* VISUALLY EXPLAINED by Craig Kirkman, a renowned you tube educator of these systems.
Very few people know this, but there is a very special Pump inside your Chainsaw Carburetor, and any malfunction of the pump and can cause a whole host of problems (bog, incorrect running and starting issues, to name just some). Powered by the fuel pump diaphragm, this pump is the heart of the 2 stroke chainsaw carburetor.
My Chainsaw was Bogging down when throttled and not Idling correctly. I Easily adjusted my Carburetor without any cost. You can to. HERE'S HOW I DID IT.

Here I have some useful information for you if you need to tune the carburetor on your chainsaw. Anyone who has tried this for the first time can tell you that it's quite a daunting task.
If you have tried this yourself I'm sure you will have thought, where are the adjustment screws exactly? Even if you know where they are you might then wonder, which screw do I adjust? If you know which screws to adjust then, which screw first? How much to I adjust them? Do I turn them inwards (clockwise) or outwards (anticlockwise). After trying to adjust these without any experience it can result in complete frustration. What I hear a lot is "my chainsaw wont start"

Anyone who has experience tuning chainsaws knows, whether it be a Stihl chainsaw, a Homelite chainsaw, Poulan, McCulloch, Jonesered or husqvarna chainsaw, that there are so many different types of adjustment screw heads on all of the different brands available. Some have screw driver heads and others have specialist tool requirements. Here I have included a great adjustment kit on Amazon, which will fit most chainsaws: https://amzn.to/39EbJg0
Thank you for viewing this video where i show you how I personally tune a chainsaw. Thus will help get your chainsaw running well again and prevent chainsaw "BOG" or "BOG Down" as some describe it.
Some Chainsaw adjustments don't have the conventional screw driver shaped slots on the adjustment screws. Instead, they have splines and pack-man shaped adjustments and many more.
Please take this advice as demonstration purposes only. It is your very own decision whether or not to take this advice and any undertaking relating to this video, by you, must be done so in the correct safe manor as dictated by your safety user manual. Do not undertake any of the procedures shown in this video unless you are sure of your own safety as described by your safety manual.
Although this video is focused on running Chainsaw running problems that can be rectified by adjusting the carburetor fuel adjuster screws, it can apply to mostly any 2 Stroke engine. That's because the two stroke engine fitted to most small garden machines are pretty much the same principally.
Thank you
