I have never struggled to find a decent cylinder and piston for a saw. Yet now I do with this 231. Secondly no dealer can find me some caber rings for this saw. I have had to get some from Greece. Now I bought this saw for around $50 dollars in need of a new p&c, can I find a decent spare... no. Had to refinish the cylinder and the rings I got with an AM piston don't even fit in the grooves, they are 0.2mm over spec in thickness. Sod this crap, I am going back to my day job... is it me or are the 231's rare and was this because no one liked them?
