Starter rope will not pull. Will pull smoothly

Remove plug before trying to start pull a few times with plug out you may have quite a bit of fuel exhaust from spark hole then reinstall plug and try starting. Sometimes fuel runs into head above the piston (especially in hot weather) causing the piston trying to combust a liquid. If you leave fuel cap loose in hot weather it will help prevent this.

1) Remove the muffler and check the piston/cylinder condition
2) Spark plug color: if it is silver, you have overheating aluminum transfer from piston to cylinder

That is a good and bad sign. When a motor wears out and looses compression it gets very easy to pull. New motors should pull hard and be choppy or seem to "lock" however - you *MUST* carefully review your fuel mixture to ensure you are adding enough oil to the mix - if you used straight gas without adding oil you will burn the motor up and experience difficult pulling. Simple test - remove the spark plug - give it a good pull it should be liquid smooth with no binding anywhere on the pull. Report your results.

try using the de-compression button when starting, will do the same as removing the spark plug but without removing the spark plug.

Failing that, remove the starter cover and check starter cord for daage or signs of snagging.

Make sure the brake is off and retest. If brake is off and still difficult to pull, remove the side cover, chain, bar and retest. If still not right (remove sparkplug), remove the muffler and make sure that the spark arrest screen is clean and verify that the cylinder and piston look clean and smooth by looking into port. You can clean the cylinder by spraying wd40 and pulling the rope untill it all comes back out. Verify that the rope pulls smoothly before you reinstall the spark plug. If all looks good, reinstall muffler and retest. If the compression is normal, it should be rather hard to pull thru the compression stroke. Reinstall bar and chain for final test.

It could be a few things, completley flooded,starter pulley tight on its pivot post, the ignition unit too close to the flywheel and rubbing, or the egine has partly seized, remove the starter housing, with it off the saw does it pull freely? check the air gap between the coil and the flywheel, this should be 0.3mm, turn the flywheel by hand with the plug out, does it turn freely? if not remove the muffler and check the condition of the piston through the exhaust port.

Take the spark plug out--does it pull smoothly now? If not, the pull cord may be the wrong size or it is damaged and/or doesn't rewind correctly. Does the machine have a compression release? If so, it may be plugged with carbon. With the spark plug out, pull the engine through several times briskly with the throttle open and the choke off to expel any excess fuel from the crankcase. Hope some of this helps!

Pull the plug; maybe it will turn; I think piston melted to the cylinder. From your question start with 3.
Starter Handle difficult to pull:
1. Remove the starter cover. Does the starter operate smoothly? If yes, reinstall the cover and continue with 2, if no repair starter.
2. Is the saw equipped with a decompression valve? Yes continue, no proceed with 3.
· Leave the ignition off, set the valve and pull the starter.
· Pull gently to release the valve. Is there a difference in the effort required?
· If yes continue with 3, if no repair or replace the decompression valve.
3. Was this saw perhaps operated in a lean condition (metal transfer from the piston to cylinder wall)? This may be caused by many things including but not limited to; leaky intake connections at the engine or carburetor; leaky crankcase seals; cracked fuel delivery lines; running on gasoline containing no 2-cycle oil.
· Disconnect the spark plug wire and remove the plug. Remove the muffler (clean it and the spark arrestor before reinstalling), hold a light at the plug hole and inspect the cylinder through the exhaust port. Is it smooth and shiny or does it appear speckled with dull gray spots or smears?
· Pull the starter slowly, inspect the piston as it rises and falls. Is it a dull gray without scratches and gouges?
· Hold the light at the exhaust port and look through the spark plug hole, inspect the cylinder above the exhaust port. Is it shiny and smooth or speckled with gray spots or smears?
Any spots or smears on the cylinder or deep scratches and gouges in the piston indicate the saw was operated in a lean condition. Repair of this on a home owner quality saw often exceeds replacement cost. A repair estimate by an independent saw shop should be considered.
4. The last likely possibility is the saw has jumped timing. This problem or any not discussed is usually beyond the ability of the operator to repair. Please take it to a good local saw seller/mechanic for a written diagnosis before authorizing any repair.

PISTON COULD BE SEIZED DUE TO LOW OR NO OIL MIXTURE,ALSO IT COULD HAVE FUEL IN THE CHAMBER,FIRST REMOVE SPARK PLUG--NOW TRY TO PULL IT--HINT,STICK A SMALL SCREWDRIVER IN THE HOLE AND SEE IF THE PISTON RAISES AND LOWERS,,IF IT WILL RAISE/LOWER BY MANUALLY TURNING THE CRANKSHAFT,THEN THE PROBLEM IS IN YOUR INNER PULL ROPE ASSY.(THERE ARE DOG EARS INSIDE THAT SPIN OUT AND GRAB THE FLYWHEEL WHEN IT TURNS)

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.
