My new Cub Comm. M-60 with the Kohlor 27 hp, has really impressed me, as far as torque and fuel useage. I also have a Kaw 23 hp, (which has been a great motor for me) and this Kohlor uses less fuel then it. With todays prices, This might make my motor dicision easy in the future. Starts good, great power etc. My 72" with the 28 generac uses alittle more which is understandable, especially of how much more production it does then the 60's. Only thing that dicusses me on the generac, is the hard starting at times, any other gen owners with this problem?
