I have a Poulan 2055 , 20 cc that will not start. The cord will not pull freely with the spark plug in. If I remove the spark plug it pulls freely. The muffler and exhaust are clear. Would this be a stuck valve of some sort & how would I repair ? I do not have much experience on 2 cycle motors

Re: Poulan 2055 will not start
I would recommend calling their tech line at 1-800-554-6723. But in my experience most 2 cycles don't really have valves that stick just slots cut into the cylinder to exhaust the gases. Let me know what happens please

incorrect plug in use where the plug end is hitting the piston
seizing piston ring
flooding engine allowing raw fuel into combustion chamber causing a hydraulic lock situation
remove the plug and if the pull start is normal, it is either the plug or excessive fuel
if it spins over freely with out the plug
put your finger over the plug hole and pull the cord several times to remove any excess fuel from the system
if it is still difficult with the plug removed
replace or repair
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
1st try another good plug, if no spark, remove the pull start and you will see 2 small wires and 1 thick one going to the plug, disconect the one that has a spade conector on it (the other small one should be screwed down on to the coil) refit the starter and check for spark. if none replace the ignition coil/ module as one part.
The starter housing is removed with a #20 Torx bit, then the cord replacement becomes obvious. You'll need to prewind the spring about half it's capacity before engaging the cord reel to the rewind spring. Good luck with it. These cords won't break if you use short pulls, preferably with your foot holding the right hand hold to the floor.
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.
well there are generalloy two issues with any motor. SPARK and FUEL
Remove the plug and hold it near the entry point of the plug hole so it earths to case. Pull starter cord and see if the plug has a stong spark. the should also be some wetness on the plu indicating fuel is pumping. Place finger over the plu hole and pull cord avoiding any spark but check the amount of pressure in cylinder. The pressure should be stronmg enough to push your finger off the hole
Replace plug and open the air intake and spray some AEROSTART into air intake pull start cord. If this does not cause it to attempt a start, I would suspect the coil is fused and will need replacing
check that plug is getting spark (remove plug, w/ cap attached hold tip of plug on cooling fin. pull starter rope, should see spark). if not receiving gas check filter in tank, if ok procede to carb possibly add a bit of starter fluid.
