[@carlrussell89]

Thanks for this video! A neighbor was disposing of one of these blowers because it wouldn't start. I had no experience with small engines, but I thought that with the help of videos like this, I might be able to fix it. I picked it up, and after looking it over, I decided to replace the carburetor. Ordered a new carburetor with fuel lines, fuel filter, air filters, spare primer bulbs, and spark plug. Replaced everything with no problems, but still no joy. It would hit even with starter fluid. I pulled the muffler and looked at the ring and thought it looked okay. Put it aside for a while, then looked again and decided the ring might be stuck. I figured that I had nothing to lose at this point, so I disassembled the blower and engine and found the ring was indeed stuck. I broke it while trying to free it, so I cleaned the grove and piston while I waited for a replacement ring. I installed the new ring, reassembled the blower, and it started right up! 😂 Thanks again for posting this and giving me the chance to learn/do something new!

One thing to do is check continuity of the lead of the ignition module with a multi meter and move and pull the lead around while doing it and see if there is a break or loose connection somewhere. I have been caught out with that before where i checked for spark it was fine but when i plugged the lead back into spark plug i had nothing because of the way the lead was bent over to attach to the plug and i couldn't understand why it was not starting. It's not a common problem but i have seen it from time to time and worth taking a couple of seconds to check.

[@jamesturnure9735]

Genuinely a professional quality video; very articulate and thorough! I just went through the exact same gyrations with a Poulan BVM200VS blower that I trash picked. Went through the carb...renewed the fuel lines and freed the piston ring. Noted that it had a new spark plug (clue). Well, I get intermittent spark with the plug grounded but believe that it's likely not sparking when under compression when operating dynamically. Checked air gap and keyway, so I'm condemning the coil. This one's pretty worn out, so likely not worth the $15 for a new coil. Heading to the parts bin!

I have 2 of the same blowers and haven’t post them for sale since I couldn’t get them to run in optimal condition, even put a new carburetor and still have very erratic idling, and hardly ever stays running, unless I hit the throttle, already adjusted the carb and when it seems to be right the next day is acting up again, removed muffler and surprisingly there’s very little to nothing scratches, just a slight carbon buildup on the exhaust port, move the piston in a position where the exhaust port can be cleaned, also submerged the muffler in gasoline to clean all carbon, oil buildup, put it together and finally got a great improvement when starting it and now stays running in idle but still a slight erratic idling. I decided to disassemble the other (same model, got them a yard sales) and cylinder had a very slight fine scratch but the piston ring was stuck like yours in the video, I’m pretty sure that was the real culprit in those leaf blowers. My guess, home owners rarely run blowers or weed eaters full throttle, and they either plug up exhaust arresters, exhaust port or even the muffler, what I noticed when there’s buildup in the muffler or exhaust port the engine floods quickly or run rich. The other situation home owners don’t mix fuel and oil in the correct ratio, (worst case) they put in very little oil and that wears their engines and then come saying but it was running fine before it quit or the that before it started and run.

[@HomeGaragechannel]

yes I agree with you, run it at low RPMs and the likelihood that the piston ring might get stuck it very high on these. Also did you do a compression test?

I recently had one of these and the ring was very carbon jammed. Jug was nice, not scored, so I soaked it in pb blaster. 36 hours later, I destroyed the ring. Good thing I ordered the ring initially.

Thank you for your video. I have a 6 year old Stihl BG 86 blower and ran perfect until now. The engine suddenly stopped/seized up. I removed the flywheel and the 3 bolts behind it were loose and caused the back of the flywheel to get jammed. I tightened them up and it again ran perfect. I decided to take the flywheel off again and put locktite on the 3 bolts and now it barely starts and will only run on half choke, when I throttle, it bogs then dies. I use nonethanol gas. This is what I've done so far with no success, same problem with no changes: Checked spark plug, checked the air filter, checked the spark arrestor and mufler, replaced the carburetor, fuel lines and filter. Final item, replaced the tank vent and checked the timing. Note, when adjusting the H & L on the new replaced carburetor, nothing changes, still bogs/dies. I'm puzzled as what to do next, any help/suggestions would be great appreciated,

[@HomeGaragechannel]

the primary compression is a bit weak and the front crank seal is good.

[@tommyhanlon8012]

@@HomeGaragechannel it's the descending piston that creates primary compression & transfer, if the stuck ring is causing low primary & secondary ? 60 psi on a 4 stroke is enough to get the engine to cycle, perhaps a 2 stroke may need a little more pressure with their configuration ?

nice idea but I am not free, during that time slot.

[@fwflyer78]

I think that it will come down to low compression as to the reason why it would not run. Eighty PSI, from my experience, is a bit low for a two stroke to run at all. It will be interesting to see how much the compression increases when you button everything back up. The only other thing that it could be is a weak spark from the coil.

[@HomeGaragechannel]

you are correct about the spark from the coil, and yes hopefully the compression increase enough to get it to run

[@watermanone7567]

Good job cleaning the ring and groove, make sure to clean the carbon out of the exhaust port as this can make issues with low power or not starting. Also try a different spark tester, I like the jump the gap type as sometimes the orange glow type will give you a false test. Thanks for the video.

[@HomeGaragechannel]

yes I should have cleaned the port better, thank you Waterman one.

[@mattwickert736]

I had 2 partially stuck piston rings this year on different equipment. They were both from the company that cuts my grass. New rings, gaskets, seals, and they ran like they were brand new. I probably could have just done the rings or cleaned the carbon and put the rings back on. But, considering their use, it's better to just replace those while the block is apart. Both machines had compression readings in the 75-80 range, so when I saw that on yours, my first guess was piston ring if not a scored piston/cylinder. As long as the ring wasn't too worn on the outside, the cleanup should get sufficient compression for it to start and run again. It looked like there was some carbon in the exhaust built up too (hard to tell on camera), which I try to clean up a little as well for better air flow.

[@HomeGaragechannel]

nice work! and yes after freeing the ring, the compression does improve quite a bit.

[@danielpagel4272]

Check the ring for a flat spot. Years ago I took two Poulan blowers of this type apart and in each case I found a flat spot worn on the outer circumference. I bought a new ring for each blower and fixed the compression problem.

While 80 psi isn't ideal, I find it hard to believe that is the issue. I have an echo es210 with 60 psi compression (new ring and I ball honed the cylinder with no increase in compression) but it starts and runs well. I would lean more toward a coil issue/weak spark or an air leak somewhere. I would also use a better oil to prevent that carbon build-up. I run Echo Red armour @ 50:1 in some equipment, and Amsoil Saber @ 80:1 in all my new Echo's (pas2620, hc2210, and pb9010) . Whether or not that was THE issue for the lack of start it certainly was a issue for that blower Hopefully, you got it fixed and great video!!

[@electricannulus8854]

Checking the cylinder compression alone on a 2 stroke, only gives you a small picture because of the way air alone enters the combustion chamber. Two other areas to check are crankcase pressure and crankcase vacuum. Crank vacuum is what air into the engine and unlike a 4 stroke, the air does not enter the combustion chamber from the intake. Air and fuel are drawn into the crank case where it is compressed and "Transferred" to the cylinder for compression and ignition. There are several ways that the crank vacuum and compression are achieved (piston port, rotary valve or reed valve, however all require a good seal between the piston and the cylinder near and to the bottom of stroke. If for any reason, there is a crankcase leak sufficient air and fuel will not be drawn into the engine. Also, there is no float bowl so the main jet fuel supply is governed by a built-in fuel pump and needle valve. All of the fuel pumps are powered buy the fluctuating air pulses in the crankcase and if they are not sufficient, no fuel will enter the engine. The simple task of freeing up the sing may and probably was sufficient to restore proper crankcase seal and and allow the engine to start

I don't know if that blower ran but I have an identical blower with identical non run situation. I am stumped. short of replacing the cylinder and piston, I can find no other solution. I am open to suggestion.

[@HomeGaragechannel]

did you watch the entire video? I fixed the blower and the problem Is very common on this model

[@tylerkratz7]

What are you spraying and rinsing to clean the outside of the blower?

[@HomeGaragechannel]

I'm using the gallon size degreaser from Harbor Freight and using water to rinse

[@Jo-YuriLover]

What hex key did you used? And would adding some MMO to the mix would help prevent carbon build up?

[@HomeGaragechannel]

can you give me a time stamp on what key you're referring to? no MMO, won't help in that regard.

[@Jo-YuriLover]

@@HomeGaragechannel Thanks for the reply. Hex Key aka Allen Key.

[@gilpicard6024]

Got 3 of these with no run issue , replaced rings in all and cashed out.

[@HomeGaragechannel]

nice work!

[@djtrainman2]

Could it be something to do with the stop switch

[@HomeGaragechannel]

no the ring was stuck to the piston.

[@paddyman9603]

I would say spot on with the low compression causing non-start, however the cause is probably using the wrong type 2-stroke oil, some people will mix in any type they can find and if its castor based or racing spec it needs higher temperatures to burn off cleanly, if the engine is running cooler than the oil was designed for the unburnt oil turns into a gummy mess and cause ring sticking & port clogging.

[@HomeGaragechannel]

thank you Paddy Man .

no problem

[@charliee7142]

When you tried to start it with the drill you were going backwards ?

[@HomeGaragechannel]

no I was not, confirmed it twice, besides going the other direction, pulls on the rope for the recoil, and won't allow you to turn it over. Thanks for trying tho.

[@Amedeus1756]

Do you think that Sea Foam or any fogging product might have worked on the stuck piston?

[@HomeGaragechannel]

at the point it's at, No. It would require something stronger, like saoking in b12 carb cleaner or a strong acid.

[@hosta3199]

What did you use to clean the carbon off

[@HomeGaragechannel]

you mean on the piston? Carb cleaner seems to do a good job otherwise oven cleaner

[@markharris4260]

I haven't seen the next video yet but your going in the right direction , compression is low , 80 % forget it , you need at least 100 psi minimum and 120 to 140 psi would be great ! As foe a real shop , your doing great ! Someone ran that blower with less than adequate premix ratio , yes it probably states 50.1 mix but never ever run a poulan blower like that one on anything less than 40.1 ratio premix and make sure it's synthetic premix oil , echo red armor or my personal choice mercury quicksilver 2 cycle marine premix at 40.1 ratio , as for checking the ignition timing thats not a bad idea but I have never saw a flywheel that stripped or jumped keyway on that type of set up !

[@HomeGaragechannel]

thanks, and the next video pretty much sums it up.

[@kyotocrimeclub6406]

i wouldnt say you went in the wrong direction sometimes engines are just complicated rabbit holes. but the only thing i thought to check that i didn't hear you say was fuel pump/sending unit

that's weird, I check the "held" section all the time and I haven't seen any of your comments there, so they should be showing up , like normal. As for the least favorite brand, I don't have one, but I do have a "STYLE" of engine, that I don't care for, and it's the one with the spark plug, on the bottom.

I have taken my 15+ year old Poulan apart so may times to fix shit. Luckily never that. Have to say, I had no money when I bought that thing and it still is useful as a backup blower.

[@HomeGaragechannel]

to be honest, I really do like this style of blower, and I don't have an issue using one everyday.

[@Satoriga]

4:55 would it be in start position?

[@HomeGaragechannel]

since I added fuel to the engine, I have to try and start it in the run position otherwise you'll end up flooding it in the "start" position

[@NerfCraft]

I think freeing the ring will get this engine working again. Definitely not supposed to be stuck, and 80psi of compression really is on the low side. I don't necessarily think that 80 is enough compression to make this engine run, probably depends on the engine, but I'm guessing this one is set up in such a way that it needs more than 80 psi to work properly. The only other things I can think of are that either fuel or air got blocked off somehow, but you bypassed the fuel system by putting fuel directly into the engine, and it didn't appear to have anything keeping air out, so not sure what else could cause it. Maybe exhaust/spark arrestor clogged somehow? Any mention of how well it ran the day before it wouldn't start?

[@HomeGaragechannel]

unfortunately no, I wasn't given that information

That's a tough call I would have gone the same way You did to save some money Understandable that it is extremly frustrating .
