The malossi is a pretty good deal. 1977 has them in stock and the come with a jet, and a drill bit for other jets, plus other random stuff like copper crush gasket and lots of stickers.
Its cheaper than the DR. I have run the DR and like it a lot. I have never run a malossi, but I hear they are just as good.
I have a brand new malossi kit I want to sell if you want to buy it. It still has all the bits and pieces including the jet.
Come to think of it I think I have a notched variator around here if you want to buy that too.
