My name is Bre. I took two years of small engine repair at the local college. When I left school, I fell into a wonderful job at a local small engine shop where I worked the counter for a couple years. In 2010 my husband and I opened up our own small engine shop in central Arkansas where I am able to work alongside my family and best friends. We see over 2,000 pieces of small engine equipment every year, and answer 1,000's of small engine questions. We specialize in brands such as Briggs and Stratton, Kohler, Echo and Shindaiwa, but work everyday on MANY other brands like Stihl, Husqvarna, Honda, Craftsman, Remington, Red Max, Troy Bilt, Scag, Bad Boy, Hustler, World Lawn, Poulan, Mantis, Etc.. Hopefully, my experience I share, will save you Time, Money and Frustration in the future!

    I would love a full list of every tool you use as a small machines mechanic. Will be a great kit bag for our technicians. 😊
  • @jerryarmand
    OK! So You are the only "small engine" specialist I now have in my computer that I feel confident in going to for advice and help. I just feel that there's no BS when I watch your channel. You say it the way it is and every time I've done it your way it's been right. So Thank You for sharing your thoughts and knowledge on this channel and I will continue to follow you so I can get it right the first time.

    Been running saws for 30 years, this was the best adjusting carb tutorial I ever saw!!! THANKS!!!!
  • Hands down the BEST carb tuning video I have seen since YOUTUBE began. Thank you for sharing your knowledge. Be proud, you are awesome. 😊
  • I was cutting firewood commercially years ago and bought a new Husky 266 pro saw and ran a 28-inch bar. It was the best saw I ever ran. I must have cut 500 Coard of wood with saw and it never let me down. It would cut circles around any other saw in its class. Carb had to be adjusted every time I went out some days I would be at near sea level and other times I would be at 8000 ft. above sea level. I always set the high speed until the saw would just start to four stroke at wide open then adjust to get a clean idle and then recheck high speed again. When I buried that 28" bar in a log she cleaned up and ran like bat out of H. I own a boat and motor repair shop and have been adjusting two stroke carbs for more than fifty years now mostly by ear. My customers use their boat motors here CA. anywhere from sea level to 9000 feet and I have no complaints or come backs. I like and enjoy your videos most stuff I already know but you have taught this old guy a thing or two. Thank you
  • @billynair
    im glad i clicked on this one before messing with the carburetor!! My idle was high and chain was spinning (could cut 3-4 inches into a log in idle) All the other videos kept saying my clutch was going out (no, brand spanking new, never seen gas before) others said the low end carb screw needed to be adjusted. She said to adjust the idle screw, and that was it!! no messing with the carb, nice!!
  • @patthesoundguy
    I so agree with all of this. The question to ask yourself is when you want to adjust the carb is why... If it ran right last time and all you did was leave it sit, the carb didn't adjust it self so something has to have changed and Chickanic gives the reasons. That being said I every day carry the Poulan carb tool in my small belt tool pouch. 😉
  • @Herbybandit
    I've always tuned by ear just the way you showed with the tacho, it's important to keep in mind that if you must make an adjustment keep on the rich side as lean mix means high fuel burn temp which equates to melted piston and huge bill.
  • Ha, ha!!! "Honey-hole"! I never heard of that one before! Great channel.
  • @Krankie_V
    I really like the in depth explanation of everything. I've always done it by ear and while that has worked for me, I don't do this for a living. If I were doing it for a bunch of other people, I'd want to get the tacho and do it the official way for sure. You did a great job explaining everything. Nicely done.
  • @GoCoyote
    You have some of the best explanations and information I have ever come across for small engine equipment. Great work, and a great channel name!
  • @lynnbultman1679
    Great Video. Your procedure to adjust the 2 cycle carbs was great and well received. I own a farm property with several 2 cycle engines that occasionally require adjustment. This will make life easier. Thanks
  • @ashwilliams4989
    This is the most professional tutorial for proper carburetor adjustment of a two-stroke engine in a chainsaw ever found on the Internet. Even at my local Husqvarna service center, they wouldn't put that kind of effort into their work. These slackers set the carburetors on customers' chainsaws "by ear".... While setting slow revs by ear (L screw) will not harm the engine, setting high revs by ear (H screw) risks seizing the engine by exceeding the safe speed (e.g. 13000 rpm on most Husqvarna saws), at best they will set the high revs too low (e.g. 11000 or 12000 instead of 13000 rpm) and the saw will be less efficient. Thanks for your work. Greetings from Poland.
  • @BigRagufromAT
    I really appreciate this channel. I have been a pro carver for 33 years and I am always learning new things on YouTube. Thanks for sharing!
  • @cobbleup
    Great video!! I’ve been messing around with old 2 stroke tools for over 50 years and it was always a guessing game. Thanks for clarifying ❤
  • @6rowlettes
    Another great video. I love how you explain your troubleshooting and adjustment processes. Thanks for running through the different types of manufacturers and carburetors. Definitely going to purchase an engine tachometer after watching this video (sorry honey, just one more tool....).
  • Thank you for this awesome and very informative video. You are a GREAT teacher! You explain things in a way so it is easy to understand and learn from. This is clearly the BEST chainsaw tuning video out there! I have a FarmerTec Holzfforma MS660 Stihl Clone that has been very difficult to tune. I think I will finally get it dialed in after watching your video. Again, thank you!
  • @andybecker2693
    Your advice on finding the “root cause” on why your carb might need adjusted is the best I’ve heard. Like you said most people are trying to tune around an issue. When you buy from a dealer they will tune it for you from new and after it breaks in if needed. Yet another reason to support a local dealer.
  • @bagadonutz5717
    Just watched this and my old kombi trimmer is purring again after a couple tweaks of the carb & a new gasket. I was all set to replace the carb but was lucky to have found this clip You’re in my top books 👍🏼
