Husqvarna bt 150 blower only 4 years old. it has about 10 hours of run time. only use it a few time a year. always drain gas at the end of fall. last year it started to bog down after it was warm. to the point it would not stay running. i had a three year EXT. warranty so i took it back to LOWES. And they sent it out for repair. the repair company called me and said they replaced the coil pack. they said it was heat soaked???? they also replaced the fly wheel???? I started using it this fall and it is doing the same thing. after it warms up it bogs down when pulling the trigger. and it eventually stalls out. this should not be happening so soon. HELP HELP Cleaned Carburetor out today. 10/24/15 and it still bogs down?????
