71 Mustang Idling To Hogh
 

I HAVE A 71 STANG AN IT'S IDLING TO HIGH I JUST PUT IN A NEW CAM AND A 1850 HOLLY CARB. I SET THE TIMING AND THE IDLER ON THE CARB BUT NOTHING HELPS. I'M NEW TO CAR AND THIS WAS MY FIRST ATEMP AT BUILDING A CAR AND I DIDN'T WANT TO CALL IN A MECHANIC. I'M OPEN TO ALL SUGESTION PLEASE HELP

You did adjust your timing with the vacuum advance disconnected right?

Does it still idle too fast after it's warmed up. Remember, u have a fast idle when it's cold. If so, check to see if it's sticking.

can someone please explain why you need to disconnect the vacuum advance on the distributor before you set your timing?

All i ever do is adjust the idler screw on the carb it always works for me.

Betcha it's your choke.... is the butterfly wide open?

Well I guess nobody knows:rolleyes:

Sorry, I do.

It's because when u are adjusting your timing, u don't want anything else but u adjusting it. Sometimes there is still a little vacuum left in the hose, or maybe your car is idleing too fast, and creating a vacuum. U want to rule out everything else to get the timming more percise.

I could have answered him. It was just a bit hard for me to believe that someone with all those mods could ask that question.
