Help with an MS 460 rebuild

[Let her rip]

Hi forum, I am rebuilding an MS 460 with a seized up piston and from what I can gather the saw should have a 52mm piston but it has a 44mm one.... The cylinder head is an aftermarket Chinese thing from XinLei, and it says 52 on it, but the piston is definitely 44mm. Is it possible someone put the wrong cylinder and piston in it? The hole in the crankcase is definitely much larger than the piston. Any advice much appreciated!

You'll do better posting this in the general Chainsaw forum, this is the Milling forum.
