Dan Carroll: Well' after reading all the comments here on the PB Echo 250 ?? I have had mine for 7-8 years,have dropped it off my truck a dozen or so times, left it out in the winter and used it as a snow blower for removing snow off my truck. And in the summer ' it get's pissed on from the heavy rains we have up at the cottage' not to mention the very cold winters,and it starts every time, AND WORKS LIKE A CHAMP. I am afraid to give it a tune up.....for fear the dam thing won't run the same. Now I do use regular gas and Echo gas mix.......must of been built on a Friday' or maybe "A" longgg wknd Friday???lol...

Cliff Crowley: My problem is a bit different. 2016 PB-250LN. Worked great for 2 years. It starts and runs fine for a few minutes, then when it warms up at WOT, it will not stall, but it will cycle rpms from high to idle for about 15 seconds, then back to up to full throttle. This happens about every 90 secs. Should I just try a new carb? Our local small engine shop won't even look at big box store crap. They say throw it out and buy a new one. They charge 75 pct of its cost just to look at it.

Miguel Plascencia: Hey the old one with the walbro carb is the best one you can adjust it at low and high throttle the new one sucks

Brandon Gump: I have the newer model. I've had for 3 years now. A month ago I replaced the lines, fuel filter and primer bulb and threw in a new air filter. I usually change mine monthly just because their inexpensive ran great. It sat for 2 weeks without running and now it run right. It will start and idle for a short time then stall out or if I give it any kind of throttle it just dies. I have a used pair of hedge trimmers do the same thing the changed out the carb and it runs like brand new. I think I'll do the same to the blower now

Zachary Coslic: I bought the es 250 best blower!

Carl Kahler: I think you have it backwards the Zama RB carb's are total crap the walbro's are way better i have my own shop and the RB series Zama's are just crap.

Clay Blasdel: camera shake it too difficult to watch

robulusx2: I have the same problem, I just buy a new carb cheap online for 15 bucks and replace it every year, but yeah it's junk.

The Sovereign of America: 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.

Isaiah40:22: 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
