I have a Carter 730S carb that came on the engine when I bought the truck. It has a couple of holes in the base that are opposite to the slots in the carb insulator underneath. What do these holes do and by putting a gasket in between the carb and insulator that will open them up to "breathe"?
Thanks for all the help for this newbie.

Without pulling a carb to look at the passages, GUESSING one is for the vacuum power circuit, and the other is for the automatic choke.
When changing to any carburetor other than the original, one should ALWAYS use the mounting gasket supplied by the manufacturer of the carburetor in question.
I looked up the one for the 730s; it is Carter part number 1A-41.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | |
