Thanks for this video! Yesterday as I was finishing up the big bore kit on my 372, the bottom piston ring broke as I was installing it. I remembered that I once heard you say something about running "just one thin ring" on a two-groove piston, so I decided to just proceed and put it back together without a bottom ring. I want to give you credit for the prompt to keep me from quitting the job, and am happy to report that the saw runs really nicely. Today I sought out this video to confirm what the memory had told me, and now I've got the courage to keep running it without fear. Thank you!!!

I usually order the meteor 371xp single ring piston kit to save the work or the 268 so I can work it and work the squish band up and make a nice combustion chamber and squish… I started putting my Caber rings in the middle of the power zone between the squish and the top of the exhaust and adjusting the ring gap so that there’s a little more space between the closedown tips on the ring… cool tips dude! Keep on Truckin!!! 😂👍💪✊❤️🇺🇸

I also ran across a 272K 50mm P/C set off of a concrete saw that looks pretty good and the smashed cylinder piston is loaded with the factory ridged side skirts intact!

Awesome video Ironman!! I’m definitely glad to see some new things done on saws that people over look when trying to build a saw!!! I have a 2159 jonsered saw with a 20” bar and a 24” bar!! I would really like to figure out the best way to improve the Hp and torque on my saw!!! I would definitely like for it to be about a 70cc saw because of its weight!! I’m a shorter guy at 4’10” and have a bad back!! So a heavier saw is definitely out of the question!!! I really like the 2159 saw but I really think it needs a muffler mod and a few more cc!! What are your thoughts on that and what way would you go???

@sagebrushhillbilly4655

It would have never occured to me to remove material from those rings to reduce tension. That is ingenious. Something I have recently learned about modern auto engines, especially Toyota, is that a guy had better be religious about changing his oil. Don't buy into that 10k mile crap. Do it every 5k or 6 months, whatever comes first. The fine grit that accumulates in your oil can cause your OIL rings to stick in the grooves of the piston, causing oil blow by and thus oil consumption (burning oil). This is all because modern auto manufatueres figured out how much you can gain by running low tension rings, and thats what they do. More power, better feul economy, less emissions etc. To your point... RING TENSION MATTERS.
