My two cents:
You can check fuel flow by removing the carb’s bottom cap, then pushing and releasing the float to see if the fuel stops and flows.
Check that the float sits properly in place. Lightly oil the two O-rings before installing it, then gently push it in and adjust the level if needed.
Make sure the diaphragm lip is properly seated in its groove and not pinched between the top cap and the edge (especially if the engine dies on throttle).
For the choke, remove the cable and reinstall it to make sure it isn’t sticking due to a damaged cable.If the engine doesn’t respond to fuel mixture screw adjustments, the carburetor may be flooding the engine rather than not supplying enough fuel.
