thanks tom, i thought i read somewhere its good to plug pvc. ill try it left alone. the cam is 248 at 050. overlap 28.

race demon 750. #75 front #76 rear + power valves front and rear. the fastest idle is with 4 corner screws almost seated!!! i ordered smaller idle feed restrictors in order to lean out idle. but that is a couple week order. the local speed shop claims that they are just holly emulsion jets and will fit as idle feed restrictors also in my demon.. hmmmm. so i should set idle mixture where idle is highest??
