If the engine is running on half choke then it is starving for fuel. Either there is a clog from the tank to the carb, the needle is sticking, the float is adjusted incorrectly, the carb is dirty or mis-adjusted, or you have an air leak between the carb and manifold or the manifold and engine. I would check for an air leak first because it is the easiest to do, followed by a fuel flow check from the tank. If both of those fail then the carb needs to be gone through again. carl
