Ryobi Leaf Blower Repair - Will Not Start, No Spark BP42

[@hemikid52]

Great job James. Learned more in general about engines, carbs, recoil, and given a little patience most machines would run right and be usable instead of throwing them away... really liked the explanation about the leaning out the carb and overheating the engine. You have great patience. Thank you!

[@jcondon1]

Glad I could help. Thanks for the comment.

[@Silent-Lucidity]

As soon as you said it belonged to a mechanic... I knew it wasn't cared for! 😊 Who wants to wrench all day and then come home and wrench? 😊 I have that machine and it runs like a champ.

[@GetOffMyLawn1970]

Very informative and educational! Best video I’ve come across on the Ryobi BP42 so far! Thank you!

[@waynebrundidge206]

At the end someone was having some fun. Thanks for the video and the info.

[@bertgrau3934]

That thing sounds good. I worked on a Harbor Freight Predator engine. The carburetor and coil was about $30 . You got a good deal. Comparing 2 stroke to a 4 stroke can make a big difference. Great job Sir

I love your bonding with your boy. Good dad!

[@miguelaldana4836]

Yes you can fixed u are very smart small engine mechanic guy, I love watching you videos

[@sidneyperry7623]

Picked the same blower in my travels on a "FREE" pile beside the road. Found the primer bulb fuel lines backwards, clue, air bubbles from filter in the tank. But still have a bone dry spark plug, so gas isn't making it through the carb to the piston. So I've ordered a new carb, so the fight goes on. Anyway thanks for the video.

[@doughess1001]

Great video. Perfect script on for new comer to check out BP42 issues. While I am experienced at repairs could not figure how to access and check spark plug. Usually a no brainer many engines. Thanks again for all the helpful info.

[@hanselmanryanjames]

You got the comedic timing down. "Don't want to take this off because there's going to be springs flying everywhere". Cut to springs flying everywhere. Good stuff.

You're amazing all the information u know and filming is great

[@YooTooobJeff]

Use the start procedure listed in the air filter cover exactly... These can be picky machines but run well if you play with them correctly

[@Roy_Tellason]

My lady was using a broom to clear snow off the deck that''s outside our back door. I suggested that a blower might be useful in this context, and she liked the idea, so I bought her one. It's a Ryobi too, but not a backpack style, and it runs off a battery, so I won't have any carb hassles to deal with... :-)

[@YooTooobJeff]

High speed is adjusted not to max speed but just a bit past sheer the speed just slightly drops of, so the motor runs very slightly rich which is a cooler temperature that extends the engine life

[@MrTonyPiscatelle]

Nice fix James, guess it has plenty of power it set little man back on his heels for a moment ...lol

[@mikesartorii234]

I've have 2 of these and maybe I'm unlucky but BOTH had to be sent in for repair the 1st frikkin season I had them! When they did run they worked just fine but both are finicky to start sometimes. In fact I have one that won't start at all so I bought an Echo 580 T because I'm tired of screwing with these pieces of crap! Thanks for the vid though, I might mess with the unstartable one if not I'll just keep it for parts to keep the other one running.

[@samuelfellows6923]

Interesting - the exhaust on that discharges into the fan shroud, the small rusted pipe under the muffler that goes into the plastic, so you won’t have any fumes behind you, that’s being blown out of the nozzle

[@johnclarke6647]

You have to have at least a 7# seal on the gas tank. I pressure test all tanks with my Mighty Vac. The fuel line always plugs into the metering side and the return line always go into the outlet line that blows air when you depress the primer bulb.

[@fish2day918]

i also picked one of these up and thought it had a velvet mold on it , didn't want to touch it.

[@Jim-ie6uf]

My old neighbor was an airplane engine mechanic. He couldn’t figure out two cycle engines to save his life. For some odd ass reason, the small line is the inlet line, the big one is the return. Things that make you go hmmmm. The proper term is a purge valve. The short side is the suction side, it pulls fuel thru the carb, not pushing it into the carb.

[@jackdup9454]

Nice video, thank you

[@JMassengill]

I once was part owner of a small engine repair service. I understand how two stroke engines work but because they were such PITA when it came to the carb, we refused to work on them as they sent us so much return work. They were not worth the time and effort it took to keep them running as most people would go buy a new machine before they would spend the money needed for repair.

[@jcondon1]

I agree. They are a lot of work and not worth much running. A lot of times it does not make sense to pay someone to fix them.

[@mikesartorii234]

Same here! My local place refuses to work on these junkers! So I bought an Echo.

[@joewilmetti3296]

Old post that I just discovered. Have a BP42 that needed a tuneup & maintenance. I’d certainly like to find the kit with all the parts that you found. Is it possible that you still have that info?

[@gussferretti9665]

I replace the coil every year they tend to go bad quick on this model, the flywheel has no fins to keep it cool so when you want to start this machine hot it won't restart.

[@jamesbubnick]

I’ve never owned a ryobi gas power equipment but I’ve owened at least a dozen echo 2-cycles and never replaced an ignition coil in over 20 years. You might want to check out echo next time.

[@inoahmann7542]

@@jamesbubnick yeah, echo is fantastic. My backpack blower starts 1st pull ever time on half choke. Absolutely the best piece of equipment I have. I also have an echo srm200be made in 1984. It also runs amazingly well.

[@jamesbubnick]

@@inoahmann7542 I've only had one piece of echo ever fail and it was 15+ years old and heavily used. The casting where the muffler bolt attached cracked and you couldn't attach the muffler anymore. It still worked but was loud. I sold it as is to a guy who didn't care about the noise....At my home I pretty much run the synthetic echo fuel since I'm only using a few gas tanks a year between everything and I don't have any starting/idling/storage issues. I figured 20-40 bucks a year in synthetic fuel is worth it. I also bought the Echo 58V line to try out and the chainsaw is awesome!!!

[@inoahmann7542]

@@jamesbubnick nice, I really like grass gador twisted trimmer line. It cuts really well. I use amsoil saber 100 to 1 fuel for low stress tools like weed eaters and 50 to 1 for chainsaws, leafbloweres, and any other equipment that pretty much runs at wide open throttle all the time. I really should use non-ethenol gas but I don't. I do replace about 1 carburetor every year but to me that is better than driving 2 hours to the nearest place that sells ethanol free.

[@mikesbarn1858]

Just FYI. Various mechanic disciplines don’t always cross over. Diesel doesn’t translate to gasoline. Car doesn’t translate to lawnmower or 2 stroke.

[@martinmoffitt4702]

Nice job thank you...I don't know if I missed it but how do you use a ohm meter to check to if a coil pack is bad?

Good show. Thanks for all the info. Does it ever warm up there?

[@jcondon1]

We get the extremes. A good cold winter and a hot summer.

[@nhanquach4388]

Help? My Ryobi backpack blower is still somewhat new, fuel/oil mix is fresh, used twice successfully in the last 3 weeks. However it ran for like 2 mins and then now it won’t start and given that it’s still new I ruled out the fuel and air and decided to troubleshoot the ignition, I didn’t see a visible spark on the removed plug, So I took the risk and touch the spark plug on the spark should be and the shock was very weak like 1/4 of what I could get a stronger static spark at the playground on the McDonald’s play slide. Could that be a bad ignition coil too?

[@jcondon1]

Sounds like it could be a spark issue if you are not seeing it jump on the plug. First try another spark plug and chec the gap. I have a video troubleshooting run issues kzbin.info/www/bejne/jpKQkp6HZb2fZqs. About 6 minutes in, I discuss troubleshooting spark. Could still be fuel, potentially the fuel filter fell off in the tank. Also easy to try a little starting fluid to see if you get any ignition. The order to check things in from most common problem to least is 1) fuel, 2) spark, 3) timing and 4) compression.

[@mgoody8782]

Most people use a spark gap tool , lol

[@Rennsport-Media]

I have the same issue…. No spark. I have changed the ignition coil, the on/off switch, and the spark plug (all OEM) and nothing. Very frustrating…. Can’t figure it out.

[@jcondon1]

Make sure the coil is not upside down, check that the flywheel magnet is still magnetic and remove the kill wire from the coil and check for spark again.

[@HondroGonzalez-zv5zv]

Awesome

[@collingreenway2966]

I have a blower I picked up for free a while ago with some things wrong but when looking through videos and parts I can not find a single one with the carburetor that’s on mine and my airbox is where my choke/run lever is. It looks like the second one you put down in the video when you were talking about seeing if any other ones you had would fit. Please let me know if you have any ideas

[@jcondon1]

I think that came from this? kzbin.info/www/bejne/g4XHioqJrpijaaM

[@jimdavidson5208]

THAT one looks like a lawn crew used it all up. Sun faded and recoil destroyed.

[@MHOLDINGS]

What kit did you buy? Do you think my problem is the coil if it runs perfect when I grab it out of the garage but after I go to add gas (as it turns off) I have to wait almost a hour before it will turn on again? Guessing it’s heat; have already replaced the plug ... thanks for the helpful video !

[@mikesartorii234]

Same, if you use these for awhile, stop them for whatever reason, good luck re-starting them!

[@MHOLDINGS]

@@mikesartorii234 yes I replaced carb and everything ; that’s not the problem. Also the coil and plug ; I think the issue is with the compression/piston/seal and once it heats up it doesn’t allow correct compression to actually spark and run again. Only thing I haven’t changed is the piston and I’m not going to lol

[@6THSAK27]

Need coil for mine. Parts look up to buy parts?

[@jcondon1]

I got this kit from a seller on eBay. The kit I got is no longer available, but if you search for "Ryobi bp42 ignition coil" you should find it.

[@Stubby0266]

Mine does not have compression. Loses rpm once warmed up acting like leaning out. Added choke and wants to die acting not leaning out. Can hand turn the crank very easily. Thinking of the next size up of piston rings.

[@jcondon1]

I am not a 2-cycle expert by any means, but if you pull then engine over after it is hot and the compression feels weak as compared when cold them most likely a top end issue. Potentially the reed valve, crank seal or maybe the head gasket or head bolts no torqued well.

[@6THSAK27]

Where did you buy the kit?

[@50oaklane]

What tool did you use to get the chassis and the engine cover off?

[@alext8828]

I don't think the hand-held blowers have throttles. They just run full-bore all the time. Is that why the bore is smaller? Not sure.

[@johnclarke6647]

Ryobi back pack - my guess is a Mexican owned it and left it on his trailer all the time and rain and snow got into it. Unlike us, they never store their tools away, properly. Growling bearings and bad seals are also a possibility, as is water in the carb. You can also bet everything on it is basically connected wrong. They can get things running with duct tape and vice grips but they usually do not run for very long.

[@hanselmanryanjames]

Right because only Mexicans abuse their tools apparently. Wow, just, wow.

[@Fredjoe5]

Hope he was wearing ear protectors using that.

[@richmoulder4901]

Excellent video James. Thanks. I have this same machine, fortunately in much better condition. I am having trouble with it and I have nowhere near your skill with small engines. Once my machine warms up it won't run full throttle. When I try to give it fuel it stalls out. Where should I start troubleshooting? Thanks.

[@jcondon1]

Usually that is a carburetor issue. Either the jets need to be adjusted or it may not be getting enough fuel. The carburetors on leaf blowers have a diaphragm pump what uses engine vacuum pressure to pump fuel. It is common for that part to wear out and stiffen up or tear. That diaphragm can be replaced. Often it is not much more to buy a Chinese clone carburetor, but sticking with OEM is usually better. Does it get better or worse if you give it a little choke?

[@richmoulder4901]

Thanks again James. I have to admit I have not been good about keeping fuel fresh. I am on a mission to correct this going forward. If the carby is fouled, it's my fault. I think replacing it is maybe a good idea. Do you know where I can buy the OEM part? Thanks, Rich @@jcondon1

[@jcondon1]

Rich Moulder eReplacementParts, Jacks Small Engine and PartTree are good places for OEM. OEM will cost around $70. I went with a knockoff for $15. Either way you will need a Pac-Man tool to adjust the jets. A new card is set to a good starting point (usually), but it most likely will not run right unless it is adjusted to your engine. Make sure you get the model number on your blower when matching up the part. There are several versions of this blower all called BP42.

[@richmoulder4901]

Hi James. I got back to it today. Fresh fuel, even changed the spark plug that was about 5 years old. Still having the same issue. To answer your question it gets better when I give it some choke. Do you recommend trying to adjust the carb or just replace it at this point? By the way I bought a pac man tool. If adjusting the carb is worth the effort, it appears I need to detach it from the body because the fuel tank is in the way. Any concerns about it having loose while I run it and with play with the adjustments? Thanks again, Rich @@jcondon1

[@jcondon1]

Rich Moulder if you have the tool try adjusting. The carb must be tight on the machine before running and adjusting. Choking it gives it more fuel (but less air also not as much power) so it is a carb issue if choking fixes it. You might be able to remove the bolts on the bottom holding the engine to the backpack. The fuel tank is attached to the backpack so you might be able to slide it away enough to run (fuel line may not be long enough). Before adjusting turn each jet in counting the number of turns so you know where it was before adjusting. Then turn back to where they were and start it. You will need to turn out to allow more fuel in. Either way you will have to adjust your new carb so should try adjusting the old first. There are a lot of good videos that detail how to adjust two cycle engine carburetors. Would watch a few of those before trying. You do not want it running lean. Engine will overheat and not enough oil will make it in the engine potentially causing damage.

[@hussainsvt9853]

Good video. Can you post the web site where you got the parts kit.

[@tjgotone8647]

was wondering when you put the new coil in did you measure the ohms on the new one? I have 2 ryobi exact same blowers and both are giving me about 8k ohms kinda close to what you first measured. And yes no spark. Could they both be bad? i'm thinking tho maybe should be about 3k ohms. thanks

You have to instill in a kid that they need a plan to get anything done, properly.you just can’t walk in a path. That path must have some logic to it, based upon what you have to do. I taught my girls to cut two cuts around the perimeter and then, cut to the inside until everything is mowed. Otherwise the just cut in whatever pattern their little mind takes them and the job never gets done. You have to create within their nought process the concep of planning their assignments. I am a retired First Sergeant and First Sergeants don’t take a dump without a plan, so my commanders have told me.

Grate job can you tell me how the fuel line go I have the same problem have a good one

[@jcondon1]

Marcos Morales the fuel line that comes from the fuel tank that has the fuel filter on it goes to the bottom on the carburetor (side opposite the choke). The other line from the fuel tank goes to the long port on the purge bulb. Then connect the short port from the purge bulb to the top port on the carburetor. The idea is that the purge bulb pulls the fuel through the carb. Originally I connected it to push the fuel through which caused the carb to leak.

[@earlfahnestock1640]

It's smart to use Premium gasoline in small engines. Unlike an automobile it will probably cost only a few dollars a year more. If you bought the Ryobi BP42, return it and get a new one next season. They die after a year or so. Ryobi hillbillies will guide you through all the things that could be wrong. That process requires buying part they suggest, waiting for part, installing new part, calling Ryobi when that didn't fix the problem. I went through this 4 step/week long process-At least 5 times: Air filter(1 week), fuel filter(1 week), carb cleaned, carb replaced with a new one, new fuel and air lines installed, new plug. Over 12 hours and ~$100 into this and I give up. Ryobi sucks. Their hillbilly helpers are in the business of getting you to buy all these solutions!! Thet don't get paid to actually help you with your problem. If the Chinese blew leaves, they'd make a better leafblower. They don't-Ryobi BP42 is a planned obsolescence issue. This piece of crap is actually a terrific leaf blower when it works. Show me a homeowner who was able to fix their BP42 and I'll blow your leaves for a season. Also...when you're on the phone with them and they ask you for the serial number on your blower, you'll see that the serial number is sleazily hid by an impossible to read font size. DO NOT PULL THE STICKER OFF TO READ THE NUMBER!! It voided my warranty
