Hi all. Got a question for the more experienced folks than me. On my first Stihl rebuild. An MS290. Model year 2011. Yes... not really worth the time, money or effort but it is for my uncles brother. Was said uncles saw but he passed away 9 yrs ago. So a bit sentimental value I guess.
Was gonna assemble today but took out the new Stihl brand crank seals and see a bit of difference. Do I have some really old NOS seals here for like an 029 or are they the wrong seals? Both seals have the OEM Stihl brand name and part number but differ in construction. Would I be ok to use these "old style" seals or should I get the style like what came off it originally?
Old seal on left and new on right. Thank you in advance.
