i have a wisconsin AKS, 1948 year. when turned over, the tappet for the intake is working correctly, however the exhaust tappet is moving slightly, but never touches the valve stem. also, with every exhaust stroke in the rotation, it binds slightly, then makes a slight "twang" inside the engine, then keeps turning over normally. i think it could be a broken camshaft if that is even possible? i have no experience with these old wisconsins, but have alot of small engine repair in my background. please advise me on the possibilities of what this could be, before i open up the engine. thanks- Jim.
