The Moki company did not protect their name by copyright. The US importer obtained the copyright and will not allow engines to be sold in the US under the Moki name. The glow engines are sold in the US under the name of Mark.
Another manufacturer in Germany took the Moki name in Germany. This is the gas engines called RCS in this country.
I have an RCS44B2. The box it came in said "Made in Hungary"
You are welcome to explain it if you can.
