Sachs Dolamr 120 with low compression

[sawjo]

I have a Dolmar 120 with a curious situation. I got it to fire for a couple of seconds with mix poured into the carb and then it was a no go. Seemed to pull a little easy for this saw so I checked compression with a good tester and got 125psi. Pulled the jug and found almost nothing. No scouring, stuck or broken rings and just barely a carbon "stain" on roof of piston. The psiton skirts showed some wear as if some of the chrome was gone but nos sctatched at all. Anyways there are golf piston sets available on e-bay, but the one listed for 120 is 49mm, must be for the super. There is a 47mm set avilable for the 119, will that fit my regular (47mm) SD120?

I just replaced a 120 with a 119 set of rings saw had 125 compression replaced rings and now 150 compression
