My ryobi bp42 starts and runs good but when I stop for a few minutes it want start . I come back the next time it will start and run it I keep gas in it and don't stop it it jus keeps running fine

Do you prime the engine when you want to restart it? If so you may be adding too much fuel and flooding it out. Try restarting it without adding more fuel. If you are not priming the engine, then add a pump or two and see if that helps. If it does not start, pull the plug to see if it is wet. If it is, then there is too much gas.

Leaf blower problems

Greetings & salutations Charles Klink,

You need to correct your 2 cycle oil to fuel ratio...

The engine needs the appropriate oil mix to keep the engine from seizing...

It is REALLY ******* the engine not to
be completely meticulous about your oil/fuel mix.

Hope this helps

I have a Stark backpack blower. Ran for an hour perfect then started bogging down. I shut it off. Now the pull cord won't pull more than a couple inches. How come?

If the engine is a 2 stroke the fuel must be mixed with 2 stroke oil at the ratio recommend by the engine manufacturer. If the ratio of fuel to oil isn't followed the engine will not have enough lubrication and will seize

Backpack gas blower

Monching, You will have to hope there is not too much damage done already from running straight Gas. Empty all straight gas from blowers tank and refill with proper minimum 50:1 gas oil mix. Start blower and run on 1/2 throttle for a few minutes to be sure its going to be OK. If seized, you will have to try and unseize and if lucky it may run if not too much damage internally. You should run a heavier oil to gas mix 32 or 40:1 in an engine that's been seized. Check the attached links,instruction and guides, Good luck

I need to know how many ounces to make per gallon with craftsman 2 cycle motor oil for ryobi 42 cc backpack leaf blower

the mix is 50:1 so the weight to volume will not matter
if you have a 1 gallon tin the amount of oil will be 1/50 of the gallon
1 gallon =128 oz so a ratio of 50: 1 would be 1 gallon of fuel to 2.6 oz of oil or 1/50 of the gallon calculate the oil required by dividing 128 by the recommended ratio figure (128 divided by 20 or 30 or 40 or 50 to get the oz amount of oil)
the thing is that the mix doesn't have to be exact as long as it is not tool short on the oil
so a mix ratio of between 30:1 to 50:1 will run in 2 stroke engines but a mix of 60:1 will cause problems
A good mix is when you can see a faint oil smoke when operating
too muck smoke and there is too much oil and no smoke too little oil
the major factor is--- do not use e-mix fuels

How do I fix a ryobi bp42 that will not start

It's a 2 stroke & it's relatively new. as long as you didn't score the piston by neglecting to add oil to the fuel mixture, the most likely problem is fuel issues. It only takes a month or 2 to have ethanol fuel absorb enough moisture to ruin the fuel mix. Return all carb settings to original settings. Empty your tank, get rid of your fuel, remix with NON-ETHANOL FUEL MIXED WITH A PREMIUM SYNTHETIC 2-STROKE OIL, such as echo or husquvarna. Purge all the fuel from your lines and primer. Remove the spark plug & pull the cord a few times to dry out the cylinder, run a flame under the spark plug to dry it out. Add 3 drops of fuel mix to the cylinder then replace the plug. Put it on full choke & pull 1 time. Then on 1/2 choke pull to start in 1 or 2 pulls. Still won't start; replace plug & air filter. Let it warm up for 5-10 seconds then turn choke off.

Ryobi BP42 leaf blower will start but will not rev up when I push the trigger - how can I fix this?

Its a lean condition, not getting enough fuel. Check fuel filter and fuel lines. be sure you have fresh fuel. and the carb needs to be adjusted or rebuilt.

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 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.

Without more information, the best guess is that the piston is probably seized in the cylinder, this will not fix itself by adding oil now. It likely needs a new piston and/or rings and/or cylinder or shortblock assembly. You can google your model number for sources of repair parts. Depends what you find when you disassemble it, if you can get the piston out you may be lucky to get by with a new set of rings and honing the cylinder.
But it will be a batch of work for a $200 blower. May be worth it if you can do it yourself and the parts arent too much. Certainly a shop couldn't do it for less than the replacement price of the whole blower.

Hello:

Remove the Muffler and Look into the Exhaust Port.
If the Piston has Scratches or Gouges, then the Engine is Trashed and will have to be Replaced.

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.
