Hey guys, I have a '64 International B160 w/the 304ci V8. The OEM 2barrel Holley Carb vapor locks itself whenever the engine gets even moderately warm. From there I usually have to wait about an hour for the carb & outer engine to cool itself down before it'll start again. Needless to say this is incredibly frustrating, especially after stopping to get gas. Is there any way to remediate this? I was planning on replacing the carb with a much more modern one, but the mounting pattern on the old carb is very irregular, and finding an adapter is proving quite difficult. (OEM mounting bracket is 3.5" deep by 5" wide) Any suggestions would be very much appreciated. Thanks a ton for reading this and offering any help or tips you can.
