My Ryobi leaf blower won't take a prime. If I invert the blower the primer bulb will fill and prime the carburator. The blower will start, but runs for about 20 seconds and then appears to be out

I don't mean to over simplify this, but are you using fresh gas? Gas string trimmers are extremely ticky when it comes to gas. They like it SUPER fresh. And while the gas and oil mixture should be right, it can be off a little bit and still run. Try draining all of the gas out, and then filling up with fresh mix. This is ALWAYS my first step with string trimmers, and it fixes the problem 75% of the time.
Hope this helps!!

Try running the machine with the gas cap loose. There could be pressure builiding up in the system due to the cap being too tight. There is no vent on these systems like an automobile. If the gas cap is overtightened this could be your problem as the cap is equipped with a gasket that allows the vapor to vent through the cap. Overtightening could be sealing off your vent

Follow the instructions exactly. If it won't start, take out the spark plug to see if it is wet, or dry. If it is too wet, the motor may be flooded. If it is completely dry, you have to figure out why it's not getting gas. I am assuming you are pressing the bulb the recommended number of times, and that there is gasoline in the bulb, providing some resistance to your pushes with your thumb.

If it is under 2 years old, I would take it to a warranty repair center. The carburetor have been giving some problems so they have needed to be replaced because they are sub standard quality.

The diaphragm in the carb may need to be replaced. Make sure all your fuel lines are fine. On these inexpensive blowers the fuel lines tend to get brittle and crack and fall apart.
