A friend of mine gave me this engine and I am not sure how to hook up the fuel tank. The engine has 3 hose bibs for hook up to the fuel tank. One is on the muffler, One is on the Carboerator, and the other is going to the crank shaft area. Could you please give me some idea of which one goes where? I know the carberator one goes directly to the fuel tank, but the other two ????????

The line from the clunk in the fuel tank hooks to the carb
the "vent" line from the tank hooks to the muffler to pressurize the fuel tank for better fuel feed.
The line from the bottom of the crankcase is a drain line to vent any blow by and to drain the excess oil and fuel that collect in the crankcase. you may use a SHORT length of fuel tubing to get the drool to a convenient spot, but DO NOT plug the line. it is designed to breathe to the atmosphere.
Thank you very much. That is great information.
Despite difference in looks, operation is similar to that of other O.S. four strokes - down load manual =
