    Mr. Todd M., I don't know what you do in the real world but I have never listened to a tutorial that was this comprehensive in it's content and intuitively sequenced. Every item addressed is followed thru until completed, and to my amazement you remain on the centerline of the ladder logic chain with no distractive narrative which aids you in articulating the topic in the most succinct manner I've heard on KZread. Tenured professors struggle to do what you do effortlessly. Cheers

    Thank you for this helpful video. Yesterday I picked up the same saw (an older model like yours with no fuel primer) and I'm having trouble starting it. It's very hard to pull the cord - but easy when plug is out. Cylinder & ring look good as inspected through the exhaust port. Your video was very informative and clear - I just learned so much about my first chainsaw!

    Glad it helped! Thanks for watching, and for the comment. Their big saws have a compression release on the cylinder. If you see that, push it in, prior to starting. It will pop back up, allowing the saw to create it's maximum compression, as soon as the engine fires (so if it fires and dies, you have to push in the compression release again, if you want it to be easy to pull start). If it's been sitting with fuel in it, even with the fuel tank empty, and having been run until it died, there is still enough fuel residue in the carburetor, to chemically cook and destroy, the soft parts in the carb. So either the fuel pump section of the carb will be non-functional, or the metering section will be non-functional, or the internal check valves will be stuck, or some combination of all 3. Either way, it won't start, or if it does, won't stay running, or run well. These are also prone to crack or break the fuel hose (as mentioned in the video) in the space between the lower fuel tank housing of the saw, and the upper engine housing. If this has happened, the saw won't start or run, because the carburetor is not able to pull fuel from the fuel tank. Same goes for the fuel hose rotting and breaking off inside the fuel tank, which is why in so many of my videos you see me inspect and smell the fuel tank, as one of the first diagnostic steps. If the fuel tank reeks and smells like pain thinner or turpentine, I know the carburetor is going to be in very bad condition. Remove the air filter, spray some TriFlow Lubricant down the carburetor, and attempt to start the saw. If it runs, you know the saw is probably a good running saw (probably) and that it's not getting fuel from the tank; either due to a dead carburetor, a non-functional impulse signal to the carb, or a failed fuel hose or clogged fuel filter. If the saw won't start on TriFlow, it either has low compression (regardless of what the piston and cylinder look like), or no spark due to a failed spark plug, or a failed coil. The best way to start these big saws (or any saw) is to turn it at an angle, and clamp the rear handle between the lower area of your thighs. Grab the curved part of the front handle, not the top part or the side part, so that the pull start handle is pointing at your right shoulder. Then bend your left elbow, which raises the front of the saw, and in 1 coordinated movement, push downward with the left hand (straightening the elbow) and pull the pull start rope hard, and fast. This method keeps the bar away from you, keeps the saw in your control clamped between your thighs, and because your left hand is pushing the saw downward, you are using the weight of the saw, to help pull the rope for you. Good luck!

    ​@@austinado16 Thanks for taking the time to provide such a lengthy and helpful reply. I followed your video and was pleased to see that with the covers off the saw was clean, hoses intact and wires electrically sound. After a cleaning of everything I was able to get it started and it ran for a few seconds (exciting!). But then I promptly died and became difficult to pull the cord again. I will have to watch some videos about carburetors and see where I can go next. Thanks again!!

    @@austinado16 fixed it!! I took apart the carb, gave it a clean and in doing so I found that there was indeed a crack in the fuel line. Luckily there was more than enough slack that I could remove that part, reconnect the line to the carb and away she went. I truly believe that everything on this particular chainsaw is stock - there is a badge indicating a manufacture date of 1998 and there was a similar date on the fuel hose (which I plan to replace). THANK YOU AGAIN!!

    @@inorganicinorganic6854 Great job!! When you order the fuel hose, order the OEM fuel filter for it. The filters will look white and clean/good on the outside, but get full of debris internally, and restrict the flow of fuel. So just cut to the chase, and hang a new filter, since you'll be in there anyway! Well done!

    I'm not sure what "stake ons" are, but if you're referring to the wire crimpers that I'm using, they are available from several manufacturers, and sources online. They are also on the Snap-On, Mac, and Matco tool trucks here in the US.

    Oh yeah and do you or anyone know if that black and blue wire are connect inside the shrink wrap section or are they just shink wrapped together. I made both ways , but no spark. Probably need a coil also. My spark plug is brand new and sparks on other things i tested it on. Or idk.

    The black wire and blue wire do not touch each other, anywhere, until the on/off lever is pressed down into the "off" position.

    Ya, when I was creating the video, playing back the individual clips, and doing the editing, it was obvious. Working on stuff with a camera sort of in the way, and making sure things are in view, is a little different then just standing there doing normal work.
