Neal, it sounds like you are correct,move to the head of the class.I'd pull the valve cover and have a peek,turn to TDC compression stroke #1 and look for excessive clearance on the valves.My guess is the intake stem and guide are jizzed up with crud.You can turn the engine over and observe the valve action,you will likely see something obvious, valve staying open and the push rod getting loose,broken spring perhaps.You might get away with spraying the jeepers out of a sticky stem with carb cleaner and running some ATF in the crankcase,don't eat a good meal before you pull the valve cover,the sludge you see may make you vomit.
