The metering rod slides into a brass plug at the bottom of the bowl. My question: Isn't there suppose to be a little ball bearing that goes in there, or am I bonkers? | | | | | Joined: Apr 2008 Posts: 502 Shop Shark | | Shop Shark Joined: Apr 2008 Posts: 502 | I do not remember any loose ball bearings in mine, Just the seat and the rod, it is only for metering, not for shutoff. The float controls the level. | | | | | Joined: Apr 2000 Posts: 179 Shop Shark | | Shop Shark Joined: Apr 2000 Posts: 179 | The 'plug' is the main jet. The rod comes up under low vacuum or open throttle to increase fuel under load. If there are any check balls they would be in the inlet and maybe the outlet of the accelerator pump passages.

While it is impossible to know what Dr. Goodpliers (the evil twin of Mr. Goodwrench) may have put in any carburetor; Carter built the type W-1 without the use of loose check balls. The inlet and outlet check valves for the accelerator pump are encapsulated balls or wafers. These valves screw into the pump column which connects the accelerator pump well with the pump jet.

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 | | |
