has a taper on it I think the adjustment you speek of is just a fine'r adjustment for the afc

just to tune smoke a slight ammount
