Replacement engine for Stihl MS180

[Koper]

I have several MS180 saws in my barn, they are handy saws but I wouldn't go through the effort of replacing the piston or cylinder. The cost/time balance isn't working in your favor.

I've seen on Aliexpress that a complete engine for the Stihl MS180 sells for about $27, which bring it back to my first question - if any member of the forum ever tried it? you've mentioned that you have several saw of this model in your barn, so I guess that you use them more intensively, as I wrote - I only use it every once in a while, so maybe it's worth to fix.

Will the flywheel turn by hand or with a socket on the nut with the sparkplug out?

I didn't took it apart yet, so I couldn't try to turn the flywheel, but even without the spark plug - it doesn't move by pulling the cord starter.

Which could still be simply a broken starter assembly.

Unfortunately in this day and age a saw like the MS180 falls into the disposables category. I was curious what parts would cost and found this. Good luck.

I noticed a seller on ebay also had a complete 180 engine with crank and free shipping from the USA with 2 year warranty for $32.

I've seen (if I'm not mistaking) that there are two versions of the MS180 engine, one with 8 mm pin and the newer version with 10 mm pin. are the two versions interchangeable? I guess that mine chainsaw is the older version, so if I'll have to purchase a new engine and it will be of the new version - will it still fit? and if you can enlighten my eyes on which pin we are talking about?
