Blowers

I have Weed Eater FB25 Blower that has failed prematurely. The authorized service dealer said it was because of the fuel used. I used exactly what the manual prescribed. The manuals that come with the unit are wrong according to service tech. Because of this I feel Weed Eater should do the right thing and replace my unit. It cost more for labor to repair it than it cost to buy new. I feel that is a ripoff to the consumer.
