Lobo Pup Twin Diesel

[Mechanicboy]

In my youth I started plenty single diesels but have no experience with a twin.

How you adjust two contrapistons, one is finnicky enough.

When the engine is running, adjust the contrapiston and see the oil is colored as honey out of exhaustport, do it same with other contrapiston. In case black, the engine is overcompressed.

I owned the Taplin twin engine.
