So i picked up a 372xp from a local dealer late fall '12. I've maybe run 5 tanks through it so far. The last two times i have gone to use it, it hasn't started, and this has lead me to get frusterated and flood the engine. Both times have been with fresh premium right out of two different pumps at two different gas stations.. I'm figuring this should sputter with 2-3 pulls full choke, then take choke off, and one pull. Also, when its warm after being run for a bit, it takes me a good 5 pulls no choke to get it going again. Is there a possibility that no one is using premium and the fuel is going bad in the ground? I'm only thinking this because last week i poured out the gas in the saw, and filled it up with my buddies regular gas that has been sitting in his garage for over a yr, and it started right up after the flooding cleared. I'm going to stop by the stihl dealer on my way home and pick up a can of the pre mixed fuel and see if that has any effect.
