I like my NT 16 in my CEN MT2 and i like my .46 In my Genesis, for my NT 16 it have been bulit proof never a singel problem with that engine. It has allot of power and it allways start on 1 or 2 pulls.
My .46 is also a great engine , but i have only run it for 20 tanks. I love CEN engine they are very good, and always start.
