This is an original replacement part manufactured for use with handheld leaf blowers. The flywheel has magnets on its side that create an electric charge as the magnets pass the ignition module. The electric charge is sent to the spark plug to fire the air-fuel mix in the cylinder. The flywheel fits on the crankshaft by a key that aligns with a keyway on the crankshaft, this allows for proper firing timing. If the key on the flywheel is broken it can cause misfires or will not start at all. This flywheel is sold as an individual replacement part.

No start.......no attempt to start even with starting fluid. Compression was at minimums when I checked it.

Unit will have to be completely disassembled so remember (i.e. take pictures) as you go. Remove carb. and fuel tank at the same time and leave hose hooked to carb. Got to the other side and remove plastic cover over exhaust muffler and remove muffler, gasket and metal deflector. Remove carrying handle (2 screws) and the top plastic cover. At this time you can remove spark plug if you desire...........or you can wait until later.
Bottom side of unit............remove 3 screws covering and protecting fan and set cover and screw aside. Hold fan and remove nut, lock washer and large flat washer. Set this aside also. Remove fan duct and nozzle (4 screws) and set it aside. Now all that is left is the lower housing (4 screws) Remove screws and housing and set aside.
Flywheel is exposed at this point and (in this order) you will find a space and washer (washer is next to flywheel. Remove them and set aside. Gently work flywheel back and forth.......a little lubricant between shaft and flywheel will help. Shaft is tapered so it will come off with a little effort.
Next I took the two allen head bolts holding the cylinder head on. Set them aside and remove head. I removed the piston and rod assembly due to over-heating and or lack of proper lubricant in fuel. To remove the assembly the "black" cover (2 screws) on rear if engine block will have to be removed.
To reassemble everything is reverse from disassembly. I used RED Loctite on the cylinder bolts and BLUE Loctite on the Fan Nut and shaft.
Main culprit I found was the piston ring was frozen to the piston and the cylinder was scored. Compression was dismal and what I suspected was proven once the unit was disassemble.
Make sure you have a good supply or Torx screwdrivers and bits (various sizes) along with a good Allen Wrench set
Don't forget to watch for the gasket behind carb. It will come lose and may wind up on the floor when you remove the carb. Same goes for the exhaust.

1.). One of the screws holding the cylinder down sheared off at the head. The head was caught up in the flywheel and took out two blades and nicked several others. The gasket was torn as well.
2.). I had to completely disassemble the entire blower because the screw was in the back.
3.). With everything apart, I went ahead and replaced all the gaskets from the kit.
4.). I sprayed WD-40 on the post going through the flywheel and let it set for a couple of hours. Using a bench vise and a rubber mallet, I was able to easily take the fly wheel off.
5.). I had to use some needle nose vise grips to grab hold of the remainder of the broken screw and eventually worked it loose.
6.). Reassembled all the hardware. I made sure, while taking it apart, to take detailed pictures with my phone. I used those pictures and the diagrams from replacements to make sure that I put everything back together properly. I had also placed the each part or associated screw in their own containers to help keep them organized.
7.). Leaf blower works great now. $20 in parts, a couple of hours of disassemble and reassemble and I am back in business.
