All of the Comet TC's i've had in my life have come mounted to OHV Tecumseh's. These motors seem to have an extended crank so that the whole driver sits flush with the end. I noticed the length of the crank on my clone is 2 5/16 as is the one on another utility type OHH5.5 Tec.. how are you guys running torque convertors on these type of shafts?
