I just got this saw last week,,and tryin to get it broke in,,,Seems to be a great saw,,cuts great,,but just hard as heck to start when ran for awhiles...Is that normal during a break in for this saw???? I bought this saw to do trim work with...My old Stihl 028 and my Pro Mac fires up with 1 pull after a warm up....Just kinda has me worried...Thanks,and I always read on this sight and always enjoy the imput on things.....
