If it's new then it should still be under warranty, I would bring it back and ask for an exchange or have them find a place that does warranty work on it. Once you perform anything on it your self that could void out any warranty there is on the equipment. If there is no warranty then I may be able to help you further.

How long should a Ryobi 18v battery in a blower last?

Depends on the battery. It's age
Is the charger topping it up really full.
I bought a Ryobi grass trimmer and the book says it would work for twenty minutes. I used it for ten minutes and it was slowing down so I took it back to the store and bought a gasoline one. they said it was not for heavy use.
Maybe now they have changed but I was not satisfied with what I had to do.

Won stay running

Check carburetor & air filter. Clean off all dirt and clean air filter. check age of gas. Cannot be more than 30 days old. Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Before putting in fresh fuel, press the primer several times. A small amount of gas might show up in the fuel tank. Remove fuel. With carburetor cleaner, spray carburetor. Put in small amount of fresh fuel. Just enough to cover the fuel filter. Then press primer with fuel cap off, and watch to see if fuel is flowing smoothly. If not or if plastic primer bubble does not come back to original shape after pressing, then you have to take carburetor apart and clean or get new carburetor.

If the primer bulb is sticking down then, first try taking the gas cap off and pumping the primer. If this solved your problem, the duckbill valve built into the gas cap needs to be replaced, or you can replace the whole gas cap. If this didn't solve your problem, you have a clog somewhere else in the system or an internal problem with the carb. Try taking a pair of needle nose pliers and pulling both fuel lines out of the tank. Take the fuel "filter" off of the line and try pumping the primer. If it sticks down still, your problem is inside the carb. A rebuild kit would probably fix it if you are confident in tearing down and reassembling the carb, otherwise you can just replace it for about 30 dollars.

I have a hard time starting my Echo blower; the gas primer-bubble won't stay full. Can someone tell me a remedy?

It sounds like a typical obstruction in the fuel system. Make sure the fuel filter in the tank is attached to the fuel supply line and it is clean. After that, you can always try an adjustment first, but most of the time the screws have limiter caps or special headed screws to prevent "homeowner tampering". If the adjustments to do not help, you are left with installing a kit in the carburetor. Depending on your confidence in doing this task it is fairly easy to do. Word of advice, if your filter has come off the fuel line and if it has been this way for some time, you may still experience a problem once this is corrected. There is a screen filter located on the fuel pump side of the carburetor that will usually become clogged. Hope this helps.

Try running some fuel system cleaner through it. A good choice is Chem Tools Berryman B-12. There are some hardworking solvents in the product that could help you overcome a dirty carburetor. Initially use a good, strong dose. Maybe double what they recommend . (1 oz/gallon). If this doesn't work, the carb will probably need to be removed and inspected and cleaned.

Check the exhaust muffler, it might be blocked with carbon. Remove the muffler and start the engine, see if it runs. Soak the muffler in petrol overnight. Stephen.
