Gas Cap

If the small engine stops after a few seconds, the gas cap might be defective. All gas caps have a small vent to allow air back into the tank when the small engine is running - otherwise as gas is drawn from the tank it would create a vacuum. The vent can be difficult to see and there are many different types of vent. If loosening the gas cap a little allows the engine to stay running, replace the gas cap. It's sometimes possible to clean the vent, but on most newer engines the vent cannot be cleaned, the cap will have to be replaced.

Carburetor

If the small engine stops after a few seconds, the carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the small engine for a long time some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac. This sticky fuel can clog up the small jets and ports in the carburetor and it can be difficult to burn allowing the engine to only run for a few seconds. The only solution is to drain the old fuel from the float bowl and thoroughly clean the carburetor with carburetor cleaner. If that isn't effective, replace the entire carburetor.
