Thanks in advance for any help on this. I rebuilt a Holley 4160 and it runs great (my first carb rebuild). It is a manual choke, and before the rebuild the choke plate was wired open. To keep an old school feel, I installed a choke cable. When I pull the choke open, the choke plate doesn't close. If I manually hold the choke plate closed and turn the crank, it fires right up. I looked at various exploded diagrams of the 4160 and can't figure what holds the choke plate closed. Is there a spring or cam that controls this? Any pictures of your Holley or suggestions would be much appreciated.
I ran a 4160 Holley that had the same issue. Found the cause to be a simple one... either too tight a bend under the dash going to the pull knob, or the screws holding the cable to the carb weren't adjusted properly. Any way here is a picture:
I either put a wire in to hold it in the open position or remove it all together. A couple of pumps, it fires right up and never worry about flooding. Happy, happy, happy!
When you set it, you must have the knob all the way in. That is the wide open setting. Then set the choke place in that position, and secure it, and the cable end, to the appropriate brackets. To close it you then simply pull the knob out until it won't go any more. It sometimes helps to floor the gas pedal briefly when closing it up, for a cold start.
Never push the knob all the way in to set it. Leave 1/16th to 1/8th inch out then set the choke in the full open position. This leaves some wiggle room so that you'll know it's fully open and not the slightest closed.
