Essential part for good running!

International Harvester Case IH Farmall Cub carburetor idle vent tube for the original Cub carburetor. This is the tiny brass tube that threads into the top casting on the original Cub carburetor. These are often broken by inexperienced owners who separate the two halves of the Cub carb and do not realize the tube is there, resulting in breakage. The Cub engine will not run smoothly unless the carb has this part in good condition.

Note: The pictured part is the OEM factory part; but, we are now supplying an aftermarket part because it is half the price of the original and will work just as well.
