Hey all,

I want a new engine for my Avistar so it will have more "umph" or "get-up-and-go" to it...plus I am sick of buying those needle valve assemblys on my OS 40 LA. (bought 5 so far at $8 a piece, $40 on assemblys! and they all broke) also, I broke the carb and the crankshaft had a crack in it from my last crash so...here are the contenders...others welcome...and what do you think of the remote needle versus the needle on the carb?...

And would the remote needle on the .50 SX break like the "train" on like a OS 40 LA?

Thanks for all the help,
