Try finding an MVVS engine in the US. I have an old .40 that I bought when Morris was importing them. It's about the same for Rossi. I had a Rossi .40 & .45, but they were more trouble than they were worth. The ones I had 15 years ago were worse than some Chinese engine for holding a low end needle setting. It used to be common in pattern circles for the guys who flew Rossi .61s to see the low end needles covered with epoxy to keep the setting. I did see one site that sold Rossis, but their price was out of sight. Those two engines may be great in Europe, but they a re really non-players in the US until they find a good distributor who'll stock parts and keep them in stock for a reasonable price.
