I'd definitely keep it original. A blower like this deserves to keep it's original parts

I would buy the rebuilt kit for the carburetor drop it in a ultrasonic cleaner and call it the day. 👍🙏👍🙏

If it was mine, I'd go with a carb kit. Machines like that deserve to be kept as original as possible.

Thank you bro I saved myself several dollars . Your videos are educational . I had trouble with my blower and you should me how to clean the lines . Thank you Sir . Have a blessed day 😊

Since you already have the rejuvenator, you have nothing to lose by trying it first. It might save you time and money waiting for the new parts to arrive. If it doesn’t work, then order the parts. I usually try to work with what I have on hand first.

My grandfather has a Stihl bg72 from 1990 will always start with one or two pulls

Never seen an echo like that one so a first for me and in decent shape

That echo pb 400e is one of the best toughest, hard to kill blowers in echo history. In fact the one i have is a pb9 which has gas tank on top of unit and a float carb, it is from 1970 and it later evolved into the blower you have, great share, thank you.

Years ago when I was doing lawn care a customer had one of these blowers that I had to get running every year. Seems like it was gray but it's been a long time. It was old when I started working on it and I got it running but never used it. We either had the Echo handheld jobs or the Stihl backpacks. And I had to fool with it too so don't feel bad. That was just the way they were. BLESSINGS!

I'd definitely do what your doing,at least you know you saved all the $you can

I did a little bit of adjustment on the carb on my weed eater and now the engine is running great and it's not smoking anymore and it's not using much gas😁

O hell yeah i would investigate the problem more. Its not even the small amount of money. It's the new remedy you may find that will help you on the next one. Great vid. Cherrs mate.

well for me if that was my backpack leaf blower i,d simply take it step by step to figure out what is the goer or situation with it and to your video giving me a good idea it has a excellent amount of compression and a healthy spark so don,t give up on it that easily as it could be a fuel line or a fuel filter issue as they tend to clog up from time to time and they are often easy fixes too etc.

After many days of f'ing around, I discovered my zama carb had MANY check valves inside. These check valves sticking open or shut is what stops them from running. It is why "rebuilding" them and "cleaning" them don't work. I was crazy enough to rehabilitate these valves and was successful at that on all but the check valve on the main jet. Not sure how to remove that one. I ended up getting an aftermarket carb. But the catch is they are not the same. My OEM one had an accelerator pump for instaneous throttle response. So now I live with some bogging when I throttle up. RIP

I would get an OEM carburetor for any name brand lawn equipment. I love the older blowers they seem to have better quality than the newer ones do

To answer your question: I´d never even think about buing an aftermarket carb anymore. If cleaning the original carb manually and with the ultrasonic cleaner and installing an oem carb kit doesn´t help I´d get a good used oem carb and try again with the same method. Aftermarket carbs gave me a lot of trouble, I learned my lesson the hard way. With some of them the engine runs like a sack of nuts, no matter what you do to them. Some run the engine surprisingly fine but I don´t know what material they are made of, some deteriorate already after a fiew months from the fuel or the elements. Rubber parts and gaskets swell up or shrink and cause failure. No. I´m through with aftermarket carbs, in my opinion they cause nothing but trouble.

❤️❤️❤️ loved the video

Check the cranckshaft seals too

Since I still work and do not have much spare time, I'd probably buy a new carb. When I retire instead of watching TV I would probably spend all day on the mower trying to fix it.

That looks like a early 1980,s to late 70 ,s model of back pack blower

God video tanks for sharing

What do you soak the diaphragms in to bring them back?

I'm curious about what you use to rejuvenate the diaphragm.

I guess that depends on how much time you have on your hands. Getting it working again for pretty much free with nothing but skill is probably worth some burnt up time too

Vintage is good. 1995 was a quality year for small engines. Go back 28 years in your life and the nostalgia might be overwhelming.

First try then go to second option $20 on own equipment but if doing a friends then $20.😊

I would put a carb kit in it.

Shindaiwa and Green Machine uses the same design. But Echo is probably the only ones that might have hard parts for it.

I ran the super xl running good check it out

Putting gas in the cylinder vs quirting gas into the carb. I'm confused. Wouldn't squirting gas into the carb actually indicate if the carb is working more than squirting into the cylinder?

I've seen kodibass he uses Vaseline on the rubber parts to help someone them

I have 2 or 3 of those that might be a little older, air filter box is a little different. I would have thrown a carb kit in it and that usually works. Hows the fuel pickup/filter? Line have a pinhole?

If I am going to work on something I prefer to fix it using the current parts. If that does not work then purchase the needed parts and move on. I don't do this for money so time is not an issue for me.

I would of done what you done then if it didn’t start, like I the video, I would order a kit.

New carb

New carb.

I did every thing u did ended up buying a carb.btw spray carb cleaner in the carb,starts easy that way..

Its usually the diaphragm that goes bad over the years on these 2 cycle carbs.

how was the spark plug...what was the initial complaint? ....not a biggie since it started....prob new carb....ALL new parts ....customer dont want 1 old part fixed with a new part working with a bunch of old parts ready to break

What oil do you use for your mix? And what would be the best I want my machines to run as long as possible

🥰

Where are the screws located on a 4-stroke carb like on a honda gx25?

Did you check the fuel filter? May not be letting enough fuel past. Cheers

I am working on an Echo cs3900 . They are ok but not as good as Husqvarna

I have a older version of yours. I went with an aftermarket carb as the one it had was very finicky even after adjusting and cleaning. Did you use 50:1 fuel? The manual is quiet confusing at it mentions 32:1 and 50:1

Yes save the diaphragm if possible

the fuel pump

I would’ve bought a $20 carburetor

Aftermarket carb is $15.00 ish

20 on a new carburetor

....low speed screw is always closest to the engine.....also, diaphragm is crusty

So I had a chainsaw and I would think it was going to be an easy fix but I would not get any fire. So the. I put some fuel in the spark plug hole and it still wouldn’t fire……. I forgot to turn it on

20 bucks? I would just go for the carb if the customer was paying for it. If it was mine I would try to rejuv the diaphram
