Likely
  • 594636 — Toro 20334 (serial 400000000 and higher) — engine confirmed as Briggs & Stratton 675EXi on Toro's own product specification page

    Manufacturer chain: Toro's own product page states this model ships with the 675EXi engine (Engine Brand: Briggs and Stratton. Engine Series/Name: "Briggs & Stratton EXi 163cc w/ReadyStart and Just Check & Add".). That engine's carburetor rebuild kit was independently verified against a Briggs & Stratton parts diagram in an earlier batch — see that engine's own catalog row for the diagram citation. Independently corroborated on PartsTree's own parts page for SN 400000000-401999999, which names the engine as "Briggs & Stratton model 104M050040F1" — 104M0x is the 675EXi model family already in this catalog. For engines with a code date after 15030800.
