I guess the bottom line is after at least 5 gallons of gas through it, its running even better than before. Turned out to be a useful and fun saw. NOT quit ready to call it a reliable build yet...or hand it over to those in my test program...but I am ready to call it a steady saw in my work saw rotation. Just have to decide what saw gets knocked out of the pocket. Think UOMS ( 560 ) is going to be semi retired until I feel lousy again like last year....this season those 372's are about right for me.
