Re: engine starts blade won't spin
The large black plastic bar sticking up is a kick back safety device. Pull it back toward the handle to make sure it has not been engaged. If it is engaged the chain will not move. If that is not the problem then the chain clutch is defective. I am assuming the chain is not too tight.

Hi, I'm Peter, You may have your chain adjustment too tight. When you adjust the chain you should have it loose enough to where you can pick the chain up and there will be enough slack to where the chain guide that runs in the grove of the bar will be just a little ways down in the grove where you picked it up. If you can't lift the chain up with your fingers to do this it is too tight if you do this and the chain guide comes completely out of the groove then it is too loose. Make sure your chain brake is off also when you try to start the engine. I also pour a little chain oil on the chain and bar before I start it to prevent need less start up wear.
Hope this helps. Peter
or a to thick chain or the chain was not cleaned after use before a long time The chain may be stiff with tree resin, you have the chain anyway can rotate by hand when the machine is not on the safety brake
First, don't cut nails as you will dull the blade in seconds. Is the safety anti-kickback bar shoved into position. That applies a chain brake that can spark if you can get the engine started with it engaged. Other than that, inspect for the chain running into stuff it should not. Assuming you have put oil in the chain bar reservoir and pumped the pump a few times to get some pre-lube on the chain & bar;.
check for bent crankshaft at blade connection point. do this by removing spark plug and turn the mower on its side with carburator side up, now spin blade by hand and see if it will spin without a wobble. if it does not want to move, something else inside the engine is damaged and probably not worth fixing. if the blade does not spin true, it is a bent crank and might be able to be straightened by a mechanically inclined person without further damage to the motor. also check to see if the piston is moving while spinning the blade if it will turn at all.

Do you mean the chain won't move, or you can't get the blade off? The chain brake must be off to allow the chain to move. The chain brake handle has a housing that engages a gear attached to the chain brake inside the cover where the blade is attached. The brake must be off to remove the cover (usually held on by two nuts). The blade tension screw should be loosened to allow the blade to be removed, then retightened when replacing the blade. Tightening it pushes the blade out from the saw, so if it is tight, you won't be able to remove the blade. Hope this helps.
Make sure the blade and shaft can easily be moved by hand. First, remove the spark plug wire from the plug. Reach under the mower and see if the blade will turn or if something is stuck between the blade and the mower. Also remember that you have to hold the safety bar when you are starting the mower or the engine won't turn. It is possible that the cable from the safety bar to the engine brake has come loose. Follow the cable from the safety bar to the engine and make sure it is working.Also check whether the line from the gas tank to the engine is crimped?
Also check this link to troubleshoot your problem:-
safety switches that all riding mowers seem to have include a seat/brake safety which means that you have to be sitting in the seat or the brake must be engaged for it to start. also there is the blade engaged safety, which means the mower will not start normally with the blades engaged. if you meet those conditions check the switches themselves non safety related, do you hear a click or a clunk when you turn the key to the start position, this is the starting coil pulling in to send power from the battery to the engine starter, all safety switches will interupt power from the key switch to the starting coil if you hear the coil energize and the engine does not start you have low battery voltage or loose connection or some other mechanical problem
You have two safety interlocks that must be "made" before the engine will start.
The brake must be engaged.
The blades must be disengaged.
There may be a neutral safety too.
All of these switches must be closed to get ignition.
