how do you adjust it. Is it left down and right up. It whould not go either way so i just whant to make sure I go the right way befor I put some pressure on it and strip it out. can i use a stock pressure?

 

Screwing it in will inscrease the pressure and backing it out will decrease it. I have never adjusted a Holley unit but if it is anything like the adjustable GM units you have to break them loose before they turn freely. Just push in and go slow.

 

i stripped my vafpr torx head. i was very careful. i expected it to be difficult. not sure of best way BUT i think some heat will break it loose. i ended up shimming by the way.
