SOURCE: Ryobi RY08576 25.4cc was started without mixed fuel

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: i just picked up a used ryobi rgbv3100 mulcher

test for spark.
while spark plug is out - put finger over hole see how much compression there is.

If good spark - look for holes in fuel line.

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

Ounces per gallon 31 cc engine


If this is a 2-cycle engine, Ryboi are 50:1 check age of gas. Cannot be more than 30 days old. Make sure to use fresh gas w/synthetic 2-cycle oil @ 50:1 ratio (1 gal.) Gas to 2.5 oz. Oil). Do not use old or stale oil/gas mixture. Always use the proper oil/gas mix. If you do not, your engine will suffer rapid, permanent damage.

Gas and oil mixed in 4 cycle backpack leaf blower


If it is a 4 cycle blower, you do not mix oil with the fuel....It takes straight Gas. there is an oil cap to put engine oil in crankcase, this only usually takes 2,3,4 oz. of oil. Sounds like your Spark Plug probably fouled out from having oil mixed in your gas. I would recomend changing your Spark Plug and put some Fresh GAS only in the blower, dump the old stuff out !!! You should be on your way Blowing in No Time !

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!
