The carb kit should be a 497578. Are you even getting any spark??
If the Engine will not start or is hard to start.
Possible causes:
1. Fuel tank is empty or shutoff valve is closed, or fuel line or fuel tank cap vent is clogged.
2. There is water in the fuel.
3. Carburetor is overchoked.
4. Carburetor is improperly adjusted or needs service.
5. Ignition system or its wiring is defective or ignition switch is off, or timing way off (e.g., broken flywheel key).
6. Deadman or other cutoff switch is open or defective.
7. Spark plug is fouled, improperly gapped, or damaged.
8. Engine compression is poor.
Think: FAST - Fuel, Air, Spark, Timing. Diagnosing a balky engine is not difficult but a step-by-step methodical procedure will make it a lot less traumatic. Despite all the warnings, serious problems rarely develop on their own. Most likely, there is a simple, easily remedied cause.
