I just rebuilt my zama carburetor on my husqvarna saw and it still doesnt run right and i have blowed out my fuel filter and checked all lines and even tried to adjist the carburetor and it still cranks and i give it gas and it dies so what now

Turn the H screw to the left untill you can open the carb wide open. Sounds like the ajustment of the air mixture is off

Check there are no kinks in fuel line.
Make sure that the air filter isn't blocked.
Check the throttle cable is operating the throttle plate in the carburettor ok.
Ensure chain isn't too tight.
The carburettor should be a tight fit on the air inlet manifold.
It's possible that some of the jets could be blocked in the carburettor. You can try and clean these with compressed air but ensure you remove any seals gaskets, springs on the diaphragm pump , primer bulb etc as they can be damaged by the pressure.
You can also buy an aerosol can of starter fluid at your local autoparts store. This is sprayed into the carburettor to clear any partial blockages.
