    If only other diy vids were as well done as this. Every step, tool, and part included.
    As a DIY video this is excellent.
    Anyone giving this a thumbs down should not be allowed to use tools..

    Thanks Don! I have 2 Homelite saws that I've had for nearly 30 years. They run really well, though can be a bit tricky to start at times. Now that I see how to do the carb kit job, I may give it a try.
    I've learned a lot from your videos. Many thanks for your work.

    Great video! The Super 2 is one of the best all time saws. 43 years old & still runs like a champ. Still my go-to saw for pruning & general light clearing. Zero arm fatigue.

    I like the way you showed us how to take the saw apart, and re-assemble it. I don't have a Homelite saw, but the same procedure probably works on the Poulan, and Stihl saws also.

    Hey Dony, the hose going from the carb to the oil tank is a pressure line. These models did not have an oil pump. Uses pressure from carb to pump oil on the bar.

    Thank you Donnie, I have a little Homelite XL, Unfortunate for me I loaned it out,,, they couldn't get it running,, turns out they put the oil where the gas goes The gas where the oil goes, What's that old saying never let a good deed go unpunished. well I guess it's time to rebuilt the carburetor.

    Perfect timing again, Wow! I was just given one of these saws last fall, and even though it seems to run fine, it had sat for a very long time so I ordered the carb kit for it. Parts for these saws are starting to get hard to find, but they seem to be a great little saw. Thank you again :)

  • @Bird76Mojo76
    @Bird76Mojo76 4 роки тому +2

    You don't need to bend the throttle wire or risk breaking the trigger on this model. All you need to do is have all the screws out that hold the engine in the case. Once you start sliding the engine out of the case, the throttle linkage falls off of the trigger 99.9% of the time. Then, when you're putting the engine back in the case, insert it halfway or so, then reassemble the throttle linkage before inserting the engine all the way. Also, keep an eye on the coil wire, and the bar adjustment screw as it hits the inside of the case most of the time, keeping the engine from going all the way in.

    • @DiscoFang

      Disconnect that linkage from the trigger as you pull the motor out and you don't need your tongue. It almost releases itself.

    Thank you very much. I just got one of these fro. My wife's grandad. I was planning on doing a carb rebuild. One thing I haven't been able to find is was fuel mix to use. Any idea what ratio to use on this saw?

    • @PatrickWagz
      @PatrickWagz 7 років тому

      I came across one of these saws about a year ago. I have been using a 32:1 mix for about 4 hours of use, so far. Try to get an ethanol-free if you can find it. Minimum 91 octane.

    • @DiscoFang
      @DiscoFang 5 років тому +1

      I have had one of these for 20 years. I use a high quality 2-stroke oil that they say can be mixed half the recommended ratio. I use that at 40:1 in all my small 2 strokes and they run like champs with minimal smoke.

    Hi Dony....Great video library and most thorough I've seen. You've helped me tremendously trouble shooting issues and small engine repairs and up-keeping of my equipment. My hope is you'll read this question / issue I have and help with recommendation. I have a string trimmer, Stihl FS 80R. Idles ok but when ramping up rpm machine bogs down badly or cuts off altogether. My immediate issue is the black limiter buttons for the high and low adjustment. I need to remove them for full adjustment but can't seem to without feeling as though I'm going to break something and compound my problem..Can you help me with this. Thank you for your time.

  • @mainelyelectric
    @mainelyelectric 4 роки тому

    I have an old homelite little red XL I’m rebuilding the fuel system and tuning it up. I’ve read on many forums about the fuel ratio mix for these saws and I’m confused! It says to use 32:1 that is a lot of oil but that was back when you used just standard 30Wt oil. Now everyone says either 50:1 or 40:1 will be fine with the new high-quality 2 cycle oil’s. WHAT IS IT?? Thanks

  • @johncware66
    @johncware66 6 років тому

    Awesome video, thanks so much. I ordered a carb kit for my Super 2 a few days ago, good prep before putting it in. Right now my Super 2 (new for me, bought used) idles so fast that the chain spins even when the trigger isn't down. I'm assuming the adjustment of the 2 screws you showed will resolve that problem. Any advice appreciated of course.

    Hey man I love the channel and I inherited a homelite super 2 I just fixed the rewind and I want to access the carb but the screws holding everything inside the housing are stuck not sure if locktite was used and concerned of using heat to loosen them being I think it's in aluminum. It's almost a torx / slotted combination any suggestions before I really torque and strip them? I'm not sure how to send a photo of the screw it has 4 points internally and then steps up slight for the other 2 points becoming wider to a slotted drive.

  • @ryansilva8007

    Morning Don... I have a stihl 034 saw that is rough starting. When it does run you can change the rpm of the saw just by tipping it..Will idle ok on the ground but if you pick it up off the ground the rpms go up... Looks like an after market carb is on it. Impulse line ( yellow tygon) looks ok. Any direction? Thanks, and I hope you and the family are well.

    • @donyboy73
      @donyboy73  7 років тому

      the carb might need adjusting or a new kit. it's also possible that the saw has an air leak somewhere like a crank seal. also check impulse line first if it has one

      In the 1970's I lived in Alaska and heated with wood / coal. Had three Homelites of different sizes, and would cut 8 cord of wood per year. Those Homelites were great. Never let me down.
      I eventually moved back to Missouri, where I still cut wood, and so I again (about 8 years ago)bought a Homelite saw. What a disappointment. The quality is no longer there, and I gave up on Homelite.

  • @punchion
    @punchion 7 років тому

    I've had one of these saws for years. The only problem I have with it is the fact that it won't idle for any longer than a minute or two when I lay it aside while cutting wood. It will start up right away as soon as I pull the cord but when I put it down it shuts off after a minute or two.
    Other than that, a great saw!

  • @Pullingtractor
    @Pullingtractor 7 років тому

    I've never used starting fluid in any of my carburetor rebuilds or engine tune-ups. Because if the carburetor won't prime itself with gas from the tank, and if the engine won't start within a few cranks, using starting fluid will be a false indication that the carburetor is drawing adequate fuel from the tank. Because if the chainsaw runs out of gas while the customer is using it, what's the chances of most customers using starting fluid to get it started again? Very few.

    Where do you get parts at for this. The lawnmower shop by me doesn't have them I got 1 exactly like that. The only place I found a Homelite facility is in South Carolina and that's in the United States one place really

    Donyboy, I have this exact same saw. The spring on the recoil is very weak. Often times, the starter rope will rewind VERY slowly.
    Do you know if there is a replacement spring sold for this? Thank you, I learn so much from your videos.

      Patrick Wagz Have you tried cleaning and lubricating the recoil assembly? Had the same issue on a Super 2 and it was just that the recoil had built up a lot of dirt and debris around the recoil itself keepingit from spinning freely. After cleaning it works great.

      Okay, I'll give that a try. Thanks!

      Open up the coil mechanism, clean it and also untie the pull-handle and add a couple of turns to preload the spring. There's plenty of spring in there.

    Have you got a rebuild video on the Tecumseh carburetor with the extruded aluminum body, 632671C or universal # 520942?

      I don't think so, by the way what brand of house furnace is better?

      In my opinion, and this could start a knock-down drag-out wang dang doodle right here in your comments section, Goodman gives the best value, for a gas furnace, forced air. There's a lot to think about, though. Current fashion is run them a little under-sized. Are you replacing a furnace or building a new house?

      I want to replace my current furnace, I think it's an old olsen 80 000 btus natural gas

      You'll want to stay fairly close to existing capacity so there's no need to change duct size, and less of a chance of introducing noise to the ductwork. A quick Google search turns up a Goodman 80k BTU 96% efficiency for $800 or so. You won't use your existing exhaust stack or combustion air intake, but instead run PVC pipe for both. Also there will be a condensate drain tube and likely a condensate pump.
      Don't let anybody try and tell you $2400 installed - that's just excessive.
