bought a stihl bg85 blower. bummed me out when i found out i had to go through a break-in period. i can't see a reason why this would be a problem. start it up, secure from moving around and set throttle to half power position. run the unit the required # of tanks of gas. since this is my 1st 2-cycle power equipment product, i thought i would see what your thoughts on this subject might be. slicey ps just could'nt help gunning it a few times on some leaves. holy moly, this thing can BLOW!
