RE: dealer
Rick,
The MVVS 2.5 cc engine (.15) is still on offer and you can get it from Pé Reivers, David Moen, or from me.
Some of us may have it in stock, while others may not (this means a longer wait).
There is no MVVS dealer in the USA.
You'll have to send your request by E-mail; not over the pages of this forum.
The .21 (3.5 cc) has been out of production for the last three years (the .25 and the .28 are still available).
