I have a very nice 346p. It came to me with a scored piston and cylinder. I sent the cylinder to mastermind to have him hopefully save it but he said it was too scored to be salvaged. I sourced a cylinder from husqvarnaxpman. Used a new meteor piston with caber rings and put it back together. I did a vac test and it passed (-10psi for 10 minutes) as well as a pressure test. Replaced the plastic clamp on the intake with a metal clamp from a 044. Did a base gasket delete and the squish is now about .024 Saw has 180 psi compression cold and runs great. I will try to get a video of it running today. Saw will be sold powerhead only. Pm me for more pictures if you would like. $375 shipped
