Question about Ryobi Backpack Blower 25.4cc
CAN GET IT TO RUN GREAT IF I TAKE THE AIR FILTER OFF AND PUT MY FINGER HALF WAY ON THE AIR INTAKE HOLE
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.

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!

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
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:
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

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.
