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.

Hi! Look for the spark plug,take it out and replace it with a new one,and then try to start it up.Also check if you have fuel and oil mixture right.
It is the most common failure in such hardware.Good luck!

What is the gas oil ratio of the ryobi leaf blower


Most Ryobi products made in the past 5 years use a 50:1 fuel mix. Check the fuel cap to see if it is listed there. The older Ryobi product used a 32: 1 fuel mix ratio and it was usually listed on the sticker that shows you how to work the choke. If in doubt, go with the 32:1 ratio. The only thing it will cause is premature fouling of the spark plug. Too little oil in the mix will cause premature engine wear.

50:1 is 2.6 ounces of 2 cycle mix to each gallon (U.S.) of gasoline.
32:1 is 4.0 ounces of 2 cycle mix per gallon.

I recommend to use a 2 cycle mix that is specifically designed for lawn equipment and contains fuel stabilizer. The ones with stabilizer will usually be .5 ounces larger.

Good luck!

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

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.
