Original MTD KM490432065 — primer pump / primer bulb assembly for small carbureted engines. This compact black rubber primer with a molded plastic base is the push-style bulb that fits into the carburetor priming port to supply fuel for easier starting and to stop leaks from a cracked or hardened bulb. It is the direct equivalent of Kawasaki part 49043‑2065 (490432065).

Fits a range of small Kawasaki two‑stroke and similar garden-engine applications — commonly listed for TD18, TD24, TG33, TF022D, TG020D, TG024D, TG028D and TG033D engine models — and is used on various backpack sprayers, brushcutters and other handheld machines that share that carburetor priming arrangement.

What you get: one original MTD primer bulb / pump (KM490432065) — ready to swap in, no modifications required; replace the old bulb to restore reliable priming and smoother cold starts.
