Who actually makes Hudson Machinery Inc?

What the Hudson Machinery filings say about the engines

Hudson Machinery's filings mix carburettors and fuel injection: 1 row carburetted, 1 injected. The first injected family appears in 2025; in 2025 the split was 1 carburetted to 1 injected. Check which you have before buying anything on the fuel side.

The engine codes on Hudson Machinery's test vehicles —2 distinct across the filings — are led by 1P56FMJ-3 and 182MN-P. The code is stamped on the crankcase and is a better search term than the badge.

None of the 2 filings is a 50-state certification: these were sold as 49-state machines, not certified for California.

Rated power across the range runs from 6.8 kW to 23 kW (about 9 to 31 hp).

The vehicle builder named on every row is Chongqing Nicot Motorsports 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.
