This is what happens when you play back Surfin' Bird at 1.5 speed. He is ok, he just bumped his head at the end.

Just messing around at Stonebriar with the GoPro to see the camera's resolution. I think a body mounted GoPro is the next test.
Same issue. I’m having a head time removing the original flywheel. Seems seized on the shaft. Any suggestions?
Hmm, I'm thinking the metal from the integrated key has lodged itself along the shaft. I'd suggest putting a few drops of Deep Creep (or some other penetrating fluid) and let it sit for a day. Then, gently, ever so gently, apply some pressure from the inside to encourage it off. Good luck, let me know if you are successful.
Thanks Robert, I got it off! Pb blaster plus a solid tap with my channel locks. There was some mild surface rust on the shaft the flywheel sits on.
@@kellycarpenter2427 That is AWESOME! I'm glad you got it off and are on your way to getting it repaired. 3 years later and I still have this blower in use, so I'm glad this video has helped some people. This problem has probably sent many to the junk pile when it could have been fixed. Good luck with the rest of the repair! Robert
Yet I m another person you helped. Mine I thought was old and needed replaced since it died like everyone elses. Was on Home Depot site looking at new ones, and reading reviews someone complained about the flywheel pin breaking!! So I looked up the model to see if I can still get parts since this one is pretty old.. And see I can get it, so I jump on a search to replace and you video popped up and Im sure you found my problem!! So I still have to take it apart, and am sure Ill see the issue that you explained!! Thanks!!
@@terrythomas790 good luck with the fix, it isn't complicated, just take your time. Years later and this blower is still going strong.
@@robertirving6326 Ill be able to handle this, but am curious of that rope. Did you put that in there so you would be able to tighten that fan part back on. To keep the engine from turning as you tightened it?
@@terrythomas790 correct, I stuck all the cord down the cylinder to bind it up and not free spin while tightening everything.
@@robertirving6326 Thank You! Happy leaf blowing!!! lol
Mine went from working one day to not and made the strangest rattle sometimes when I’d pull the rope. I love this blower and I’m 99 percent sure this is the problem. I did have a coil die some time back but it’s not that, because at some point after this problem I guess the flywheel was in the right position and actually ran fine for a little.
Hows that flywheel holding up? I actually grinded it out and reused the same flywheel. I fashioned a key out of some shaved and grinded woodruff keys (from Harbor Freight)
Two years later and this machine still fires up every time! I use a backpack blower for my main work, but this one gets used twice a week for the garage and back patio. Still good.
This video helped incredibly. I had fuel, air, and spark but not a hint of starting. After watching this video and relating to his burning desire to figure it out, I started the quick tare down to get to the flywheel. The key was sheared as described. I ordered the part and when it came in the assembly was quick and easy. After getting it all together it started easily on the 1st pull and pretty much the 1st pull every time since. I can't imagine how many of these end up in the landfill because of this very issue. Thanks for posting this video, extremely helpful and even a little fun!
Thank you John! I'm glad this video helped, and I appreciate you taking the time to write your comment. Yes, how many perfectly good blowers end up in the trash when they can be fixed? This blower still starts for me every time I pick it up! I'm glad it helped, and thanks again for your kind comment.
In the hopes that this may help in the future, here’s what I always keep thinking of when I’m diagnosing. FACTS - Fuel, Air, Compression, Timing, Spark!!! Easy to remember and covers all the basics. Bear in mind that Air means air in as well as out (exhaust).
Going to look at mine it just quit and 😢 tried a bunnch as you did but not that far yet. . Going to take it off and see?? Thanks for the information much appreciated 👍👍
so i took mine completely apart and the majority of the screws for tightening the plastic housing to itself are the same length etc.... there is 1 singular screw that is longer than the rest... and wouldnt you imagine.... i cant find where it goes.....
I completely understand this statement. From experience, when you find that odd screw, make note of where it came from. I hope you resolved it, this blower is still going strong today.
After looking how to fix the problem in you tube for hours I found yours that matches my, and same model of blower. Thanks for the help. Where did you buy the part?
I'm glad it helped. I ordered my part off Amazon, but that part is probably available from other suppliers also. Good luck with the repair.
Thanks for the great details! Even with the sheared key were you still getting a spark?
Yes! I was getting spark, so I knew the ignition coil was functioning. The only issue, I was getting spark at the bottom of the cycle, not the top. That's what drove me nuts trying to figure out the problem, not until I looked at the flywheel orientation did I have my "ah ha" moment. And, this blower is still running like a champ today! I'm glad the video helped.
Unfortunately I have the sam issue, and as a start I put the original flywheel back in on the blower in the correct position, started right up, so what I was looking for is someone who repaired the original flywheel, this situation has been caused by the manufacture trying to save manufacturing costs at our expense, when I looked they wanted 40+$ for a new one.
I have the same exact problem on my Echo PB-265L backpack blower. It has the same flywheel.
This part must be common across several products, (blowers, edgers, trimmers). But I still have this blower and it has been running like a champ ever since the fix.
I just ordered a new flywheel. I am confident that it will resolve my non-starting problem. Thanks for posting this!
found a deal on one of these + another similar model echo for cheap and a cheapie trimmer. May risk it for $8.33 each. Hard to find a free name brand blower.
If the woodruf key as sheered off how it was possible to crank the engine???
There is no separate key, the equivalent shape of a key is cut into the metal of the flywheel. The metal is soft, so it gets mangled and out of alignment. As far as cranking, there was enough metal jammed around the crank that it would grip and spin. But it is a scraped part, no saving it. I still use it today!
Hi Robert, Thanks for posting this video, it was exactly the information I needed to fix my PB-251. When it stopped working I took it to the local small engine repair shop and they told me it was most likely a sheared flywheel keyway, and it was a really complicated repair, they would have to take the whole engine apart, blah blah what would a woman know of these things... and probably not worth the expense to fix and I should just leave the blower there and they'd dispose of it. But.... I didn't buy their explanation, so I returned home with my blower and proceeded to search the web for repair information, and then I found your video! I ordered the replacement part from Amazon, and following your video, it was a super easy disassembly (literally only 7 screws to remove) and re-assembly with the new part (the flywheel keyway was indeed sheared). $73 later I have a perfectly working blower, thanks to your helpful video!
I love your story! So glad the video helped. I still have this blower today, and still running great.
I have just gone through my echo pb-251 for same problem. Won’t start even after checking spark, carburetor replaced, exhaust spark arrest clean, still not starting! Driving me nuts! Got online and heard about common problem with this model blower. I’ll check flywheel key tomorrow. I bet that is what’s wrong with mine also. Thanks for posting this video!
Good luck!!
Robert, is it necessary to replace the complete flywheel, or can JUST the key be replaced? I've replaced the carb, fuel lines, and filter, and have compression. This has to be my problem!
It is all one piece, but don't let that discourage you, once the damaged one comes out the new one will seat nicely. Good luck!
Thank you . I came across your video last.week. My 251 would not start and everything checked out good. Then after seeing your video I checked my fly wheel and it was bad. So I ordered a new one after I ordered a coil. So I got my flywheel the other day I put it in put it back together without putting a new coil in. Got the machine back going and it started. So now I have an extra coil but you never know when those go bad. Thank you so much. And I had the whole thing taken apart. And I got it back together okay. Thanks. And that's after not working for 2 years.
I'm glad it helped, this fix drove me nuts trying to understand the issue. Glad you're up and running!
I’m picking one up tomorrow for 40 buck
Hi Robert. Your are not alone. On m’y PB-251, 3 days ago, i found the same problem and symptoms. Small key completly worn off. The screw does not push the flyweel properly.
any idea why the key sheared off?
There was not a separate physical key, it was the way the metal plates were cut on the flywheel/ignition to include the shape of a key to slide onto the shaft. The metal just deformed and allowed the flywheel to spin around the shaft about 180 degrees. Tough diagnosis, but that blower is still running like a champ today. I'm guessing a stick got caught in it somewhere, causing it to stop abruptly. It was a throw out from someone else, I figured I could adopt it.
@@robertirving6326 I understand. I think they make an upgraded replacement flywheel now. It's made of metal and uses a real key. apparently that happened too often.
@@jmb92555 do you know the part number? Thanks
@@kchilz32 If you mean that upgraded part, apparently I was mistaken. It turns out someone milled out the oem flywheel in a way that he could use a key
