Tom, there was a nozzle on the intake that fed oil to the engine by its own suction.
The man you see in the video with me is my father. The most help l got was finantial, he bought me a old moped and all the materials for the project.
The heavy threeweel was later dumped, and converted back to a 2 wheel, and equipt with a G3k pellet gasifier. Later, it became a charoal powered moped,
The oilpump proved to be unsucsessful over long perions of time. The original oil nozzle was more sucessfull. But allinall, it ran (and still does) ruk good on charcoal.
