Important Fitment Information

Tecumseh engines within the same AH, HSK, TH, VSK, 1400 or 1500 engine family may use different primer bulbs and primer body configurations depending on the complete engine model, specification number and production configuration.

This primer bulb and body assembly is intended only for select applications originally using Tecumseh 570629A, 570629B, 570629, 570442A, 32182, 32182A, 32183, 32184, 32312, 23120003 or a compatible listed application with the same vented screw-on configuration.

Engine family, equipment model or physical primer bulb appearance alone does not confirm compatibility. Similar-looking primer assemblies may use different mounting, venting or connection configurations and may not be interchangeable.

Please verify your original primer assembly part number and complete Tecumseh engine model and specification number before ordering. Compare the screw-on mounting configuration and approximate dimensions with your original assembly where possible.
