What does the magneto do? It has to be grounded out to kill the engine.?? With single cylinder Briggs engine, valves may need adjusting, or if the compression is over 100 psi the compression release on the camshaft may be broken. If the compression release is broken , it makes engine hard to turn for start, and the camshaft has to be replaced.
