Hello! I have a 427 in my Sanger Hydro with a tunnel ram and two new 600 Holleys. Runs great but have a problem with the motor idling. Haven't played with the carburetors at all except to make sure float bowls are full. Checked for vacuum leaks and none. I have to play with accelerator peddle in order to keep running. When I let off of it and idle comes down it dyes. I'm running at 5psi on my fuel pressure. Was told to run a piano wire in the holes on carbs to allow more fuel and less air. Not sure if this is the way to go? Even had problems with a single carb on the motor. You have any ideas? Steve
Wire in the IFR's will lean it out at idle not make it richer. Might help, might just have you chasing your tail. But you say there were problems with idle before the dual carb setup? I would take both carbs off. Make sure primary blades are correctly adjusted (squared with idle transfer slot). Then open back barrels a little more than equal to primaries. Put 'em back on and try it.
