The blower will need to be checked to see what is wrong. Start with compression, should be 125-145 lbs/in Check spark with a spark tester and make sure to use resistor plug. Next, make sure the fuel lines are in good condition and not cracked or leaking. If the unit has set with fuel in the unit, chances are the carburetor is clogged and the fuel lines are damaged.
SOURCE: how much oil I have to mix with gasolin for
There is a very easy way to do this. Go to your hardware store and buy a 1 gallon gas can, also purchase a 3.2 ounce bottle of 2-cycle oil, put a small amount of gasoline in the can and pour in the entire container of 2-cycle oil, shake the can for a few seconds and then fill the can the rest of the way and voila, a perfect 40:1 mix. I know there some out there who will tell you you have to specifically use Husqvarna 2-cycle oil and if you want to that is fine, but truth is, any brand of 2-cycle oil will be fine. Just make sure you get a 3.2 ounce bottle for one gallon of gas...your local hardware or lawnmower store (or Home Depot or Lowe's) has that size container of oil in stock and on the shelves. Cheers!

Hi and welcome to FixYa, I am Kelly.
The symptom your describing is most often caused by the primer bulb/pump getting a pin hole in it. See this link Item 17: (PN 544363901)

It can however be caused by diaphragms that have failed inside your WYA-79 carb. If you do not have a primer bulb problem the next step is to rebuild the WYA-79 carb with a diaphragm kit.
net IMAGE search using this: Walbro "WYA 79" "Carburetor Kit" They average $13.99

Dried and cracked fuel lines can cause the same symptom you describe also.
Thanks for choosing FixYa,
Kelly
