Information about video:
When the leaf blower wouldn't turn on anymore, I took it apart and checked the fuel, then the ignition. After diagnosing those two problems, the only thing left to check was the engine block, so I got to the block and found the problem. A worn piston and piston ring, isn't that something?
The compression was terrible. So I purchased a new engine block today, on 4/14/17 from Troy Bilt, so I cant wait for it to get here. Its only a matter of time until I have a brand new Troy Bilt leaf blower working again! Thanks for watching me go through this wonderful experience and finding out the problem to my leaf blower.

Very common problem with the tb430

@fleadoggreen9062 3 месяца назад

I barely used the thing I always use more oil than needed

@afreakingcat 4 месяца назад

Jesus I did the same thing... Ignition coil, momentary switch, spark plug, fuel lines, fuel filter... Nothing. And I did open it up and see the piston rubbing I thought maybe it was because it was dry with no fuel/oil to lubricate it.

@GreenThumbEngines 3 месяца назад

Your probably right. But mine did the same. I opened it up and the piston rubbed against the cylinder block. I think that’s how these blowers usually fail. I saw another video of a person talking about the same thing and that’s how I learned how to take it apart. So I just bought a new motor for 40 bucks and it cranked right up. Brand new motor for 40 bucks lol

@afreakingcat 3 месяца назад

@@GreenThumbEngines I did the same thanks to your video. I got the short block for 50 dollars. Started right up after. Now I need to find a new project 😂

@bassmatters1012 5 лет назад

I have the same model and ran it twice with correct mix and it got to where it wouldn't start. So I cleaned the carbs out and spark plug and it would only run choked. So I decided to pull the piston out like you did because I could see thick carbon on top of the cylinder and mine look exactly like yours. I'm junking it and buying a stihl! I've had my still weed eater for three years now and it always starts on the second pull. Cool trick with the rope I don't have a impact wrench either. Thanks.

@ricksouthernrock2639 Год назад

Same for mine, it starting acting up after using 3 or 4 times and I purchased it brand new. It's a piece of junk.

@abuehler81 3 года назад

Good tutorial. Next time just open muffler and you can see the damage and save yourself some time.

@GreenThumbEngines 2 года назад

Good call! I just enjoy getting my hands a little greasy :)

@craigkerr9281 4 года назад

I want to thank you for taking your time to show us the explosion part of the engine taking apart piece by piece. this is probably why my way blower runs for two or three minutes at full speed tests are slowing down rapidly to install.

@natesmith5477 5 лет назад

after a11/2 my troybuilt weed eater same thing. worn piston I may replace if its worth it.

@DivendresGreetings 4 года назад

Thanks for the video. I'm having the exact same problem with exactly the same blower model. Did the replacement parts last longer since you put it on? I bought this thing for $30 and spent $20 on the carb and now I'm wondering whether it makes sense to spend more money on this stupid thing. TIA.

@GreenThumbEngines 4 года назад

Yep, I still have it till this day. Works fine. I don’t use it as much as I did since I have other blowers. But I still use it every now and then. As far as worth? It’s pretty cheap to me. The engine block is $40. I’m not sure how much the whole unit cost in stores. But if the engine fails all you need is $40 bucks and you got yourself a brand new engine unit again

@jaimebotello3512 3 года назад

@@GreenThumbEngines where can I purchase the new block do you have a number or website

@robstone5333 5 лет назад

Hello, before you waste your time and money for parts, there's an easy and quick way to check for serious engine damage. As over 90% of scoring will be on the exhaust side of the piston, just pull the muffler and take a look using a good flashlight. Any scoring/damage is easily visible. This knowledge will allow you to make an informed decision on your next course of action. Thanks for the vid.

@GreenThumbEngines 5 лет назад

Either way. I really enjoy disassembling a small motor to find out the cause of the problem. I don’t think it wastes my time at all. It’s definitely worth every second to me going through the entire piece and cleaning everything to make it last longer

@robstone5333 5 лет назад

Sure. I got you. Thought you were doing this for part time income or something. I feel the same way; it’s enjoyable and almost relaxing for me.

@craigkerr9281 4 года назад

WOW this observation of looking into the exhaust Port really helped I can see scoring on the Piston but I don't understand I've always used the correct amount of fuel and still got a burnt piston or piston rings or scoring in the cylinder whatever you want to call it. I have the same exact blower tb430. I do not have much time on this engine. But really pisses me off that Troy-Bilt thinks they are such good equipment and it feels so EZ cheap equipment cheap parts never again Troy-Bilt From now on it's still all the way. Unless of course Troy-Bilt

@robstone5333 4 года назад

Craig Kerr Unfortunately, even with the correct fuel/oil mix, this can still happen. Even a minor air leak will alter the fuel/air mix. This will cause a lean running condition, engine will run hot, scoring and other fatal conditions result. TB used to mfg good products. Nowadays, IMO, TB sucks. Just more crap from MTD.

@charlless5429 2 года назад

Grats! I learned a lot working on lawn equipment like that blower you disassembled, but generally, mine were much more dirty. Yours looked close to new. So, running too lean??"

@GreenThumbEngines 2 года назад

possibly. could be the reason why the piston rubbed against the cylinder wall and damaged the engine. I had to buy a new motor for $40. Works great till this day and I made this video a long time ago.

@tonygram5414 Год назад

Good job, running these units lean will cause that. I know the mix is what it is, sometimes running a little extra oil doesn’t hurt, it may smoke some, I mean just a little extra but it saves the lower end. Excellent work!

@GreenThumbEngines 2 месяца назад

It’s the best comment I ever read!

@ColoradoCarrolls 2 года назад

Bought one of these . Didn't start because of the fuel/Air Mixture at 6,000 ft. runs like shit now.

@GreenThumbEngines 2 года назад

interesting.. not sure what you mean sayin, "fuel/air Mixture at 6,000 ft. Are you referring to the altitude of your location, or something else. You got me wondering what you're talking about haha :)

@ColoradoCarrolls 2 года назад

@@GreenThumbEngines I bought this Blower brand new in 2012 and I still have issues starting it. Then when I do get it running it takes another ten minutes! to warm up. I can't run it wide open till about the 30 minute mark. I have know Idea what causes that other then I live at 6000+ ft here in Colorado. any suggestion I would deeply appreciate

@rileysindt6689 4 года назад

It appears that your blower would be 2 or 3 years old at the most. They switched to that new style of blower in 2017.

@GreenThumbEngines 3 года назад

Yeah it’s pretty old. But it still works. $40 for a new engine block, not bad

@hvacjay4037 3 года назад

Awesome video man. thank you very much for posting this. I have the same leaf blower with the same problem and after I watched your video I tore down the engine and had the exact same issue with the Piston scored up.

@GreenThumbEngines 3 года назад

Very nice! Did you order another engine block from Troy bilt? It’s only $40 bucks shipped and you’ll have a brand new blower

@anru9492 4 года назад

Great video. I have a question. So thi piston is scratch so we replace it with new on and new rings. Do we have to do anything to the block? I need to replace mine thats why I ask. If the block is scratch also do we sand it, replace it or just changing the piston will do?

@GreenThumbEngines 4 года назад

That is a good question. Well my piston was destroyed along with the rings. And inside the cylinder block had scratches in it too. In order for it to work properly, everything has to fit just right and all walls and surfaces must be flat and smooth (no cuts in metal). What I did was purchase the entire engine block from the Troy bilt website and it came with everything including screws. The total cost when I purchased it was $40. So basically $40 and you got yourself a brand new engine. Just assemble and screw everything onto the engine and you are good to go. So overall, to answer your question, just buy a whole new Engine Block, will only cost you $40 :)

@anru9492 4 года назад

Thanks for the reply and sharring. Who would think they would scratch up like that like if sand got in. But Yeah sounds good just install a new one. Mine is a 753-08712 found it for $42 on the site you gave me. Just brought it. Thanks

@GreenThumbEngines 4 года назад

Fantastic. Glad you put the part number for others to see as well Incase more have problems too. Pleasure chatting with you.

@scottmilner2915 6 лет назад

I have the same blower and I've got good fire and it feels like I have good compression but not sure if it's enough cause I can't get it to crank is this what was going on with your blower

@GreenThumbEngines 6 лет назад

lol yeah, i know why maybe its doing that. Um, grab your blower and look at the Black Air Filter Cover. it should have like a red switch on there, flip the switch to the left, then prime the gas a few times and try starting it. it should start in like 1-3 pulls with the red switch to the left. once its on, flip the switch back to the right instantly. that switch is called the choke. its meant for starting it up when you havent started it in a while or also known as (cold start). let me know how it goes.

@clarkkd801 5 лет назад

What was the compression on the blower you took apart, please ?

@jonienglish3231 6 лет назад

just picked up a weedeater vs2000bv 25cc 2 stroke no start , piston ring seized to piston thats why no compression

@GreenThumbEngines 6 лет назад

damn it seized? did you take the head off to see it? should try scrapping the piston head clean with a wire brush and pouring a little bit of oil between the piston and bore, and then clean the spark plug tip and try starting it. it might fire up for sure. if the engine cylinder wall is bad, then it might shut off after you start it but it will start for sure if you clean the inside.

@jonienglish3231 6 лет назад

took the head off , ring seized to piston , tried to soak piston with CLR, penetrating fluid , loosed up slightly then ring broke . there was a new plug from previous owner , lots of spark , i even rebuild the carb and sprayed Brake kleens to try and start it . got the new ring and installed yesterday , lots of compression now , the piston was smooth no scoring , even cylinder walls no scoring

@GreenThumbEngines 6 лет назад

aw damn. that sounds good to hear wow. sounds like you got yourself a long lasting machine now :) i like hearing shit like that. keep up the good work man.

@jonienglish3231 6 лет назад

i am surprised by the power and vac capability , i have a 20v dewalt blower nice and simple but the gas 2 stroke blows the 20v dewalt away , only thing is after 1/2 of use hands get tired from the vibration . get the gel anti-fatigue gloves next time also running on 40:1 Trufuel this stuff is amazing

@jonienglish3231 6 лет назад

Hi just posted a rebuilt craftsman snow blower seized engine rebuild

@davidwargnier7337 6 лет назад

my murry /mtd same exact problem 2 seasons. threw it in the junk. looking now at new, all the low cost stihl, echo, husqvarna ones only have 1 piston ring. can't see that lasting long. only mtd built has 2 rings on the piston and still junk.

@GreenThumbEngines 6 лет назад

having one ring or two shouldnt make a difference if its junk or not. if the motor is operating like its supposed to, then it should be good. rings just provide a good seal for oil not to leak. if the motor blown, it must of been a gas/oil mixture problem like mine was. must of been running too lean or too rich. in my case in this video, i was running too lean (not enough oil) is why my piston was scored and scratched just like the head was.

@reidairsofter 5 лет назад

GreenThumbEnginges the head cannot get scratched by the piston unless you have serious issues. You mean the cylinder wall

@wampaswomps3975 4 года назад

I got the same TB430. And same problem i believe. I've done spark plug and verified spark, air filter, cleaned all carb jets, verified that im getting fuel, the piston and rings is all that's left! 👍 UPDATE: Took it apart and no scoring anywhere BUT had low compression (20 psi) so I replaced the rings anyway and NOW can’t get the piston back in the cylinder it’s too tight. And no way to compress rings except with fingers! Very frustrating. This is why I’m not a mechanic by profession lol

@GreenThumbEngines 3 года назад

Awwww daaammnn. I like doing that part lol what you do is get a bottle of car oil and touch the oil with your finger a little bit. Then rub it around the top of the piston where the ring is. Then you compress the ring with your fingers like you said while trying to slide the head back on... with the oil, it will slide on easier because of lubrication from the oil. I hope that helps

@anmiles18 7 лет назад

Nice video! Mine starts ok right now, but stalls after ten minutes or so. I cleaned the air filter. I'm hoping it just that. Simple motor but I don't think I can do what you did.

@jonienglish3231 6 лет назад

Ethanol Fuel Contamination , possible needs carb

@anmiles18 6 лет назад

Yea I hit it with some carb cleaner, it seems a lot better now. It's hard to find non ethanol gas.

@GreenThumbEngines 6 лет назад

sure you can andrew. just a little analyzing and remembering where the parts go after you take them off :) I bet you can do it no problem. thanks for commenting and enjoy the holidays!!!

@GreenThumbEngines 6 лет назад

your carburetor just might need cleaning if it stalls. just as simple as taking it off and spraying all the ports of the carburetor with carburetor fluid

looks like lack of oil

@GreenThumbEngines 6 лет назад

thats exactly right. that was one of my first machine I ever mixed oil for. So I had to learn the hard way. but its working now. I bought a new short block for it for $40 bucks and it works fantastic. 40 bucks and now I have a brand new leaf blower haha go figure :) well thanks for commenting and enjoy the holidays!!
