I just bought a 60. The serial number says its a 41. It has oliver writtin on the axle and nose emblem. The engine shows a Cockshutt tag and the louvers are red with green back quarter panels. The grille is red also. These colors are well worn, not a restoration from the past. Did they interchange cockshutt motor tags with the olivers?

What is the best thing to use to clean out the gas tank with old gas that has turned shellac? I assume the carb is the same state.


Thank you
