Well, there are 2 adjustable mixture screws on that style carb. You only adjusted the high speed screw, and while that can fix it, often you need to balance it out with the idle/low speed screw. It runs down the inside of the throttle barrel, located 90° from the side screw you found under the purge bulb. There is a cover over this part on top that covers the throttle linkage, remove that, and looking down at top of carb you see the hole inside the shaft with a nut on the outside. It also has a plastic plug from the factory. Aftermarket carbs usually omit them. This is the low speed/idle circuit screw. Also have to coordinate the idle speed with the low speed adjustment, keep it at idle speed when adjusting the mix. ALSO, MANY times bogging like this where it just refuses to rev up is due to a plugged muffler spark screen, and/or carbon built up behind the muffler in the exhaust port! To clean out, remove the muffler run the piston to the bottom, and carefully scrape out the carbon to the edge of the port, blow out the cylinder from the spark plug hole before replacing the muffler. The screens are serviced without pulling the muffler, behind the small plate with a screw on the face by the outlet. Use a torch to burn the carbon out, or soak In Sea foam, or laquer thinner, etc. In this video, that PB250 was not revving like it should, still needs one or more of the above mentioned. 👍🙏

Exactly

I have an older style PB-250 with the high and low exposed screws. My repair guy told me he's not allowed to sell me the micro D tool to adjust them, sighting an EPA regulation. I had to grab a set off Ebay. Great hack btw.

[@jkronba1]

Thank you RPM! I took my Echo PB250ln to get serviced 2 years ago. Still didn't work right. I followed your video today with excellent results. I appreciate your time. If you are ever in Philadelphia and want to get lunch, it's on me!

[@timangus5525]

What a tip. Tuned mine up thinking that was the problem. After I got the plastic out it runs better than new. THANKS!!

[@anthonytorres9365]

Thanks !!!! Tried it exactly as you showed and each step work. The Blower is running great and power is back up to when it was brand new.

[@rpmimprovementoutdoorservi9968]

Glad to help!

[@USArmy91222]

little fresh fuel and carburetor adjustment, back in business again 👍😊

[@wyelandlebeouf7202]

adjusting while running is always best to tune the high jet on the carb with machine running and throttle to the max adjust it till it makes peak rpm then just a hair turn back in to keep the customer from blowing there machine up lol

[@johnbost3104]

Thanks for the video !! Worked on my blower. Kept me from buying a new won. 🤣🤣

[@JsCrazyCutzLLC]

You Tube to the rescue 👏 cool tip on exposing the set screw! Nice job 👍

[@rpmimprovementoutdoorservi9968]

J's Crazy Cutz, LLC 👍🏻 hope you all have a great day!!

[@alexandersteffen7805]

Great helpful video , well explained and concise. Thank you!

[@JARLandscapingLLC]

Glad to see you got it back to working! A couple of our string trimmers are having the opposite problem. They shut off once we release the throttle and they won't idle. So, we will be checking them out once we have more time! Great video👍🏻

[@rpmimprovementoutdoorservi9968]

J.A.R. Landscaping, LLC Sounds like you have some good video material with those repairs. 👍🏻 Glad you liked the vid!

[@markwestervelt1158]

Nice job! Very clear instructions and nicely paced.

[@rpmimprovementoutdoorservi9968]

Thank you. Thanks for dropping a comment 👍

[@BIGJAFFORDABLELAWNCARE]

Echos always have that problem. I had the same problem with my srm. Took to the shop and it was the fuel filter. Which I could've done myself. Thanks for the video👍

[@rpmimprovementoutdoorservi9968]

BIG J AFFORDABLE LAWN CARE Honestly we try to do as much on our as possible. As long as we have google and KZbin we can wing it 😂🤣 thanks for stopping by and watching!!

[@markmoore338]

Thanks for the vid. I did this after changing filter, spark plug and cleaning the muffler port(other video on this). Still no go. It ended up being the fuel filter in the tank, which was original- about 7 years old. Also, I could access the screw with out removing any cover. There was some outside ring I tried to get out but then I looked closely and saw the adjust screw and screwed it back and forth. Did not solve the problem. Again, the fuel filter was old and clogged.

[@jamesrichardson771]

Wow💥 thank you So' much! I'm having this exact' problem, with the same model blower . 🛠

[@davey201111]

Thank you for the information. I had changed my carburetor and still didn't fix the problem. I will defiantly let you know!!!

[@monkeywentbananas]

Used your heat method to remove that plug. Worked perfect!

[@MOWTOWN]

great info keeep up the good work guys

[@rpmimprovementoutdoorservi9968]

MOWTOWN thanks for taking a bit and stopping by!

[@claddagh1000]

I did the heat trick to a Husqvarna bt150 and plug came out and adjusted it , runs mint

[@rpmimprovementoutdoorservi9968]

claddagh1000 Sweet!!

[@bkboyes1]

My echo started bogging, then only run at idle..dumped fuel, cleaned all.lones, same problem. Followed this video and it now runs as good as new. I only run the premix cans you buy, trufuel etc..so I usually don't have a fuel.problem

[@joe4hirelawncare497]

Great video guys! Keep up the great work.

[@andybecker2693]

There’s a low speed needle adjustment on the top of the carb where the throttle pivots. It is under a brass plug. You needed to adjust it also because now it is too rich on the high speed needle and is blubbering and not reaching full rpms. It is a lot better but if you adjust both screws you’ll have great throttle response and the recommended top speed. Google the specs and use a tachometer only for the high speed needle adjustment.

[@Kuhlyedascope69]

hey Andy I was given an echo pb250ln from a friend who couldnt get it running. I got it running but it would bog down at full throttle. I simply adjusted that nut a few turns and bam a running leaf blower. thanks yall

[@xmodusoperandix]

@@Kuhlyedascope69 thanks for this…fixed my issue didnt realize there was two adjustments to this carburetor…did the other one with no luck…this one fixed me!

[@jonathanbenoit8828]

Good work 👍, fuel mix is too thin, needs more oil in the fuel should be smoke from the exhaust ports.

[@rpmimprovementoutdoorservi9968]

Great point!

[@rgm9400]

Thanks!!

[@nevillestephen1135]

Hey I have a PB 252 is is kinder the same what you have there. I have that same problem but sometimes there's a knocking in machine as well. The don't happen often and I don't know what to do.

[@happysfamilywnc]

Nice vid!

[@rpmimprovementoutdoorservi9968]

Happy's Family Thanks folks!

[@rickwatson7423]

Mine just started doing that bog down and then I adjusted the high idle and started running good then ran it full throttle then it just died

[@isaiah9696]

I made mine to work adjusting this little hidden screew that you showed,but everytime I used it, i have to adajust it again, so i dont know why it has to be like that, any ideas how to fix it permanently?

[@joeflores4539]

Did you ever figure this out, i know its been a while thanks

[@upscalelawncaremonroe408]

My Echo does the same thing

[@rpmimprovementoutdoorservi9968]

Upscale Lawn Care Monroe Hopefully this video might help you out. Thanks for watching.

[@artemorbid]

Good day my friends. I have always wondered how these worked and you did a fantastic job demonstrating all the features on this unit. I had no idea it used gas, are there alternative unit that maybe run on something else? I remember buying a lawn mover that was completely manual but since I moved to a high rise I had no need for it anymore.

[@xmodusoperandix]

any ideas on when its not the idle?…i have less than 20 hours on my es-250 and ugh just did all of this for it to still be bogged down….im thinking my throttle might be wrong after disassembling other than that i have no idea

[@rpmimprovementoutdoorservi9968]

Possibly an issue with the fuel.

[@xmodusoperandix]

@@rpmimprovementoutdoorservi9968 apparently there is another brass screw on the top side…tweaked it and got mine to work some one pointed out in this comment thread about it…i didnt even notice it until they said it and went and looked at a new carburetor on google images and saw it

[@rpmimprovementoutdoorservi9968]

@@xmodusoperandix Awesome! That’s what is great about this community. Lots of folks with knowledge to share 👍

[@woodnyardjunkie]

Prob could just use a easy out.

[@berfsmith6196]

Do you put the little thing back in or leave it out?

[@davidrasmussen2975]

leave it out. it is there to try and prevent you from adjusting the screw. EPA wont let you enrichen it for fear it will produce more unburned hydrocarbons. Use synthetic oil and it will burn cleaner and not plug up spark arrestor screen as fast either.

[@francisappleby1190]

Won't start or run

*Exactly what I expected from a brand like Hitachi **Bestfor.Garden** also recommend I’ve only had it a few weeks now, but really happy with what it does. I assume it’s like anything, if you take care of it, it will last along time.*
