Someone please tell me this isn t too serious !! The 1982 Aq125a I have been restoring runs smooth and great......until about 3500 rpm's and up. At this point a rattle begins in the engine ( sounds like pebbles being dropped in a sauce pan) It continues until I pull back a bit on the throttle. I think its sounds like an electrical spark going crazy, My brother says most likely the valves. It has new plugs, wires, starter coil, rotor, points and condenser. Any advice on this and cost would be appreciated. Thanks Gan
