I would like for you to try something.

Technician: Donald, Small Engine Technician replied 11 months ago

Remove the spark plug wire on the left side of your engine, then check to see if your engine will start with only one spark plug wire attached.

Ask Your Own Small Engine Question
Customer reply replied 11 months ago
No it will not start
Technician: Donald, Small Engine Technician replied 11 months ago

Thank you for checking. Re-attach the wire to your left side spark plug. Remove the spark plug wire on the right side, then try starting your engine again.

Customer reply replied 11 months ago
no won't start
Technician: Donald, Small Engine Technician replied 11 months ago

I would like to confirm something. Are you saying that your engine will not not start without both spark plug wires attached, regardless of the wire that is removed.

Customer reply replied 11 months ago
it will start only if i play with the choke, then smokes from exhaust bad
Technician: Donald, Small Engine Technician replied 11 months ago

Do you have some plastic zip ties?

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 11 months ago

There is another procedure you can try to help determine if one of your cylinders is not functional. It requires you to remove the spark plug wire from your spark plug while your engine is running.

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 11 months ago

You can put a plastic zip tie on both of your spark plug wires, to aid in safely removing your spark plug wires during this procedure. Remember to loosen your spark plug wires prior to doing this procedure.

Ask Your Own Small Engine Question
Technician: Donald, Small Engine Technician replied 11 months ago

Start your engine and while your engine is running, remove the spark plug wire from the spark plug on your Left Cylinder. If your engine continues to run, this means that your Right Cylinder is working. If your engine shuts off, this indicates a fault in your Right Cylinder.

If your engine continues to run, reattach your spark plug wire, and move to your Right Cylinder. Repeat the procedure above. If your engine continues to run, this means your Left Cylinder is working. If your engine shuts off, this indicates a fault in your Left Cylinder.

will have to check later since it is getting dark outside
Technician: Donald, Small Engine Technician replied 11 months ago

No problem. Take your time. We can continue after you have had an opportunity to check this out. This will give you and me a good starting point for troubleshooting.

Technician: Donald, Small Engine Technician replied 11 months ago

There are a few things that could be causing our problem. A blown head gasket, dirty carburetor, low compression, etc.
