Who actually makes Smartwell?

What the Smartwell filings say about the engines

Every Smartwell filing on record is carburetted — 2 certificate rows, 2007, and not one fuel-injected engine among them.

All 2 filings are 50-state certifications, so every one of these machines was certified for sale in California.

Rated power on the record is 4.3 kW (about 6 hp).

The vehicle builder named on every row is ZHEJIANG SHENMAO APPLIANCE CO., LTD.

Each figure is read straight off the EPA certificate rows; the per-family pages below carry the full breakdown for every engine family.
