What size threads are the fuel screw? How much will the egts change with lets just say 1 or 2 turns. Will it be drastically or not to noticable. im betting a little on the higher side. right now im running 1075 wide open with the mods i have in my sig. thanks guys

 

Do a search on fuel screw, I believe Bearkiller at one time posted the thread pitch and dia., but I may be mistaken. I just tried to chase mine and the average metric tap/die set didn't have it. I believe its M8x1.00??? Wanna will know for sure off his head.

 

yeah i have been searching im sure wanna will chime in for sure knows it all

 

m8 x 1.00 seems to be the ticket thanks guys.
