Ok let's start by asking this do u have spark ? If yes then u have a fuel issue ethnol fuel starts going bad in 30 days just replace the carburetor and use non oxy fuel and u will never go through this agian I guarentee it !!
3 most common possibilities: Most gas mower carburetors have a tiny hole for the fuel to rise into the vacuum venturi throat of the intake. The hole in this riser tube which goes down the center of your float chamber to the area where the fuel sits in the bowl is only about as big as dental floss. Take the tine of a wire brush to clear it of crystallized or varnished gasoline and oxidized pot metal tube crust. When they make stainless carburetors, it will eliminate half of the heart attacks caused by this problem. Additives and condensation that settle out in old gas also can lead to clogging. Another very common problem is shearing the aluminum alignment pin in the top of the crankshaft when the mower whacks a log, root or rock. The inertia splits the alignment pin in half and throws spark timing off. So it backfires or won't run. Also check your spark by grounding the fat end of the sparkplug with a jumper cable to the engine casing, leave it plugged to the wire and pull the cord to see if it is firing. Keep spark away from fuel. Ignition points in some small engines get crusty when sitting in humid conditions. So they have to be filed clean of oxidation for proper contact and sparkplug operation.

Hi Patti, If you can not pull the cord more that what you said, try removing the spark plug and see if that makes a difference, if not, leave the spark plug out to prevent accidental starting, raise up the front of the mower and see if you can turn the blade if not...it only gets worse from there. If you can't turn the blade from under the mower, the engine is more that likely seized up, sorry

You need to check a few things. The spark first, you need to check if it is running correctly, does it have spark, by doing this: take out the spark, put it against a metal surface and pull the pull start if it spark, your good if not you need a new spark plug. Clean out your airfiilter it migth help too. Buy some carb and choke cleaner squirt it up theough the airfilter hole, and start the engine, this will clen the carb. yOU MIGHT NEED TO TAKE OUT THE CARB AND CLENA I OUT THROUGHOULY!!! Try that and it whould work after all these steps!
IN your problem it might also be for some reasons like the crankshaft is bent, that damages the motor internally and cannot be fixed, hppens on older mowers. and is caused by when you run over twigs and branches andything hard!
