Having the blower surge curse. At idle with surge I can see butterflys mving in and out as the idle goes up and down. I can put my finger up against the butterflys and slow the surge a bit. I can still feel the butterflys moving with my fingers on them. So my thought and qustion is this. Has anyone tried shutting the butterflys compleatly and using some sort of needle valve in the hat to regulate the idle air and if so where did you get the needle valve?
