I bought it new last year and used during the winter to clear snow. It turned off towards the end of last winter, so I assumed it ran out of gas and didn't need to use it after (I did not put in any fuel stabilizer), so I simple put it away. When I pulled it out this year I initially put in stale gas (~6 month old) & and over filled oil (gas & oil are separate) this season and it didn't start. I have since tried numerous things like use the electric starter instead of pull cord, siphoned out all the stale gas and replaced with fresh one, drained the oil to proper level, replaced the spark plug. I tried spraying starting fluid in the spark plug hole and it seemed to fire up for like a 1/2 second. It still doesn't start. What more can I try? Also I forgot to mention when I press the primer bulb all I can hear and feel is air i.e. no fuel being primed.
