i have two discontinued OS engines and i need the high speed AND low speed needle o-rings for both engines. they are the...
OS 40 FSR and
OS 45 FSR ABC.
i think they have the same carburator - OS item # 4BK
also, is there a source for the piston/cylinder assembly for the 45 FSR ABC?

Sorry about the omission. We'd not know where you might be able to locate a piston/cylinder assembly for the O.S. Max .45 FSR. We certainly have not had any for a number of years, since it's been discontinued for so long. O.S. in Japan wouldn't have them, either.
Check the model magzines in their classified sections for dealers who sell to engine collectors. You may be able to locate parts there.
