So, I have done a complete tune up to this old motor. Points, cap, rotor, plugs, wires, valve adjusment, timing, and i still have a dead cylinder.... Im thinking i have a burnt valve because the valves were so far out of adjusment... Will the mg head gasket work on the j13 motor? Im having trouble finding a headgasket. And i dont want to take the head off if i cant find a gasket. Any ideas???????:confused:
