Re: my poulan wont start any suggestions
Plugged fuel line or carb due to sitting with fuel in tank. Drain tank and back flush line, changing filter if there is one. Inject some compressed air into fuel line from carb.jet screw hole, thus blowing out line toward tank. May have to also use some carb.cleaner in same area.
Prevention: Always shut off fuel line and run carb dry before storing unit. If storing a long time, remove all fuel as gasoline will not keep long, esp. in the carb.

Try starting it with the air filter removed. If it starts, clean the air filter. It could also be the fuel filter. If you replaced all the fuel lines, make sure you didn't get the oil line mixed up with a fuel line
quick check would be to pull muffler from engine check the screen if the screen is ok start engine if it starts without the muffler the muffler needs to be replaced.if it still dont start do pressure and vaccum checks on carb.
Do a basic test first, remove the top cover, pull the earth cut out wire from the terminal on the ignition unit ( this will iliminate any problems with the switch, or wires ) now try for a spark, remember that they work off speed of rotation so give it a good pull, make sure you use a good clean plug, well earthed against the cylinder. If there is still no spark, you will need to replace the unit, part no. 530039143
When you replaced the spark plug, did the plug show a snappy, blue spark when the engine was pulled through smartly? If it did, check for a plugged fuel filter, air cleaner, and muffler. Check the fuel lines for condition. Make sure the carburetor fasteners are tight. Does the primer pull fuel into it? Is the fuel mix fresh? If still nothing, try spraying some starting fluid into the cylinder through the plug hole and pull through. If pops several times, the carburetor may need to be disassembled, cleaned and adjusted. Hope this helps!
start saw when cold and work it hard. if it stalls or quits remove spark plug and hook the plug wire to the plug and ground to the cyl head have switch on and pull the start rop briskly a few times or use a test plug. if there is no spark disconnect ign switch from from the ign wires and pull rope a few more times.spark?= replace ign switch,no spark until engine is cool,replace coil.
Look for a pinched/bare stop-switch wire (I assume that you don't have spark now). Also, check the ignition coil core gap to the flywheel magnets (I use card stock to set the gap). Make sure the plug wire was not damaged again.
Take the wire of the spark plug,and see if it shocks you when the cord is pulled.If not there may be something wrong with your coil.(loose wire for example)If it does shock you,you may want to check out your piston rings,or the little air/fuel mixture valve between your carburetor,and cylinder.
Check fuel lines for stiffness & cracks'
Replace filter,plug,and fuel mixture.
If your lucky it might run.
If not check spark .
If spark is ok you may need to clean and rebuild carb making note of screw settings.
Also pull muffler and check for carbon build up.
