Initial timing is 15 ...total is 34.If I idle at 1100 it's livable but still bad..Its auto trans..I'm sure its the air bleeds as it has the pro form center section..when it had the crane hys roller I couldnt get it to idle,so I set the whole carb to pro form and they set it up it idled fine.. ..NO Charge ..they were good to work with,,,but now after the regrind....bad bad
