I have a 600cfm Holley on my car - 64.5 / 289 / Auto.I have the idle screw on the base removed and have tried adjusting the 2 screws on the metering block and still have a high idle on the car which I can`t change.Any Suggestions ??
**checked the butterflys - seem to be closed.Gas leak thru the carb.??Car runs fine just idles high.Thanks
