While mowing hit a object and engine stopped. B&S 18.5 two years old. First thought was timing. Pulled flywheel and key intact. Adusted the valves(ohv) 1/4 past tdc as specified.
.003-.005 and .005. Spark pluk fires and is getting fuel, but will not start. I amd not an expert, but I have worked on a few mowers in my time and this one has me baffeled. I need some EXPERT advice. HELP and thanks in advance. chuck35
