Thank you for this video. It helped me finally fix my 770t. Echo replaced my entire engine but not the carb. Even after that it was still bogging and running hot. I kept telling them it was too lean and always told carb was set right. About a half turn and it runs like a hero. No more bogging and it doesn't smell like it's overheating. It smells like a 2 stroke should! And it has a noticeable amount more power. Thanks again for the information!
The current # for that tool is: Echo Walbro ECH-91159L but it can't be had cheap. AliExpress sells similar for under $2 but it's too short. If you buy one of those multi sets of drivers, the metal section needs to be at least 4" long or poss. loose your warranty & enlarge the hole to get closer to the carb. I do not know if one of those multi sets has a micro D that fits! YOU CAN MAKE ONE as I just did for .50 Ace Hardware, find the selection of tension pins, get the smallest, 5/32 x 1, not shortest; close it's gap & you have to grind it thinner BUT THIS is the only metal that is still strong enough to do the job. I put the pin in a vice so I could pound something into other end to make it long enough (Use long thin flat head) I tried everything before this as I won't give Echo (on line for $19.04 + 5.98 shipping) that much $. ***ALSO *** E-bay sells China carbs for the 770 for $15!. I saw a vid & it looks easy & worked great (so far) & HAS A FLAT HEAD ADJ. SCREW!!! I hope I've helped you as I banged my head for the longest. (edit: in my exp. all used blowers are slowed- down by a clogged spark arrestor. it's a screen at the exit of the muffler that 2 cycl oil has clogged. Throw this useless screen away BEFORE anything else!) I'M NOT SURE I even recommend this anymore b/c this tiny adj. screw is real stiff to keep from vibrating out of adjustment & it is tiny. My system might round it off so MAYBE replacement w/ a Chinese carb w/ a flat head adj screw is better LISTEN: The BIGGEST, BIGGEST improvement one can make is to lengthen that short blower tube. Being short (5' 8") I just unscrewed both tubes & connected them about 2" into each other then used strong black tape. If you're taller, you may need to order an extra section & fabricate. The end of the tube should be 2-3 feet away from your feet with no hands on. I AM NOW RARELY USING full power so: longer life more satisfying performance! One last clue. If you're adjusting any 2 cycle carb that has a slow adjustment, do not touch that adj. screw.
I am going these tools and try this thanks. Also thanks for the trimmer video. I am not even going to tell you how many trimmers I have sold and bought new again just because I never knew. Thanks again.
You got a link to the tools i can use other then these blue ones?..i heard you said you,you broke the long one an order another one also is the short one needed
Looks like a 5/64 tension (get the longest @ Ace Hardware) will fit onto the carb adjustment. First use penetrating oil on the tiny adjustment stem. Echo stop selling any adjustment tool. Open just a hair! Do nothing else but there are clues in my other posts here. (find that pre air filter etc)
I have a 770 same issue. Watched your video and made the adjustment and it worked, problem is I have to keep adjusting it over and over. (The high side jet) Is it loose shaking itself out of spec each time?? Legit have to adjust it every time I use it and sometimes while using it! Any insight on that sir?? Thanks
is there high and low needle adjustments on these? if so, how do you tune the low needle? also, factory settings like number of turns on both needles would be helpful.
Hi! I have a 500T. It sat for several years. SO, I replaced the carb, fuel filter, spark plug; and the fuel, of course, adding a touch of Seafoam. It started right up; but wouldn’t maintain idle, snd then wouldn’t te-start. I found the coil resistance way too high. I’m surprised I got any spark at all. I replaced the coil. Now, it starts right up on full choke, snd idles beautifully with the choke off. When I go to increase the throttle;however, it wants to cut out - lower the throttle and it returns to idle. The most I can give it is half throttle. Would this be the high adjustment? Which way do I go with it, if so. I don’t have the adjustment tool. Some on UA-cam use a flattened roll pin.
My Echo 770P works Great for the first half tank of gas.After that it wont take full throttle and bogs down.Also, it wont turn off.I have to pull the cap off spark plug to turn it off.After sitting for a hour it runs great again; but still wont shut off.It use to shut off the last couple time i used it.Any suggestions on these problems.
You’re a “PIMP”!!!! You rock bro! Does the 580 adjust this way also? I just picked up a used one and I want to go thru and make sure it runs like it should.... SUBSCRIBED!!!
Have 770t new carb running fine then 2 weeks later bogging our again tried adjusting as per your video no change. New carb. New plug. New fuel filter clean air filter. Any other ideas? Thanks
You showed the tools you bought online the blue d shaped ones but didn’t you use the black one that you had on that table to adjust the carb that’s what it looked like when I was watching the video it kind of trew me off since I found the blue tool online but wasn’t sure if it was the right one
just bought a 775 2 days old, used it 20 mins after taking a break, now wont start period... GAS\oil mixture is fine as this is being used in various other tools.
S_J_P I never have. Some people do a say it performs better without it. I leave it on for safety. Couple screws and you can remove and clean it if it’s carb up
Jonquil lawn & landscape if you take that out and the deflector that holds it, the half moon 1, it makes more noise, and it feels like it's more responsive we u accelerate
GOOD NEWS: Echo 91186 for only $11 is the adjustment STEM ONLY B U T if you squirt some spray oil in the hole where the (very stiff) carb adjustment is, it becomes much easier to turn. That is what was actually needed. I believe the 50 cent tool will work now! Just open it a TINY bit & FORGET IT otherwise you'll get lost trying to find the sweet spot. Don't skip the last paragraph below.
Of course, this is a scam for these repair shops. They know these do it yourselfers don’t know shit about adjusting these carbs. These people drop off their machines and get charged a lot of money for something so minuscule
Walbro “long D” and walbro “large D” eh? So the long d is long and skinny and the large d is shorter and fatter? Think the guys at walbro were laughing their asses off when making those took names?
You naiked !Helped me immensely. First video I found that showed me exactly what I needed to know ! Thank you , I'm now a dedicated subscriber.

Thanks - just did this and solved my problem. Got a good set of the tools on Amazon for about $15. Appreciate the help.
ggnoodles1 broke the factory tool set and bought another off amazon. These blowers need slight adjustment from time to time

I got my Echo 500H running great today!
Mine only starts at high rpm. It will not idle at all and seems to only have one speed (high) will this adjust it with only the high side adjustment?
Thank you I just been working. And just replaced the filter work again 😊
Does the 770 have a spark arrestor that's cleanable? If so, Id check that too if boggy

Yes, isn't there a 2nd adjustment? Other than idle

Thx buddy. But when you adjust carb you should have the filter on. Makes a difference with the air mixtures
Is there a plastic cap over the adjustment screw?

Lawrence Lightner not 💯 but should be similar
What tool are you using. Can I have the link or name of the item?
Have 770t new carb running fine then 2 weeks later bogging our again tried adjusting as per your video no change. New carb. New plug. New fuel filter clean air filter. Any other ideas? Thanks
Try new gas?
Do you possibly have a link for those carb adjustment tools? Thank you!
Doesn't counterclockwise richen the mixture and clockwise lean it out?
Joe Jirak correct
Mine dies on idle is there a idle hole and screw
what can I do my whip does not come out does not start the same sun
Good job on this dude. Well explained
Great Video, going to try changing the basics first. Thank you!!
The air filter has a foam pre-filter hidden behind the plastic retainer! I use Dawn then squeeze the f out of it
so is it micro d ?
Thanks for the great video!

Hey where did you get those screwdrivers to adjust the RPM of your blower
Lmao
Through and well presented tutorial. Thanks for the training ! Much appreciated. I’m going to have at it !
Daniel Dwyer good luck. Should work out for ya.
I have a Echo PB755ST. I'm seeing some sticky black sludge at the exhaust port. What is that and why am I getting this issue? Thanks!
RAS BKLion probably just carbon from combustion. Just keep an eye on exhaust. Carbon will eventually blue up spark arrestor
@@jonquillawnlandscape8491 Thank You!
my blower will only run with the choke set half way. it was stored over the winter with fuel in the tank . could the problem be old fuel?
Did you use any type of Stabil in the gas?
@@kennyplay5982 yes
@@588158 get a carb rebuild kit. 9/10 times it's a bad carb diaphragm.
Do you turn clockwise or counter to rev it up more
Josue Ramirez counter clockwise adds more fuel
Thank you.
Great video!
Hey guy, great video. Thanks
just bought a 775 2 days old, used it 20 mins after taking a break, now wont start period... GAS\oil mixture is fine as this is being used in various other tools.
Excellent video. Thanks for posting. Going to get online and buy that long d tool. Pretty sure this is my problem.
Thank you, very helpful.
Do you ever take the spark arrestor off? If so, does it make a big difference as far as running better?
S_J_P I never have. Some people do a say it performs better without it. I leave it on for safety. Couple screws and you can remove and clean it if it’s carb up

Doesn't turning high clockwise lean it out?
Greg Smilgin correct
What happens wen 1 of those run estroge for like 5 min and then shuts off?
Either the coil or check the muffler screen,spark plug
I have a 770 and I know it shakes when it idles. But mine shakes bad. Is there anyone who can help me with that
Thanks for the video.
PB-770H
2023 Everybody now lists these tools as "Discontinued" or "No longer available".
Of course, this is a scam for these repair shops. They know these do it yourselfers don’t know shit about adjusting these carbs. These people drop off their machines and get charged a lot of money for something so minuscule
👍👍
Can u post web adress of where u purchased that tool... Thanks
Locindo Nava no clue where I found it. I googled it
Do u need put motor oil ?

Lol Took names, hahaha
Damn. A camera tripod is your friend.
Why would anybody want a “Hip throttle”? 🤷♀️🤦♀️
I like it best!
I have a 770 works good for like 25 minutes and if i push the gas again it cuts off any idea whats issue with this blower
What did you find out? I have the same problem.
