Re: Poulan Wildthing 18
Hi tchild, my name is Dennis and I will try to assist you with your problem. You can get the part from Poulan parts and it will take about 15 minutes to fix the first time eight minutes the second time. In addition I might add that to remove the centrifugal clutch and the sprocket, it unscrews from the crankshaft with a left hand thread. A little trick to remove anything from a crankshaft that could turn while you want to unscrew the item, Remove the spark plug and insert some rope into the cylinder for the piston to squeeze against and you will jam the piston without damage. Glad to be of assistance. Please rate the solution because I can learn from your rating. Thank you

First, stop your engine. Check to make sure that the chain brake isn't engaged. The chain brake can activate automatically by a sudden movement or impact. You can disengage the chain brake by pulling the chain brake hand guard back against the front handle and releasing slowly. If the chain brake is disengaged and the chain does not turn; turn off the saw, then check the drive links on the chain, the bar groove and the sprocket nose on the bar. A burr on the drive links will bind the chain in the bar. If the bar has been pinched, the chain will not pass freely through the groove. If a sliver of wood has gotten into the sprocket nose, it will not turn at all. Also, look at the drive sprocket on the saw itself to see if it has a groove worn into it. A drive sprocket with a groove worn into it will damage the chain.
The P4018 has an out board sprocket, so to remove you need to remove the side cover nuts and take away the cover, the bar and the chain, there is then an e clip on the end of the crank, insert a suitable screw driver into the inner edge of this clip and gently pry off, take away the large backing washer, the sprocket will now just pull off the crank.
This could be a couple of things, if the fuel tank brather is blocke the tank will vacume, to test this try slackening off the fuel cap when the saw starts to die, if it picks up again it is a fuel tank braether issue, the other possibility is a bad ignition unit breaking down, the only test for this is to replace the unit and try again.
That is the brake ring and should fit over the clutch outer drum. If the brake was set when you pulled the cover off, it will be necessary to release the brake mechanism to get it to pass over the drum. Good luck!

Hi tchild, my name is Dennis Gladx and I can assist you with the problem of getting the sprocket off of the crankshaft of your chainsaw.
To remove the centrifugal clutch and sprocket you unscrew it from the
crankshaft and it has a left hand thread. Also a little trick to remove anything from a
crankshaft that could turn while you want to unscrew the item, Remove the spark
plug and insert some rope into the cylinder for the piston to squeeze against
and you will jam the piston without damage.
