3 weeks ago motor ran fine but had seen a little 2 cycle oil/gas mixture on side of the motor, tried to start it yesterday, ran for about 30 seconds and stopped, motor seemed seized, pulled plugs no water, put socket wrench on and rocked it back and forth until it broke loose, check compression on all cylinders and they are perfect. when I turn the engine over with socket wrench can feel a rough spot once in a while, was wondering if the lower crankshaft seal and bearing were bad.
