First thing you may want to clean the carburetor.
Problem: Engine starts easily but dies after a few seconds.
Possible causes:
1. Fuel tank is empty or shutoff valve is closed, or fuel line or fuel tank cap vent is clogged.
2. Carburetor is overchoked.
3. Carburetor is improperly adjusted or needs service.
Use carburetor cleaner and lint free cloths or paper towels to remove all built up brown or green gunk, varnish, and other contamination from the metallic parts. Pay particular attention to the machined passages and metering holes.
WARNING: Carburetor cleaner is both flammable and the fumes are toxic. Do all cleaning away from open flames and outdoors if possible. Wear eye protection. The stuff will also eat plastics including some plastic eyeglass lenses.
Take care where non-metallic parts are still in place as extended contact with harsh solvents may degrade their properties (inlet seat and primer bulb, if present). Low pressure compressed air may be used to blow out passages but only use this on the fuel line from inside the carburetor body - else you may end up with the inlet seat clear across the driveway never to be found again.
DO NOT use wires or metal instruments to clear any of the passages as their size is critical.
