Pro 42CC 2 Cycle Chainsaw, 18″

My chain saw will crank just fine.  When I give it some gas, the chain will not move.  After I take the cover off and take the arm off, I try to move the drive that actually moves the chain.  It will not move.  It is frozen.  Are there any suggestions out there?  Much appreciated.
Experienced gardeners share their insights in answering this question :
If equipped, the chain brake may be engaged. Its the lever just ahead of the fore handle. (pull back on it)If the clutch assy. were frozen, then the chain would move all the time.Good luckAduz

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 :

Internal combustion engines can seize up when poor lubrication causes the piston to overheat, expand and come into contact with the cylinder. Seizure affects both 4-stroke and 2-stroke internal combustion engines, and not just in cars, motorcycles and scooters, but in gardening tools too.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the chainsaw may run stall or run rough. To unclog the spark arrestor, remove it and clean it with a wire brush. You can also replace the spark arrestor.
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.
If the clutch pads are worn out, the motor will run, but the clutch pads will not engage the clutch drum. As a result, the chain won`t turn. Make sure that the stop lever is disengaged. If the stop lever is engaged, the chain won`t turn.
A dirty carburetor, bad gasoline and low-quality two-stroke oil that creates deposits all contribute to chainsaw starting problems.
The throttle and lock safety feature prevents accidental throttle engagement. Both the throttle and and lock must be pressed in order for the chain to move.
Why does my Poulan chainsaw die when I give it gas? A Poulan chainsaw dies after you give it gas because of the clogged fuel filter caused by the old fuel. Over time, the sticky substance in the fuel will evaporate, leaving behind a thick, stickier substance. This will block the fuel filter, causing the engine to die.
The chain may not have the proper amount of tension. If the adjustment screw is too loose, the chain may not make good contact with the wood. If the chain is too tight, the chain may not rotate at the proper speed, causing the chain not to cut properly. To adjust the chain, tighten or loosen the adjustment screw.
There are many factors that can stop your chainsaw from running, including a bad spark plug or dirty air filter. There are simple problems: a broken fuel line, bad fuel, wrongly calibrated high-low adjustment screw. Also, more complex issues like a damaged carburettor or an engine compression problem.
The chain may not have the proper amount of tension. If the adjustment screw is too loose, the chain may not make good contact with the wood. If the chain is too tight, the chain may not rotate at the proper speed, causing the chain not to cut properly. To adjust the chain, tighten or loosen the adjustment screw.
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.
The chainsaw chain should feel snug but still pull freely.

Need a chain for 14in electric poulan chain saw the normal 14 in chain does not list the electric saw as one it will fit
ANSWER : Hello Jennifer;
The number of drive links, pitch and gauge of the chain need to be determined to answer your question. If you take your saw or just the chain to a local chain saw outlet a new chain can be fabricated in a very few minutes. This will save shipping and handling fees as well. While there get the numbers mentioned above. Once you have these you can likely find a low kickback chain in a local home center the next time the chain needs replacement.
The FAQs here can likely answer all your questions.

I would like to go down A bar size our two on my poulan wildthing
ANSWER : I have a Poulan Pro 295 20″.  When I bought it I also bought a 16″bar and chain and have been using those since.  They make the saw much easier to handle and are a better match to the available power.
The key dimension is from the bar’s mounting hole to its end.  At the store look at the normal replacement bar for your 18″ saw, and pick out a 16″ or even 14″ bar with the same dimensions there.  This can be easily seen by laying one bar over the other.

Chain won’t stay tight on my poulan 222 pro. I have the correct chain size. Does the bar need to be replaced?
ANSWER : No, the bar fasteners are not tight enough. If the saw is under warranty, take it to a servicing dealer for repair or instructions to correct what you are doing wrong. Good luck!
