Oh man. I need to adjust my bg86. Mines boggy on initial throttle pull. Thanks for explaining and demonstrating what the low and high adjusters do. Awesome video.
@@jackle842000 that's what he said 😆 but I found it had a lot more power with the Echo oil. Red armor and power blend are both great even my trimmers run better.
My high and low speed adjusters are not Philips head it looks like a nut adjustment what tool do I need only my idle adjustment is a Phillips screw can I order it somewhere or just go to a Stihl dealer
I saw many specialty screwdrivers for these carburetors. Unfortunately, I could not find the exact tool you speak of. I found some that were CLOSE, but not quite. 🤷
I’m having the same problem trying to find the tool to adjust these L & H Carburetor screws on a HS56 hedge trimmer. Mine also isn’t a Philips or flat head screw slot, I need something like a socket. Not sure if hex or what size. Feel like stihl have purposely made it difficult to perform a simple carb adjustment.
What about the LA adjustment. I turned that and the low adjustment, and I don’t know how to get it perfect. High adjustment is normal, but it floods when I try to start it, and it runs terrible.
@@clemsonruggeryup. They make it a super thin walled socket. I assumed the 4mm one I got from Stihl to adjust the same style carburetor screws on my FS56 would work. It doesn’t. It seems to be either a 5 or 6mm thin walled socket.
Thanks, but I just replaced mine with new carb and I can't get it started. It was running poorly prior. What are the initial screw settings so that I can get it to run? I obviously can't warm it up to set the jets if it won't start to begin with.
Need compression and vibrant spark. So, check both of those. If yours is older though, it might be time to move on to a new one. They don't last forever.
@@HorsepowerHouse20 Had compression and spark prior to changing out carb. It started but ran funky and I figured a carb change might be a cheap quick fix.
@blenderbender The "starting to run funky" could be the motor is done, or spark plug, or coil, or plug wire, defective kill-switch, could be any number of things. Did you CHECK for compression and spark? My guess is no. These things rarely give warning. They just go when they decide to. Like I said, these little engines don't last forever. If it has alot of time on it - it's probably done.
@HorsepowerHouse20 I think he means an actual reference point it will actually "start" from. I just bought a new carb so I have that same question. Ty.
I bought a BG56 May 2024 and has a hex adjustment so purchased the 12 piece carb adjustment screwdriver set from Amazon and the 4M Hex that comes with that set will not work. The 4M Hex is correct as I referenced it with an 4M Alan wrench. You cannot purchase the wrench through Stihl so Im ordering a 6M deep socket from Amazon and will gring the wall thin to see if that fits.
I just found the Pac Man screwdrive works from the Amazon set. Its not the right screwdrive but it works. The 4M hex doesn't work, nor does the splined or the star screwdrivers. But the larger PacMan screwdriver will work.
Just got one from my father in law. Run great now. Thanks to you. ^^

Thank very much
I got my bg56 2 days ago it's awesome
Yeah it's pretty decent for a hand blower. I like to run Echo power blend oil the carbon buildup is almost very little.
I feel like this model doesn't blow near hard enough.

Thanks for sharing, hope these tips help me fix my stihl. Same as you have.

I'm with the same issue. It's like a hexagonal prism, but doesn't have the space for a common tube
Stihl changed it often.
I change the carburetor, the new one has for common screwdriver
NICE VID HELPFUL THANKS
Great video 🤜🏼🤛🏼
Cool! Thank you for this!

if it has always run poorly, you have bigger issues than some "adjustment". Sorry, bud.
Thanks a million, sir, excellent video
You didn't show removing the limiter caps. Can't do adjustment till those are removed
Because mine has none. never did. Bought it brand new as you see.
@@HorsepowerHouse20 I examined mine. The 'limiter' caps are now part of the carb body. Crap. It takes an octagonal socket.
you can get it on Amazon.

Is that half turn from being all the way in so open half turn?
Very helpful, thanks bro

Did you check compression of the cylinder? These tiny engines don't live forever.

@@HorsepowerHouse20 Thanks.... I'll look into it further.
High speed adjustment screw was key : )
I have the SH 86C and it doesn’t rev very fast. Weaker than my battery powered blower.
Tune it up and service it then. Very easy.
Check spark arrestor it may be clogged with carbon
I have a SH 86C. A Phillips doesn’t work. Do you know what screwdriver will fit? Thanks
Works on mine. As shown in the video.
@@HorsepowerHouse20 I took the cover off mine and no phillips only phillips down the bottom
@@robwerner5559the newer models have a thin walled socket you need to adjust the screws. It’s really frustrating.
I have a new one and it runs badly..
Take it back to the store.
About how many turns out are your screws so I have a reference place to start?
It only has 1 turn. Set it to when it runs right.
