I was ready to go out of town, and my new blower went on limp mode, you save my bacon with this video, I only used 4 little oil bottles seems to soon yo have this issue. Thanks a lot. It worked like new.
Glad to hear you got it going. Such a common problem with these blowers, I try to switch people to Amsoil Saber 80:1 or 100:1, seems to solve the problem.
I just want to thank you. I did exactly what you said and took the spark arrestor out, torched it, wire brushed it, re assembled it, fired it up, and it ran like new! So simple, but I wouldn’t have known that if I hadn’t found your video. 👍
No way man! Tried this and i cant believe how easy it was! I had a magnet and used a flathead. My lawnmower store near me chates $70 just to look at your machines!!! U probably saved me over $200 !! Thanks man!! Much love keep posting
You rock! I was in the middle of my fall clean up and my Stihl BR 450 started to not go to full power. It is several years old and has never been serviced, and I feared the worst, especially since my local power equipment company has an 8 week backlog on repairs. Your suggestion did the trick and the blower is back at full power. I will be taking your advice on the oil, as I have only used the Stihl brand to date. Thank you!
I got a 6 pack of the Stihl oil to double my warranty back in 2011 when I bought my BG86CE handheld blower. The spark arrestor jammed up in the first year when I was using up all that Stihl oil. I switched over to the Husqvarna synthetic and I haven't had a problem with it in the last 11 years. I did have to replace the starter rope and the primer bulb but it still has the original spark plug and carburetor gaskets.
There ya go! There's seems to be something in that Ultra oil that plugs up spark arrestors. Don't know what it is. Some people have good luck with it, some use the Still HP with good results, some use the Amsoil Saber or Dominator 2 Stroke.
Short duration runs doesn't help either. I was running a lawn route back then so I was using it for a very short time about 30-40 times a week. @@fischertoolandgarden
Stihl regular 2 stroke oil worked perfectly well for decades. 50:1 with good gasoline. Don't run old gas. Dump the crap in your pickup truck. Your truck will never know the difference. The synthetic push is an EPA thing.
I agree. If I was to only choose Stihl Ultra or Stihl HP, I would choose the later, but I still like the results of the Amsoil Saber. Good Fresh gas is the key probably for all of it.
@allbayfishing9456 I really don't think the spark arrestor has anything to do with the EPA. When I was part of a family business in the midwest. Those California screens mysteriously vanished. Just like magic.
Sometimes the fuel filter needs to be replaced especially in backpack blowers. I'm thinking it might be a fuel starvation problem, hard to tell. Other than that it might need a carburetor adjustment or replacement. Hope you can resolve the issue.
My issue on my br400 is that the tab on the thumb side throttle lever snapped off. I have the new part. But, cannot compress the washers enough to install it. Any suggestions?
Been a long time since I've worked on one of those, but I believe I made a tool for that. I found a piece of pipe that was about the size of the outside washer diameter. I cut a notch in the end big enough to slide the clip in. Put the left handle, washers, and bolt in a vice, compressed it, then snapped the clip in place.
I see those come in clogged up and I almost always find poor quality fuel in the tank. I think some people put too much oil in the fuel thinking it helps (spoiler alert: It Doesn't). If you just run the motomix fuel this problem will never happen in the first place.
Yes Motomix is a great fuel, 99% Alkylate, unlike others I've found except Aspen. This burns super clean. I had a customer come in yesterday that uses Motomix exclusively, no repairs or problems
Fuel filter, Air filter, Carburetor adjustment or replacement? If the fuel filter and air filter are OK, I would try to hold the throttle wide open and try adjusting the High needle (H) on the carburetor. If it doesn't work, and the blower has good compression, I would probably replace the carburetor. I would probably check the exhaust port and muffler first for any blockage though.
I don't think the Fire Department would like that, hah! I do think that you need a little backpressure from it for the machine to run properly, just like 2 strock motorcycles. Fully plugged is a bit too much.
Me personally. I don't put those back in. When I come across equipment I work on with that problem I just leave the stupid screen out. You'll even get more rpms without it
mine cranks up fine idle good throttle up fine for about 45 seconds then the power drops to nothing acts like staving for gas wait few seconds and runs okay then reoccuring problem /
hard to tell. Possibly a dirty fuel filter or the tank not venting. Definitely sounds like it could be a fuel line issue. Any other ideas on this thread welcome.
It's funny, some people are stuck on one oil and find it hard to try a different oil, especially if it's 100:1 or even 80:1. Most of the time when they try the Saber, they really like it, but some are afraid of the ratio. You can run the Amsoil at 50:1, but that makes ME nervous, too thick my clog the jets. I'm probably wrong, but that's my quirk.
@@fischertoolandgarden I always try to explain to people your mix ratio is reflective of the quality of oil you're not some intrinsic property of the machine but some people just refuse to understand.

Thank you for this video! Exactly the issue I’ve been having with my BR350. And will definitely start using AMS now
Good to hear!
This video saved me from buying a new blower tomorrow morning before my first cut a fat blunt and we fixing the problem
Great video, Thanks for helping us out!
Running smoothly
Thanks, glad we were able to help!
great video, cleaning the exhaust solved the issue perfectly, Thanks!!

Good stuff, I'd say the 350/430 and 600 are the best units
I Just Ditch That Screen Since I’m Not Using My Equipment In a National Forrest 😀 No More Issues
Is that what a lot of people do, just remove that screen ?
@@TADDs101yes. A shop can’t tell you that due to epa violation

Just saved me a trip to the repair shop! Thanks
Glad to help!
Damn, thanks man “WOW, this video just saved me 150 bucks” 😂 😆
We have done your solution in the past but now having the same problem and the filter is clean. What do we check next?

Thanks for sharing , this did the trick, you saved me $75 atleast👍👍
What if I did this and it is still not getting power to blow?

Do you need the spark arrestor? Can’t you just remove it

Great Video is right!! Thank you sir!

Check valve clearance.
My 600 did same thing
Did valve clearance job,runs like new
@@neal197 Yes BR 600, 700, and 800 4mix. This is a BR 350, no valves.
I take the fascia off and have that job done in a fraction of the time.
Yes, it could be faster that way, especially if you use a battery drill. Remove starter, then engine cover.
Stihl ultra is junk oil, only JASO FB rated amsoil, Echo Red Armor, and Husqvarna XP oil are all JASO FD rated and burn much cleaner
