I have managed to get the piston moving again and it turns over on the rope but compression has gone.

Both the 48 and 50mm piston and cylinder will fit that saw.
The standard 038 AV had 48mm piston.
The 038AV super had a 50mm piston and the 038 Magnum had a 52mm piston. All with corresponding bore sizes.

I have the AV super but I read somewhere on here that its possible to put the piston and cylinder off the Magnum (which is the same as the MS380 I think) onto the smaller ones. Pretty sure you have to elongate the cylinder stud holes in order to fit it on though.
