Carburetor PistonThe AC16151-D0100 is a piston component used within the forklift carburetor enrichment or choke circuit. Its precise fit and travel determine the additional fuel delivered during cold start and warm-up, helping the engine catch and idle cleanly until it reaches operating temperature. A free-sliding, properly sealed piston is necessary for reliable cold starts and stable enrichment behavior in the carburetor. Supplied as an aftermarket replacement part that meets or exceeds the form, fit, and function of the original component. Confirm the part number matches the carburetor or assembly on your forklift before installing, and replace any related gaskets, seals, or hardware disturbed during service to maintain a leak-free seal.Aftermarket replacement part, cross-references original part number AC16151-D0100.Need help confirming fit?
