Mac Chisolm: Ethanol is your enemy leaving any two cycle for a month without running it. Sta-bil is your best friend when non use for the winter or between use is lengthy. Make sure before storing it has Sta-bil in the gas tank and runs through the engine. Make sure your spark arrestor is clean each season before storage. Use sea foam periodically to clean carbon deposits in the engine as directed. Replace air filter, hoses, and gas filter each season as well as installing a new spark plug gapped to it's specifications in your owners manual. One should only have to rebuild the carburetor on these engines once every 4 years if you combat ethanol. You can also use non ethanol fuel sold at hardware stores but it is costly if your equipment is for commercial use. I've had great success following these guidelines for years in commercial use.

Derek Macdonald: I'm on 3rd carb since 2011. waiting for new one now. i even cleaned last one still nothing, waiting for new carb. just wondering if i should just buy a sthil.i got 6 year old sthil chainsaw with no problems ever

Alex Tafoya: I had the same problem thank you for saying that to me thank you.......

BADFISHHHHHH: So my new SR-225 trimmer was running like crap and bogging down at WOT so i found out the new version carb(new emision laws?) has a hidden adjustment screw hidden behind the brass sleeve and plastic which is under the primer. I drilled mine out and got a flathead in there to back off the screw some and it ran awesome afterwards. I'm so happy.

Mark Mullen: I just bought the PB 250 for $149. It runs like crap. Except when I bring it into the shop to work on it, then it's fine. Either it has a break in period, or it's a lemon. I regret buying it, and not getting the higher end blower. I'm wondering if it's set up to run the higher octane non-ethanol fuel. I was hoping just to use the new premix near the end of the season to cut cost. I bought it from a lawn mower shop, and not Home Depot, or I would be returning it for the better one. I've had 10 other echo's and this is the first dud. It feels under powered as well, compared to my PB 230L.

Michael mcgourley: Hey, I blame all the problems, with ALL brands, with the small 2 stroke carbs, on ethanol fuel. I started buying the ethanol free gas about 5 years ago. I only use about 20 gallons per year on my lawn equipment so, even at $1.00 more per gallon it only costs me $20.00 per year to be problem free! Another trick is to run your equipment dry at the last use for the season. These small carbs only require the smallest amount of sludge, gew, lacquered gas, or whatever you want to call it to clog them up. I hope this helps everyone. If you already have the problem with your equipment go to harbor freight (I know, most things suck there but if you don't use it much the tools will do the job) and buy a sonic cleaner. the one big enough to fit the carb in. Take the carb completely apart. Sonic clean it. You have to use the heat setting and cycle it many times till you have an hour or more of cleaning time on your carb. Purple simple green works well as your solvent. Put the complete rebuild kit in when you reassemble. It should work fine then.

T Bone: I have the 260 backpack version that's at least 6 years old. It starts up with with just a few pulls even after a couple months of sitting up. But the carburetor is crap. will only run on 3/4 choke.

Alex Penfold: The problem is they are a scamming bullcrap company like most.. of course dealers will buy and push a product that within a year will be in the shop. Covering Carb adjustments and selling dealers special tools not sold to public. BS !!!! every single 2 stroke on earth will need a carb adjustment at some point! had this same blower 1 season and stopped working ! finally found the carb only need more fuel (H screw) Which i did manage to adjust without their scam...I mean special tool. just took the plastic off half an electrical connector slightly crimped it and jammed it on the adjustment screw. This guy is an example of why a good product is bad business! suckers! don't buy into the BS anymore !

belyeu4190: The problem with echo is they don't last and degrade with use. The engines don't wear out, they just won't start because of fuel issues. So, what is the solution. Once a year change the fuel lines, air filter, plug and install a carb rebuild kit. If you can try and run fuel that is alcohol free. Power mower shops sell pre-mix but it is expensive. Don't bother taking your Echo in for the phony 5year warranty because they will never ever honor that warranty. The least little dirt in your carb will cause major problems and old fuel with alcohol is toxic to Echo blowers.

Rednecks For Jesus: I am working on a PB 251 and when I start it up it won't throttle up. I bought another carb off of ebay and it still does the same thing, won't throttle up. I also took off the spark arrester to see if it would throttle up with no luck. Any wisdom here guys please?

john scimeca: if your blower as half the power and it is about a year old it the screen on the muffler is clogged if you look at the  muffler there is small cover with 4 screws that shoot the air to the side remove the screws and the screen throw the screen away and it will run on full power

BERTO929: I have an Echo PB200 that I have had for approximate 7 years, it ran decent for a while then i was only able to use about half throttle. I think it just needs a good carb cleaning. I think it's time for a new blower. I didn't realize Echo had so many bad reviews until I started doing research on which blower to buy. I have an echo trimmer that I have no issues with. I'm looking to purchase a hand held blower in the range of 400 CFM. My question is, are the new 2014 Echo blowers more reliable than the ones manufactured just a few years ago or should I go with a different brand? If so, which one?


Robert Coltrin: I also own the PB250 leaf blower.  A real piece of crap! lasted one season and won't start.  Took it in to dealer twice, started once after that, then no more. 2 trips @ 70 bucks a pop, pays for new blower.  I now have the stihl.  I fires up everytime. is lightter and the air intake  is on the side away from you pant leg so does not suck it in and quit blowing.  Much nicer and actually less than the Echo.  I have many other echo machines but the blower sucks.

obumbrabit: thanks for the informative video showing the difference in the carbs

maelizama: Spark arrest is the problem. I have both of these. Very easy to take apart clean and also clean muffler and
 your ready to rumble! Mae

David Kaniecki: Same problem with 2012...ECHO is junk.  Took it to dealer twice...same issue.  After 1st season it won't run at high RPM.

maelizama: Very good video! I had problems with the 2010 blower. still do. I love the Echo products. Just like anything else you can iron out the kinks or ignore them. I think Echo is on the right track by making their products better. Thanks!

TBrockSki: FIXED IT!!  My neighbor has the later version PB-250with Zama side primer bulb, EPA tamper proof carb.  Nothing but bogging above 1/2throttle.  I removed spark arrestor & retried; no improvement.  I removed entire muffler and found the exhaust port of cylinder was clogged.  Ran piston to BDC, scraped out carbon buildup, blew airhose in through spark plug hole to clean, reassembled it and it runs like new again. Try to use a plastic or wooden pick or scraper to clean out carbon to avoid damaging cylinder wall

Doug Luciano: I have a PB250 (MFG 2010), these are complete junk -do NOT buy

capitolemiproducer: Hey I know what's wrong with your blower. I contacted ECHO about my PB-251 about the same problem. The exhaust has a spark arrestor and if you mixed your fuel with too much oil, it will clog it. Remove it clean it well, and it should fix it. Let me know. Hey record it and put it on youtube. I wish I had done that when I fixed my blower
