do you really believe cen when they tell you that the engine in the genesis have 5 horsepower? take a look at
www.osengines.com and compare hp ratings to the 46 vx-df airplane engine. that engine is the same size and the rpm is 28000 which is a great deal more than the cen engines 22500. how can it be that the cen engine generates 5 horses when the os of the same size is only rated at 2.5 horses and that is with even more rpms than the cen engine. it just makes me wonder??? I might add to that that I did own a genesis that dissapointed me a lot, both power wise and especially quality wise . luckily I got my money back from my lhs . take in mind that the carb on the cen engine is only 7.5 mm, thats less than most 21 engines pluss the pipe on the genesis isn`t exacly a very well designed one from a performance point of view
