    Thanks Steve. I was able to get a set of carb adjustment screwdrivers on amazon for $9.99.
    I have a Poulan I’m working on and now I know how to adjust the carb more accurately.
    Thanks for the time you put into your channel and videos, keep up the good work!

    Excellent video Steve. In the process of doing it today to an older 16 inch McCullough. Just rebuilt the carb completely and ready to set it up. Thanks for the video Steve 👍👍👍

    Good information, thanks a bunch! Subbed and liked, learned something today 🙂
    If I may ask: On the low speed screw, when you hit the sweetspot, why do you turn it out again, why do you want to have the lowest speed not as fast as your fastest lowest speed. Your fastest lowest speed… Does that even make sense? lol 😀

    Thanks to watching your video's I fixed my own broken leaf blower. It needed two new brushes. It runs like the day I bought it, 30 years old. OLD Weed Eater brand. It sounds like a jet air plane but it blows leaves pretty dang good.

    Steve, on a Stihl MS290 chain saw the plastic plugs on the L an H adjustment on the carb, can I use a pick to get out to adjust the carb?😃

    Steve, Video idea… Any specific tips on how to straighten a bar that's been stepped on or otherwise bent or twisted? How straight does straight need to be?

    The only problem I have is that I the required screwdriver is so small I keep misplacing them in the general to & fro of tree & firewood cutting sessions!

    My saw starts and the idle seems to be great however upon using the saw for cutting it seems to get too hot? It will shut down and not restart until it cools down again. I am leaning towards a carburetor adjustment of the fuel to air ratio thinking it is too lean. What do you think? Husqvarna 375XP

    Hello Steve. I have a Stihl 025C. It has a primer button. It turns over after several pulls but immediately dies. Took it to Stihl and they said it could be the carburetor or fuel line. I tried to take the carburetor off but don't know how to take the primer hose off. And not sure how to tell if the carburetor is bad. I also tried to adjust the idle (LA) and turned right all the way till it would not turn anymore and my chain never moved. Any suggestions to get it to turn over and idle is appreciated.

    Best chainsaw tuning video out there. Many years ago I ordered a Stihl EDT 5 Tach, turned out one of the best investments I made for working on small engines.

    Steve, I am replacing the carb on a Echo CS 346 chain saw and the made in China 15 dollar kit has gaskets without the size and holes to slip over the locater projections located to hold the original gasket in place during assembly. What can I do to hold the new gasket or should I hope the old gasket won't leak when I reuse it ? Thanks for your videoes.

    Hey Steve. I used this video to tune up my old Stihl. Runs better and doesn't stall out at idle anymore. Still bogs a little when cutting a tree. The new carb has always be used with "designer" fuel, Husqavarna I think so it should not be clogged up.

    My saw never idled right from store but with your info it will idle all day now,thank you for all you do,a true Guru of small engine repair.

    Thanks Steve. That helped me with my new Stihl. I’m 70 yo and just can’t pull like I used to. If I can’t get it started, I ask my son to do it. It always starts for him. Guess it just needs more gusto on the string.

    What if my Stihl won't idle long enough to adjust? Is there a method to establish a baseline to start from? Like screw all in until stop & back out 4 turns… Something like that?
    Has new fuel, plug & filter. Idles for a couple seconds & dies.

    No talk about "4-stroking"? I thought It was a reliable way to set the high speed screw?

    Steve I enjoy all your videos, but I have a Stihl 250 that if I get it to run, it only runs for a few seconds(10 – 15 ) seconds then quits. I have tried everything. Any ideas ? Thanks Michigan
