I did catch that and had something typed-out for my last post, but didn't want to end up with a wall of text.

He's self-aware enough to know he's a dumbass, but not enough to realize that he's taking all this personal risk to make something that has no purpose. As far as I can tell, it's a conceptual combination of tire balancing beads and a Fluidampr (correct spelling). Neither of those things has any application on the flywheel of a small engine. The flywheel was already balanced and a single-cylinder crankshaft is too short to develop harmonic vibrations that need a damper.
Shelby, you WTR and me all know that the flywheel spins too fast for balancing beads. Let alone 00 buckshot in tygon tubing. Tires rotate at much lower speeds with less centrifugal force. Add in oil to the mix so that they can’t move freely and you just doubled the recipe for disaster. If he’s that worried about balance than balance the crank, rod, piston and flywheel all together. Although I don’t know how you’d do it with a one cylinder engine with a short stroke.
