Nothing like the sound a "knocking rod", spun rod bearing, or broke
valve.
sounds more like a stuck valve, thats occured here
Easily checked at the tappet filter / crank breather (if this model
has one) - remove it and pull the cord...the valves should move and
easily viewed. The easy way; pull the plug wire and plug, determine
which digit goes into the plug hole. Rotated through all four
strokes: intake, compression, power, exhaust - you can feel the intake
pulling the finger, Compression stroke will blow the finger out.
