I guess I'll contact Dax next.
My recommendation would be to order a 66cc Lower from Dax and the order the entire upper from boygoesfast, clean up the intake and exhaust port just to remove any burs from casting which all of the jugs have that I have ever bought, and build it up from those parts and you should have a really good running little engine in the just over $100 range.
Bottom of this page and you'll see the Lower listing
And here is the link to get to the upper engine kit from boygoesfast
This is the route I would go unless Dax happens to have and entire set up that he just hasn't listed on his site.
