If the engine is sticky ie harder to pull it might have to be pulled apart new piston and honing of cylinder. not difficult just a pain. If it doesn't seem any harder to pull, Drain all of the unmixed fuel. Put a few drops of 2cylinder oil in the spark plug hole and pull the starter a few times with the plug out of it. Put a few more drops in repeat. Replace the plug (new plug) Put in mixed fuel prime the system cross your fingers and it should start up for you.

SOURCE: how do you change the fuel filter on a ryobi

Disconnect the fuel Line from the carburetor and, using needle nose pliers, grab the fuel line in the tank just behind the filter and pull the line and filter out of the tank. BE CAREFUL YOU DO NOT PULL THE LINE ALL THE WAY OUT OF THE THE TANK!! Pull the filter off and replace with the new one and put the new filter back in the tank, then reconnect the other end of the fuel line to the carburetor. Hope this helps!

SOURCE: ryobi backpack leaf blower about three years hard to start

Basics to check:
1) Spark plug - brown or dark brown - OK
a) is it carbon or fuel fouled
b) is there spark

2) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated
3) Check cylinder compression


Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

SOURCE: Ryobi backpack blower will run all day with choke

Thats a lean condition. Check fuel lines and fuel filter. If the fuel ilnes are discolored or stiff or really super mushy, If the fuel filter has become detatched from the fuel line then the fuel lines need to be replaced.
If the carb can be adjusted you can try to adjust but its likely that the carb should be rebuilt with new diaghrams and gaskets.
Adjust by turning the low speed screw out ( counterclockwise) 1/2 a turn. The low speed screw is always the one closest to the motor and usually marked on the carb body with an 'L'. When you richen a motor up the idle will drop so you will probably have to turn the idle screw in 1/2 a turn. 1 and 1/2 turns out from light bottom is standard starting point ( 2 turns for poulan products). If you get more than 3 and 1/2 turns out on the low speed screw or if turning the screw has little or no effect then the carb should be rebuilt.

Ryobi 9600 backpack blower. Starts great. Set to run, continues running. Upon attempt to use throttle, engine dies. Acts like choking out but removed carb cover an choke is no closing.


this sounds strangely like the high speed jet/pathway in the carb is clogged up with something ,

the best way to fix it is dissasmbly and cleaning of carb in solvent , but ive also had some limited sucess in past of using car fuel cleaner (says on bottle "cleans as you drive") too

Ran last year, won't start this year. Changed fuel and replaced spark plug. Checked spark and attempted to start with battery and tried with pull cord but no start. pulled plug and it had fuel on it so...


It might have tipped over on its side. Look at the air filter, if you see oil or gas on the filter then you might have to remove and clean the carburetor. I would start by cleaning/replacing the air filter and trying it again. If its getting fuel and the spark plug works then the only other side of the fire triangle is air.

Ryobi b/p blower ry 08570 stalls out when givin the gas why and how can i correct this problem? do i need to throw it to the curb and buy an echo?


I would check your fuel filter and make sure you have all fresh gas in tank, then I would check to see if it will run with choke on , then I would check exhaust port and muffler screen for being plugged, then I would dissasemble and clean carb and check diaphrams and pump for being stretched and also clean out inlet screen and needle&seat . If all else fails I guess I would do the alternative either an echo or redmax or dalmar ! dalmar makes a great 4 cycle takes reg gas I have one it is great!!

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.

Remove the muffler and you should find that it will run at full speed. The muffler is clogged with carbon. You will have to replace the muffler since it is sealed. If you want the muffler cleaned you can contact southern supply company at 205-833-2525 or email them at

southern.supply@mindspring.com and I feel sure Jason or

someone there can help you.

Backpack only runs low RPM, especially when cold.


Your carbeurator is gummed up. Remove the old fuel and make up a new fuel mix with new gas from the gas station. Then get a can of carbeurator cleaner spray. Three short squirts in the air intake and let it run. Three more squirts every minute or so until you dissolve the partial blockage that is causing your problem.

I pull the cord but it will not start, i have a Ryobi Backpack Bl


Ok that's half the battle. Probably the easiest thing to do is to clean the carb. So I would get some carb cleaner and using the little tube that comes with it spray into the high and low ports on the carb. Then spray in the outlet side of the carb.
Ps. Remove the little black and white caps and turn the screws on each while counting the number of turns to close (this way when you put the screws back in then all you have to do is count the turns to put them back at the factory settings). Now remove the screws and gently put the tube in each port and spray.
Also you may as well clean the filter with soap and water and let it dry. Once the filter dries take some fresh oil and drop a couple of drops on the filter and make sure it's has a small amount of oil in it.
Let me know how things go! Good luck!
