I have a Poulan leaf blower, maybe two seasons old, not used much. Last time I used it, it ran fine. Turned it off and put it away for about a month. When I tried to crank it, it won't start. I sprayed starting fluid in the carburetor and it starts, runs for a few seconds and dies. Therefore, it is apparently getting a spark but not fuel. Pulled fuel filter out of the gas tank and blew through it. Put it back in the gast tank. Still won't start. What now?

Take off the muffler and you should see the piston and ring..with a small pick push at ring to see if it moves. If no movement, you have carbon buildup from too much oil in fuel. Remove cylinder and carefully try to free the ring.
This blower is fuel sensitive! Gas and oil mixture has to be correct. Too much oil will cause carbon buildup in the cylinder. In my case my blower would not start after several uses this season. I checked EVERYTHING....spark, fuel delivery, air filter.....then checked the flywheel which has no separate key....the key is cast into the flywheel. Read somewhere about the carbon buildup so took the cylinder off and viola! The piston ring was firmly stuck in the piston groove plus the cylinder was carbon scored. I tried to gently pry the piston ring free but it was so firmly stuck, it broke. Not worth fixing. Take the muffler off and you will be able to see the piston ring....use a small pick or something to see if the ring is free. If not, proceed to tear down or throw out. I was able to see scoring on the piston and determine my ring was stuck this way. Remember the elements needed for successful ignition...fuel/air...spark....compression. Stuck ring = low compression. The last time you ran the blower the ring became stuck...the engine continued to run because of the engine rpm's but when you try to start at low RPM's, no luck.
put a teaspoon of mix oil into the spark plug hole, some times the metal starts to bind in the engine. keep the wire off and the plug in and pull the cord a bunch of times until it starts to get easier, if you need to add more mix directly to the hole then do it. hope this helps
