Really appreciate your video as it was clear, to the point and engaging - I learnt a lot. I’ve been mulling over purchasing this unit (the Pb770T version) after seeing its performance last winter as my neighbour kindly cleared our front yard and steps many times. I just can’t manage the walk-behind snow thrower any longer and just sold it. With the in-dept knowledge gained from your video I’m more confident to buy the unit and will purchase it today with the funds from selling the snow thrower. Thank you.
Nice job explaining the overall problems with this unit. I am currently troubleshooting an ignition coil problem. I have no spark currently and a new coil installed after a broken spark plug coil wire was found. Will let you know my findings. Thanks Wally
Wally, great video. I just bought a PB 770H at a g-sale cheap. It looked like it was well used/dirty but started on only 2 pulls and ran great. It needed new straps, flex tube and I replaced all the fuel lines, air filter and purge bulb. The kill terminal on the coil was loose and wouldn't kill the engine. I inspected the cylinder thru the spark plug hole and it looked perfect. I wanted to pull the muffler but the bolts are super tight and I didn't want to risk shearing them off. Glad to hear these things are pretty reliable.
I found one of these that was left for dead. Siezed, no spark plug, water in cylinder. I put in some WD-40 let is sit for a week. I was able to free the piston, i put a carb kit in it. I actually started and has been running for 6 years. I do about an acre of leaves.
I'm cheap so whenever I get one in to flip with a bad muffler I put on a pb403/pb413/pb603/pb500 muffler. The bolt pattern is identical and the gasket is the perfect shape as well. At first I was worried that the smaller muffler would restrict the air flow, but it does not, atleast not noticeably
Great Video! I usually duct tape the anti-static wire to the id of the tube if it bothers the customer which to some it does! Anything for a Buck I say!
Mine seems to turn off after I start putting throttle, if I leave it to simply idle it’s fine. As soon as I get on the throttle it works for about 1 minute and then gives out turning off completely. Also once it turns off it shakes pretty heavy right as it turns off. Any idea what if could be?
now i know why i was always hearing that clanking noise when the blower got hot. the wrist pin. after about 45 minutes of use it would start clanking. but just got rid of it and got myself a 9010t from AZ Lawn King
I was using my blower today and it just shut off on me as if I pressed the kill switch. I brought it down to an idle and it idled for about 10 seconds and just shut off and then I couldnt get it to restart again. I had to leave the yard and get my backup blower. Any ideas?
Thank you for the info mine has ran great for the past 2 years but now it’s bogging down at full throttle after 5 minutes of usage I changed the coil with a oem and it’s still bogging down at full throttle it has new plug new fuel filter air filter and nothing still doing the same thing I’m wondering if it can be my carb let me know if you have any ideas I would greatly appreciated it 👍
@@wallysworkin823 Thank you I finally figured out the problem the new carb I installed was defective and it was a brand new carb but it happens once in a while you will receive a defective carb.
Great video Do u prefer the the walboro fuel filter with felt or u like the one that’s like ceramic Maybe future u can make video on ur favorite fuel lines and fuel filter if u had to put on back ur self
Wally, This is a great video. I have a PB-770T which has been running fine. Last fall it started losing power and stalling after 20 minutes of running like it was out of gas. I have to wait about an hour before it will start and run fine for another 20 minutes. Vapor lock or engine overheating. I read someplace that carbon buildup blocking the exhaust port. Any suggestions? thanks, Joe Desiderio
I’m working on a friends blower that won’t engage the plastic pawls when you pull the rope. I removed the starter recoil assembly and it works fine but I noticed a chunk of plastic broken off that looks like it should engage the pawls. I’m guessing it’s going to need whole new starter assembly to fix the problem unless there is a fix that I’m not aware of. (770 T)
My issue ended up being that my friend had attempted to fix his blower but put the starter assembly on crooked and it destroyed the plastic part inside. If your plastic pawls are in good shape you should be good to just replace the starter assembly. Just make sure everything goes back together correctly and the screws tighten down evenly.
Im not sure if you will reply. I have a pb770t just put a new carb on it. However, after just a few minutes, it boggs down, but idles fine. I've tried to find a sweet spot with the needle, but that doesn't seem to fix the problem. Any suggestions?
Start with the basics, good fuel, make sure the fuel line and filter are ok, make sure the exhaust port is clean. Are you adjusting the “H” or high side of the carb at full throttle?
I just picked up a used PB 770H, and my kill switch isn't working. I have continuity all the way to the coil so the wire and post are good. Blower runs fine though. Any thoughts?
Echo kill switches are terrible. You can try cleaning the switch with carb cleaner or brake parts cleaner. In rare cases the kill switch post on the coil itself will fail requiring a coil replacement.
I don’t like the carbs, I rarely see issues with the factory walbro. Rebuilding them will usually take care of any issues (walbro K23-WYK kit). I don’t have any experience with the top end kits for the 770’s. The ones I’ve seen for other units didn’t seem to last long or run properly. If I remember correctly the Echo piston kit is only $38 and the cylinder is $60 I believe, can’t remember exactly.
@@wallysworkin823 Thank you very much for your timely reply. I live in Tucson and use both of my blowers for Archeological work. I started using a compressor to blow off features and to find them. Then the blower was invented and I've been using it ever since. One thing to pass along. The blue foam air filters I have found leaking at the folded/pleaded ends of the filter paper. Candeling them using the sun, you might see tiny to large gaps of sunlight shining through. I doubt they do this during quality control. Not sealed well. l use silicone on those ends.
Having an issue w my 770t bogging down and stalling after about a 1/2hr on full throttle, but it idles great. I replaced the spark plug and put in brand new fuel. Possible spark arrestor or coil issue? Any help is appreciated. Thanks
Always check the basics first, air filter, fuel filter and exhaust. If it suddenly dies (like turning it off with the kill switch) when it gets warm it’s a possible coil issue. If it slowly loses power then it’s usually a fuel issue. It could be a simple carb adjustment but check the basics first. Check your fuel line as well to make sure it’s not leaking or has cracks.
@@wallysworkin823 thanks for your reply. I’ve done all the basics. The machine has maybe 20hrs total. It bogs down quick and dies. Restarts easy, idles great. Everything looks brand new. Leaning toward faulty coil.
@@patmk A coil will not cause a bog issue. Do you use it for home use? Has the unit been sitting? It only takes a few weeks of non use to make the diaphragm in the carb stiff causing the problem you have.
Start with the basics. Did you verify the compression with a gauge or just feel? I ask this because an engine may "feel" like it has compression but if it's not high enough it will be hard to start or won't start at all. Did you verify it has spark? A simple way is to remove the plug from the head insert it into the coil wire, ground the plug to the head and pull the starter while watching the plug for spark.
@@wallysworkin823 I have a compression gauge which I will check I only checked it by Buy fill and the spark I checked with a light that you buy from harbor freight to check this part and I tried spraying a gas mixture into the carburetor to see if it would fire Thank you very much for the reply really appreciate it and I will try the compression test and see what happens there Could you tell me what it's supposed to test at.
Great video! I've had mine 10 years now. No problems so far, just regular maintenance. (knocking wood)
If it’s 10 years old you’re doing great, no need to worry. Keep up the maintenance!

Could be the carb or simple adjustment. Make sure you have good fuel. Pull the muffler off and inspect the exhaust port for carbon.

What backpack blower do you recommend buying.
Need lightweight and powerful.
Don’t like the big blowers too heavy.
Find a Stihl dealer and try a BR200 or BR450. Also a Redmax EBZ5150 is an option.
Hi, may I know why as soon as I put my blower on high speed it shout down... Lost power and the power go off... Thanks in advance
Great video
Do u prefer the the walboro fuel filter with felt or u like the one that’s like ceramic

Hey frnds: behind the plastic air cleaner bracked is a hidden foam pre-filter. That's the first thing to chk!
Any clue why my sprak plug gets cloggged? Could it be not gapped correctly? Fuel mix? Has correct ngk plug so just wondering any input
Blower doesn’t want to accelerate and bogs down but once i pull plug and clean in between it it works just fine
What is your opinion on the Chinese knockoff carburetor/ cylinder and piston as replacement to OEM. Thanks ahead of time.

Sounds like Carburator problem
See if it does it with the gas cap loose enough to vent.
The shroud on Echo blowers is just cheap! They really need to up their game on plastics.
Sure, if you abuse the f out of your equipment everything breaks.. that thing looked like it was thrown everywhere.
Everything that comes in looks like this or worse. They run 7 days a week in most cases. Guy’s are hard on equipment out here.
