That piston looks toast to me and 125psi on an engine is awfully low, 175psi is good on a machine that has been run in and is low hours.......or modified:sneaky2:

 

The exhaust can be blanked off with rubber sheet between it and the cylinder, the inlet is usually the same or using rubber bungs/plastic plugs etc

 

I am assuming you are describing a pressure or vacuum tester??? You really need to do both as seals can leak under one and seal under another!

 

 

The 50cc Dolmars usually have higher static compression in the combustion chamber than most saws, so 175 isn't high, even stock.

Those compression numbers mean very little really, unless it is low for the model in question.

125 is very low on those saws.
