Z,


The MVVS 1.50 engine is not available any more.
It has been superseded by the 26 cc 1.60 engine, which is available as a glow version (with a normal, or a Walbro carburettor) and a gasoline version.

Parts are still available from MVVS, but complete engines, new and used, can only be purchased on the from previous owners.

I don't have such an engine to weigh for you. Sorry.
Maybe Pé has one.
