Hi guys I just wanted to Introduce to you my other Channel "Things to Know" - which i'm just getting started. It's a go-to channel for insightful worldly explanations, handy tips, and expert advice on everyday things and repairs of domestic items.

👍👍👍👍 10,000 Times from all of us who are in the BUSH and have a new C S and no knowledge of how to adjust a chainsaw. There are many good videos, but the close-up views is the BEST .May our CREATOR bless you.
FINALLY! I've been hoping to find your kind of material for a long time - explaining how to fix things by explaining how they work, so much better for me than just "hook the red tube to the brass nipple" type instructions. Thank you, I'll be watching many others I'm sure.
Outstanding!!! I knew how to adjust the carbs on my chainsaws, but as I was trying to teach my son I stumbled to try to explain it- I just didn't have the right words. Thx to several of your videos I was able to sit him down to watch it and He and I have a whole new understanding of the process. Thx for your time !!
This guy is total amazing... This video goes into so much depth explaining everything there is about chainsaw carburetors... I wish I could find a video like this one on riding mower carburetors. Thank you for all the time you put into creating this video..
Yes Sir ! You did it again ! Another great, very detailed video that will be easy for anyone to understand. Thanks for sharing and keep up the great work my friend.
Craig, thanks again for your insight and tech explanations. Further to my earlier ( lengthy) comment, I have successfully tuned my Husqvarna 128ld string trimmer. I have no idea how many of your videos I've watched but consider them to be superior to all of the others on RUclips on this subject. I have one suggestion which may have negatively influenced my initial lack of success tuning my engine. I knew I ought to tune with the engine under load so was using my gas clipping blower. The horrible racket and vibration obviously indicated that there was something wrong with it, Rather than continue to mess around with it, I withdrew to my trimmer attachment and within a very short while my engine purred like new. Maybe that will help someone else. Thanks again. Dave in Houston
What an informative video! My whole life small engines in the likes of a weed wacker or blower have always stumped me. Eventually they fail and I'm left debating a repair cost or buying new. This video will play a role in my education on engine repair. thanks!
Hello from Detroit Michigan brother thank you for sharing your knowledge and expertise it will really help me out with my project thank you so much for the information
An absolutely perfect explanation of the true purpose of the Hi and Lo needle valves! I probably witnessed the smallest insect on camera... @ 8:48 there is a bug checking out your metering pin area in the carb 😁
I agree with you in that understanding the functionality of components within a system helps one troubleshoot and repair it immensely. Thanks for the informative video
Thank You For The Best Explanation I've Ever Seen & Heard & I'm Going To Share With All 3 Of My Son's & Several Friends & I'm So Glad I Found You & Your Fantastic Videos, ☆☆☆☆☆ , 👍👍👍👍👍
Thank you sir, for this detailed explanation. U are a master teacher, I keep looking at your videos over an over. U have help me alot, . may god bless you always. From Trinidad.
Good morning, your videos are very helpful and educational so thanks a lot for sharing! However I do have a question, in which sequence do I have to adjust de carburator? First H, then L and subsequently the T? Thanks a lot for your response! Regards Bart
I fly a paramotor. Its a 2 stroke engine with a wb 32 walbro carb its not been running right then I noticed there is a spacer that is supposed to go between the carb and engine. I put it back on and it made it very very lean it would not run at all and needed around quarter turn rich on low end. Any idea why this would be . Why or how does an extra spacer between the carb and engine make such a large difference
Does anyone have any ideas why my husky k760 looses power mid Rev when I’m cutting? It seems to happen when I tilt the saw to cut. There’s plenty of fuel and it’s in otherwise good condition
Hello Good day, I just like to ask on what is the proper way I need to do in my chainsaw after i USED and it will be stock for a six month before I used it again
I've found that the adjustment of the L screw also affects how quickly the engine responds from idle. There is a happy place in this adjustment. I really appreciate your drawings/animations. They have cleared so much up. I'm presently flummoxed by a 028 Stihl Wood Boss saw. With the spark plug out of the engine, I get good spark. With it in, it behaves as if there isn't any spark. The plug comes out wet, every time. The plug is new, as is the coil. The flywheel is where it is supposed to be. What gives?
good video but beyond the average bloke? what they dont tell you is which screw is which? early ZAMA threads are same size BUT needle ends are not the same! A big help would be a comparison of low and high screws side by side ,so they cannot be screwed back in wrong holes ?
Do you have an easy explanation regarding why a lean state during high rev's causes the engine to run at higher rpm? Intuitively I would have thought that if there wasn't much fuel around, the rpm's would drop. That doesn't happen, but I don't understand why.
@@TheRepairSpecialist Yes, that's helpful, thank you Craig. More efficient when lean but because lubrication comes from the mixed fuel, there is a compromise to prolong engine life.
If they are not different lengths or thickness then it most probably doen't matter which one is which and either will be ok in either hole. Some are designed like this, but take a very close and thorough look to distinguish the sizes first, then if you are happy they are the same size then you can decide, or not, to just fit them in either hole. I hope this helped Craig
Hello guys! Can someone help me? Do the adjustment screws have to be airtight? I have an air leak issue with my chainsaw. I already checked everything, but I can't find the leak. Thank you!
Hello! Of course, we're here to help. When it comes to carburetor adjustment screws on a chainsaw, they don't need to be airtight themselves. However, the carburetor as a whole should be airtight to ensure proper engine performance. If you suspect an air leak in your chainsaw, it's essential to address it promptly because air leaks can lead to poor engine performance, including difficulty starting, idling issues, and loss of power. Here's what you can do to track down and resolve the air leak: Inspect Gaskets and Seals: Check the gaskets and seals between the carburetor, intake manifold, and engine block. If any of these are damaged or worn, they can create an air leak. Replace any faulty gaskets or seals. Tighten Fasteners: Ensure that all screws, nuts, and bolts on the chainsaw's engine and carburetor are properly tightened. Loose fasteners can contribute to air leaks. Check Fuel Lines: Examine the fuel lines for cracks, splits, or loose connections. Any damage to the fuel lines can introduce air into the system. Replace damaged fuel lines as needed. Inspect the Intake Boot: The intake boot connects the carburetor to the engine. Make sure it's in good condition and securely attached to both the carburetor and the engine. Use a Carburetor Cleaner: With the engine running, you can carefully spray a carburetor cleaner or a flammable aerosol like starting fluid around potential air leak areas (carburetor joints, gaskets, seals). If there's an air leak, the engine's RPM may briefly change when the cleaner is sucked into the leak. Professional Inspection: If you've checked all these areas and still can't locate the air leak, or if the issue persists, it's a good idea to have a professional technician inspect your chainsaw. They have the expertise and tools to diagnose and address more complex air leak problems. Remember, addressing air leaks is crucial for the proper functioning and longevity of your chainsaw's engine. We hope this information helps you pinpoint and resolve the issue. If you have any more questions or need further assistance, please feel free to ask. Thanks Craig
Hi Thanks for a great video, quick question, as a rule does the low screw always let fuel into the carburettor on the outlet side of the venture? Many thanks David
Hi David. First of all, thank you for your kind words, i really do appreciate it. Secondly, yes, from my own experience with carburetors anyway, the L (LOW) Screw is always on the outlet side, and so the closest of the two adjuster screws to the carbs outlet to the engine. Thanks again Carig
Hi Craig, thank you for giving me a great understanding of how a carburettor works, with the knowledge you given me I’ve traced the issue back to the hole at feeds the High rev adjustment being blocked with a piece of metal, (maybe the previous owner has over tightened the adjustment screw and snapped the end off ?) unfortunately it’s jammed so it looks like I need a new carburettor. 😢
These screws are the worst design ever. I have one on my motorcycle Mikuni carb, on the bottom where you can't get a screwdriver in anywhere. Tweaking it clockwise or counterclockwise really doesn't give you a lot of feedback while it's running if your rich or lean. I just try to get it where it won't stall out when you twist the throttle. The real, real, real problem is the Pilot jet, which has the smallest hole ever in the center and gets clogged all the time on my bike, even with a fuel filter on, and even with a surgically clean carb. Worst... design.. ever.
Sorry to hear that. At the time of making the vid I thought those sounds would give some extra meaning but I think I must have overdone it somewhat. Thanks for the feedback.
@@TheRepairSpecialist They sound great to me. I heard you speaking over the sounds clearly and the sound does a good job of highlighting a crucial part of carb tuning, and that is the sound of the engine.

Hello
Good day, I just like to ask on
what is the proper way I need to do in my chainsaw after i USED and it will be stock for a six month before I used it again
what about the idle screw? when tuning a carb. do I need to back the idle m screw out til it's barly budging the arm?
Hy there sir..my makita chainsaw is at high speed then die out what is the problem..without pressing the speed
Can you rotate the fuel inlet nipple to align to fuel tank ?
I've found that the adjustment of the L screw also affects how quickly the engine responds from idle. There is a happy place in this adjustment.
I really appreciate your drawings/animations. They have cleared so much up.
I'm presently flummoxed by a 028 Stihl Wood Boss saw. With the spark plug out of the engine, I get good spark. With it in, it behaves as if there isn't any spark. The plug comes out wet, every time. The plug is new, as is the coil. The flywheel is where it is supposed to be. What gives?
