I have had this blower for 3 seasons now and it has really saved me alot of time on cleanups in the spring and fall. Today in the middle of a cleanup the power slowly went on it. Tried starting it back up and nothing. I run 93 high test gas and have never had a problem until today. Always would start on first or second pull. Tons of power also. Took it to my dealer before they closed this afternoon. Not sure what the problem is. I have been looking at adding another backpack for this fall and was going to get another BR600 but not sure now.
