A friend gave me a mid 90s MTD snow blower with tracks. I believe its a 10/28. He blew the motor, and Im having a hard time finding one to replace it. A snow king 10 hp by Tecumseh. I did find this briggs, but I think the shaft sizes are different, and the engine does not have great reviews. I dont mind if its a small step down in terms of power.
