Well the engine just won't hold it's tune. I think it's at the end of its life. Unfortunately the novarossi mentioned i simply can't afford everything for at this time, So that's a next year thing. Considering a Mach 2 .28 but I'm getting mixed reviews on the net about that. Also possibly a .21but I forgot which one I was looking at. I want a good all arounder, something with a quick spool up, good power on the low end and good power to get good top speed. Any suggestions?
