No its not in a thiokol, but very simular. Weasels were a military all terian tracked cargo carrier built by Studebaker during WW2. After WW2 my weasel was given to the Norwiegan army. It was sold as surplus and returned to the US in the erly 80's. These weasels were bought by private individuals as snow mobile trail groomers, ski hills ect. It was very common to replace worn motors for the ford strait 6 for the extra power and parts availibility. I use mine to get in and out of my hunting camp in winter and playing in the snow.
Getting back to my question, I have a Carter YF6050S that needs rebuilding badly, I can get a rebuilt Carter YF6057S very cheep. Will it work? Is there a better carb without changing the manifold?
By the way, I'm buying a 1963 Thiokol 601 and the motors is a 223 ford.
