What the USA Qunsheng Int'l Investments filings say about the engines

Every USA Qunsheng Int'l Investments filing on record is carburetted — 4 certificate rows, 2007 to 2008, and not one fuel-injected engine among them.

The engine codes on USA Qunsheng Int'l Investments' test vehicles —3 distinct across the filings — are led by 157QMJ, 152FM and 165ML. The code is stamped on the crankcase and is a better search term than the badge.
