I am happy with my Alpha. I have an older generation Orange head that needed a Nova carb. I love the low end grunt and it has ample power everywhere. yes it is very easy to tune. It loves an OS P3 plug but I am not crazy about the lack of runtimes. When I am really on the gas its a 7 minute engine on a large track and that just wont do for me. As Much as I like it, especially the price, I need more runtime which can be had from a few other engines that all fall in the same price range. I dont think I would buy another one
