A:

Thanks for the inquiry and for being a valued member.

I am sorry to hear of the starting issue you’re having with the trimmer. I know how frustrating that is to have happen.

There are three basics the engine needs: Ignition, Compression, and Fuel.

First, go back to the spark plug. Remove the lead, or wire, that connects from the engine to the plug. Remove the plug and put it back in the lead. Now position the lead so the metal end of the plug is against the engine or another clean unpainted metal ground point. Keep your hands away from the plug so you do not get shocked, and have a helper pull the rewind start. Look for sparks at the end of the spark plug. Look carefully as it might be hard to see in sunlight or other bright lights. If there is spark there then you have ignition, the first of the three basics. If not, the spark module will likely need replacement.

The engine should have been spinning over faster once the plug was removed and you should hear air rushing out of the spark plug holes in puffs. You could even try putting a thumb or finger over the plughole to see if the pressure pushes your finger off when turning over, just be careful not to touch the grounded plug so you do not get shocked. If that all happens then you have the second ingredient, compression. 

That leaves fuel. Check the tip of the plug you just removed, if fuel is reaching the engine there should be some residue there and it should look somewhat wet. If you used your finger to check compression then you may even see some residue on your finger. If there is fuel here, your problem may be old fuel or a timing issue. Try putting a small amount of good fuel into the throat of the carburetor and try to start. If your problem is fuel related only, the engine should now try to start, or even run, until the fuel you put in is gone. That would indicate the fuel supply is being stopped in the fuel tank, fuel line, fuel filter, or carburetor.

Q:

how to change the starter in 358791050? 358791050

A:

Thanks for the inquiry and for being a valued member.

To remove the clutch, you will need to stop the piston from moving. To do that, remove the spark plug and fill the cylinder hole with some soft rope. Leave enough sticking out to pull it back out once done. There will be a Torx 20 or 25 screw in the center of the clutch that will need to be removed once the piston is stopped. Once the clutch drum is removed, you can use an adjustable spanner wrench or channel lock pliers to unthread the clutch from the crankshaft.
