Sorry for the repeat question guys, but I,m still lookin for info about the idle when using a big bore throttle body.
I found a TMW thr. bdy. but there isnt an idle adjust screw on it. I,m installing on my 76.The stock thr. bdy. has an air journal which bypasses the valve to supply the engine with air at idle.The idle adjust screw works by restricting air through this journal.
As I wrote, this paasage and screw do not exsist on the b.b., but there is an extra port on the intake side of the body. I'm wondering if i can connect a line from there to somewhere on the AFM side of the thrttle body with an adjustable valve to act as idle.
Any info will help...
