Thank You!!! Finally an answer regarding which is which by rule. Closest to engine - Low. Finicky litle carburetors.. One minute in everything changes again.. I think this is important make small changes one per minute.
First video I found that actually says which direction is lean and rich. Most other videos: "HERE IS THE BEST WAY, YOU GOTTA BUY THIS TOOL, FIDDLE WITH IT UNTIL IT SOUNDS RIGHT, LIKE AND SUBSCRIBE!!!" Very good video, thanks!
A good starting place is about 1 turn out (for almost all machines). Thinking in terms of worst case, consider that a too far out screw is too rich and therefore fouls the plug, so one could always start too far in (too lean). Pull and pull and pull on the starter rope but slowly back the screw out 1/8 turn at a time until it starts...that gives you your "absolute most lean" condition under which the engine will start, then make it richer from there. On the H screw, you can again start very lean (all the way in) and just snap the throttle quickly. When too lean, it will stall but you can again back it off in 1/8 increments and "see and feel" the difference the mixture makes with each throttle snap....hope that makes sense!
Do you have a tach for single cylinder engines? I'd like to know the idle RPM and full running RPM once you set at the sweet spot. Thanks for your time/video!
It might have to do with the tuning of the carb but also remember that blowers are always “under 100% load” whereas chainsaws, string trimmers, etc have no load until they come into contact with wood, grass, etc. blowers never “make contact”. Hope that makes sense…
Wow never knew this. I also wonder that. Thanks for him to ask and you to answer his question… I’ve got a 150bt the carb is the issue. I only see an idle screw and what I think is a high screw..? Not really sure. And noticed all the replacement carbs are the little red choke tabs and not the blue pull choke tabs will the red choke carb work on that he newer versions…?

Best explanation Ive heard yet
Thanks so much!!
your description for the blower was awesome...wish we hadn't taken a side trip into the saw though...but otherwise amazing.
Glad it was helpful. Fair point!

You’re welcome!!

Very good video, thanks!
You’re welcome, and thank you for the feedback. I decided I would never ever ask for like or subscribe. I hate being asked by others.
Very good video.. very clear and understanding the tool.... thanks.. it helped me adjust to the right tune on my husqvarna 125b after a muffler mod.
You’re welcome!!
What muffler mod did you do!?
Wow, you are great at explaining...
Thank you!
Glad it was helpful!
Outstanding presentation. Thank you!👍🏻🇺🇸
Glad you enjoyed it
My guy! 👍👍👍

Great info ! To tune the carb , what is a good starting place to open your Hi and Low screws at from fully seated , on that blower ?
A good starting place is about 1 turn out (for almost all machines).

Yes, I do, I actually just uploaded a new short video to TH-cam on my channel for you. Check it out and I hope it’s helpful.
Best video ever. You are natural. Very gifted 👍keep up the good work
Wow, thank you
Why do backpack gas leaf blowers sound quite like a 4 stroke?
