For sale is a new Echo 620p powerhead only. I cut the squish band and cylinder base on my lathe. I ported the cylinder, modified the muffler, and also modified the carb. If you’re interested in details, I did a build thread on this saw over on OPE Forum: Echo 620p FKWS Build I am asking $700 plus shipping. PayPal F&F preferred, or add 3% for G&S.
