Over the winter I am going to be maintaining and prepairing my equipment for the upcoming season. My #1 Concern for issues is with my Husqvarna145BT Backpack. I had started to run it the other day to run the remaining gas out of it when I notice the gas/oil mix was leaking out of the tube that transports the gas to the engine after you prime it. Does anyone know why this is or how I should go about fixing it? Also, do I need Husqvarna Spark Plugs/ Air Filters when I am going to put new ones of these in or can I go to a local store like Home Depot and pick any 2 cycle Spark Plug and Air Filter up? Thanks.
