Hello

I would like to know what are the external difference between these two engine.
The engine of a HUP I am mounting, seems to have some external difference with the engine describe in the good web site of PHIL WATERMANN.

Among these difference , I have to note that I have no supplementary oil filter at the top of the engine, and that the command of carburator is between the intake and exhaust manifold (red swallow) .

Best regards Serge
