Greetings. I have this old silver fox 606 with a robin motor on it. It has been outside for years. I am going to put on a harbor freight motor as I did a Murray go kart and it works great. My question I think is a simple one but AI and all that are not being helpful. The motor in the torque converter and the front and back pulley and belt and all that are destroyed from rust. The thing won’t even roll. I want to replace the torque converter. I don’t know what’s on it with like 30 T torque converter work? It has 60 teeth on the big sprocket and 9 on the small.
