Craftsman weedeater will not start

The most probable problem is no fuel delivery to the engine.

1. Check/replace the fuel in-tank filter, you should be able to easily blow through it once removed. The primer bulb will sink down and not return quickly if the filter is bad. Fuel will not return to the tank via the return line if the fuel filter doesn't allow fuel to be pulled in.

2. If fuel is returning to the fuel tank when the primer is pushed then your problem is inside the carb.

3. To verify this put a small quantity of gas in the lid of a water bottle (half full). And pour it into the carb throat. Replace the air filter to prevent a backfire from shooting flames out. Try to start the weedwacker. If it runs and then dies the problem is inside the carb.

4. If you are really good at working on things with small parts you can clean out the carb and replace all of the gaskets to solve the problem. If this isn't for you then you should take it to a lawn shop and have them clean the carb and replace the gaskets.

NOTE: Replacing the gaskets is very important because the gaskets get stiff and the fuel pump action of one of the gaskets is reduced or stopped.

Hope this helps, Karl
