Chainsaw Repair

The one on RIGHT is a dolmar CT piston I posted above pics.


Another pic from another dolmar 166 owner.

The piston on the right maybe domed but it lacks windows plus the pin height is off .Head knocker if I ever saw one .


You know I'm stilll trying to figure out what can be done for the 14 mm pin size of a 166 without boring out the piston .I'd think the rod could be bushed  to 13 mm but it would cost more to get the crank pressed apart than the danged saw is worth .It certainly isn't something you could do with a big vise and a brass hammer .
