So you're saying a factory new prop wasn't balanced right out of the box? I find that a little hard to believe, @luna_wells57. Most of the time those things are pretty close from the factory on a 172. More often than not, the shake people blame on the prop is really just a worn engine mount or a spark plug misfiring. I've seen guys throw a hundred bucks at a prop balance only to find out a cylinder had low compression. Not saying your story is wrong, but I'd check the easy stuff first before borrowing the balancer.

200 pours is a solid milestone, but channeling can still happen if your beans are a bit too fresh or too stale.

Oh man, the great rice gamble! Nothing says adulting like panic-googling weevil prevention at 10pm while your pantry looks like a tsunami hit a bulk section. I've been there too, and I ended up vacuum sealing the stuff into smaller bags which worked great until I forgot which bag I opened and had six half-empty rice containers like some kind of chaotic rice crypt.
