That is the way of things I am afraid no one ever reports good news its not news worthy, there a quite a few MVVS nee Evolution gassers being used on the QQ Yak that are not reporting trouble, so one assumes they are fine.

One thing seems to be pretty constant about the Evolution line of gassers. You rarely to never hear any righteous praise being bandied about for them. I think the one post above is the first one that I have seen that had anything positive to say about them.
Has Horizon managed to introduce another MDS type line of engines? I hope not because we really do need another line of reliable gassers, especially in the 50 to 70cc class.
