Unknown Stihl Piston

[hautions11]

An Ebay item that the owner does not know the application for a piston cylinder set. He says 066???

The part number is # 1122 020 1210 I show a 1209 as 066 piston cylinder.

Who knows what a 1210 PN is for? Thanks.

The 066 piston AND cylinder has been revised a few times... and to make it confusing, Stihl often revises numbers DOWNWARDS for later models!

The -1210 was superseded by the -1209 in 1998. The -1210 was the first version with a decomp valve and replaced the -1208 (non decomp) in 1995.
