I have other gas engines and it would be much easier to have one can of 32:1 to use for all of them so I was just seeing if any of you were using such a mixture. I really do not think it needs so much oil, if it still had a plain bearing in the big end then maybe, but even being of ABC construction 20:1 just seems pretty excessive.
Yes, on a NOS 2 years old maybe with a "Blended" Poulan 2 stroke oil and after 1 gallon of 20/1 the con rod slop was bad so sent it in. They replaced the "cyl/piston set" free but I haven't opened it to verify. So - maybe - 20/1 isn't enough oil? Or the wrong oil? Maybe they updated it by putting in rollers at the same time?
RE oil, in the early 40's we ran 3/1, 70 SAE motorcycle oil. It worked. I did a "Whoop's!" and wondered when I saw the 20/1 knowing the rod had to have plain bronze.
