If you buy one cylinder’s set of these piston rings 8 times,

You will save $12.21 over buying the set for all 8 cylinders.

i care.

i’m not nearly skilled enough to ever purchase these or build at this level. but i care.

So question. Is the squiggly bottom rings for better oil adhesion to keep the slippery stuff where it is needed? (I’ve only ever rebuilt a one cylinder tiller)

Interesting. Also, FYI, the rings in the picture are installed poorly. The gaps shouldn’t ever line up.

will they not rotate around on their own as it runs? IDK maybe I fucked up then(see previous post: I only have rebuilt my tiller)

There is some debate to that. But conventional wisdom, and personal experience, tell me they will not rotate a significant amount. However, for your application I wouldn’t worry too much. Performance lost and extra oil burned well be nearly nil in your application.

The squiggly ring is usually referred to as the expansion ring, it’s adjacent straight rings being for oil control. Basically the expansion rings keeps the oil rings apart and stable.

Your math skills are clearly better than at least 95% of the population of North America.

If you need/want scary, I recently talked to a mortgage banker that appeared to lack basic fundamental math skills. No wonder this country is so screwed up.

Correct. At least, as far as Toyota is concerned, the repair manual for my car had pretty specific orientations for the gaps on the piston rings. They did not overlap at all.
