Pro Chain Saw 46cc 20″

My Husband has a 2175 anniversary Poulan Chainsaw about a couple years old I think, and he just used it last week, but yesterday, he started it up at the house to make sure it would run, and shut it off, when he got out in the woods to cut, the Chainsaw wouldn’t start, the pull cord won’t pull out when he tried to pull on it to start it. What could be wrong with it,and how can he fix it, without taking it to a repair shop? Thank You
Experienced gardeners share their insights in answering this question :
Simply check to see if motor is locked is to remove spark plug and try to pull start. If motor turns, then he may have gotten gas in cylinder and created hydraulic lock. If moto does not turn, it is just a few screws more to take side cover off and see if rope caught in pully. In fact, you may want to take side cover off first, and make sure rope pulls out of housing, and self winds, like it should. At hat point, he can simple turn flywheel by hand to see if motor is locked up.If the motor is locked up, you can put small amount of motor oil, (half a tea spoon) into spark plug hole, let it sit half an hour or so, and then try to work the flywheel back and forth to break it free. This condition may have been caused by running straight gas, not mixed. And, even if motor frees up, it may still need to go in for repair. We have a couple of Poulin Pros at this saw mill where I work, and have had the piston lock up more than once, from guys dumping in straight gas. Sometimes we’ra able to free up piston, and make saw run again. And sometimes we end up tearing it down and repairing piston ring. Good Luck

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A dirty carburetor, bad gasoline and low-quality two-stroke oil that creates deposits all contribute to chainsaw starting problems.
One of the advantages of electric chainsaws that beginning chainsaw users particularly like is the minimal effort needed to start them. There`s no throttle to open and no cord to pull, just a couple of buttons to press or squeeze.
The force used to pull the starter rope tensions the spring against the opposing force created by the piston during compression. If the energy of the pretensioned spring is greater than the opposing force created by the piston during compression, the crankshaft starts to turn and the engine attempts to fire.
A spark plug might be defective and needs to be replaced.

If your chainsaw has a defective spark plug, it cannot create an electrical current to ignite the system. Remove the spark plug and inspect if it is dirty, cracked, eroded, or damaged. There may also be a heavy carbon buildup or a burned-up electrode.

With the choke in the “off” position, pull the engine`s crank cord through again. The engine should start in 1 to 3 pulls. Try it first without using the throttle control—unless recommended by the manufacturer.
To make pulling the cord easier, shift the lawnmower height up to start the machine, then lower it back down to your desired grass height to begin cutting.
The operator pulls the rope`s handle or grip. This causes the rope to unwind around the crankshaft and spin it. The spinning motion of the crankshaft cranks the engine. The crankshaft`s motion engages the flywheel, enabling the engine to start.
The Fix – Remove your air filter and drop a shot of MIXED gas into the carburetor intake (about a thimble full). Now go ahead and start your saw in the usual way. Your saw will likely start on the second pull but then stall. Just repeat the process until the saw runs smoothly.

If your STIHL chainsaw is going to have a problem, it`s likely to be with a worn carburetor, bad spark plugs, loose fuel hoses, or clogged fuel lines. You should also inspect the fuel intake system and ensure that there are no compression issues.

Chainsaw won’t start
ANSWER : Time to get out your trusty tool kit. Remove the side cover assembly and look at the recoil assembly. You should see a pair of fingers that when you pull the cord move toward the center. If the fingers are there and not broken, make sure they move when you pull the cord. clean them if dirty or have foreign objects (like sawdust) around them. If the fingers are broken, replace them. You should be able to purchase them from your local saw shop.

Hard to pull starter rope. It doesn’t pull smoothly. hard to pull.
ANSWER : 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!
