    Unbelievable. Just absolutely mind boggling the way that you built that full-size model. I’ve been tinkering with these carburetors for about 30 years not really knowing what the hell I was looking at but now I completely understand them inside and out thanks to you. I’ve watched this video about four or five times. Absolutely amazing.

    Walbro should adopt this video as their main (and only) tutoring source to educate their engineers. I am a retired computer engineering prof from a local university, and I can vouch that this is an amazing piece of work done by Mr. Gould. I searched in the internet to get a good understanding how a Walbro carb worked because I wanted to learn about RC gas engines, but couldn't find anything substantial, just bits and pieces of info published by people who didn't know the entire mechanism. Finally, I started examining Walbro diagrams on Walbro website, trying to figure out the exact mechanism. I found out most of these diagrams were sketched for people who were already very familiar to Walbro carb, but didn't make too much sense to me (or novices that don't know too much about carbs). I am glad I stumbled across this video. Thank you again.

    I must watch this a few more times to let it sink in fully. All my life I have been almost blindly opening up carburetors and trying to get then functioning again. Sometimes with good results and sometimes with failure. I'm 62 now, pity I didn't know all this when I was 22. But however I have a walbro fueled chainsaw that dies out when accelerated and perhaps I can put this information to good use tomorrow. Thank you very much for this most informing tutorial !!

    I totally agree with "The Lawnmower Lady" and "David Mansfield". Your desire to educate others on something that is very hard to find information on is astounding, and your attention to detail and accuracy is almost beyond belief. I want to thank you for your efforts. I plan on using 2-cycle carburetors on 4 cycle engines, because the 2-cycle carbs can be set up as down-draft instead of the normal side-draft, allowing a longer intake manifold for added fuel mixture velocity. I was concerned with how to operate the pulse fuel pump, and to complicate matters, I confused the fuel metering diaphragm as the fuel pump. I plan to use a stainless steel tube inserted into the exhaust manifold so that the high velocity exhaust gas will create a vacuum in the SS tube which will go the the fuel pump pulse tube/entrance and pull the diaphragm against a spring to complete the push-pull action. After seeing this video, I now know that I can do it. Thanks again!

  • @patrickshaw8595
    @patrickshaw8595 2 ปีที่แล้ว +1

    These are "Demand Regulator" carburetors. They are not necessarily specific to 2-cycle engines. Tecumseh made tens of thousands of four cycle engines equipped with them.
    The 1958 Brown carburetor was the first of this type. The literature on them mentioned that they were a simplified Bendix RSA aircraft pressure carburetor. In 1960 Tillotson bought the rights to the design. In about 1968 Walbro began manufacturing these "diaphragm" (as opposed to "float type") carburetors - and they worked really well.
    One reason they worked so well was that they incorporated a "main fuel discharge check valve" to prevent air being sucked in the main discharge when idling. For years nobody minded air being sucked in the IDLE discharge when the main was pulling high suction. Later Walbro and others (many if not most carbs used on Stihl) incorporated idle discharge check valves as well. (To my knowledge no idle check valves were intended to disassembled and repaired)
    A big problem with these carbs is the diaphragms become stiff and "oil can" in and out taking a set first one way and then the other. Walbro now has kits to retrofit clear diaphragms guaranteed to never stiffen (but they must be used with a matching super thin spring steel flat spring - it comes in the kit)
    Hardly any mechanics know that you should know how to check the piston rings, cylinder base gasket, crankshaft seals and even the reeds/piston skirt valves for air leakage if your initial disassembly and renewal of gaskets and diaphragms does not yield good running.
    It's like this kids: 1) Compression (which includes crankcase compression!) 2) Ignition - which includes spark plug. 3) Then if you have an engine with a dry carb in place that also EAGERLY burns it's prime - You can get it wound up and un-pinch the fuel line and see if you can get the carb to take over from the hand (squirt bottle) priming that you are doing.
    YOU ARE WELCOME

    Thanks for the video

    Honestly, one of the greatest youtube videos I've ever seen. I've been working on small engines for years, learning everything I could, but I never truly understood the inner workings of a 2 stroke carb. This is amazing.

    Now I understand how the pull start works as well! I consider myself an expert after watching just once. I’ll soon be a genius as I watch it again. If this guy was a teacher in any of my classes I could have really been somebody. We need to find people like him to fill our classrooms nationwide.

    Wow. That’s the best explanation I’ve ever seen. What an awesome job you have done explaining the hole process. And an awesome job on the 3d enlarged models to explain the operation. You should get a gold medal for it. Extremely impressive. Thank You

    Excellent work. I thank you for the effort. Beautifully presented and explained and the 3-D printed carburetor deserves honorable mention. You deserve an award of some type for that work.

    Now this is how you teach people how things work, every detail covered and you speak at the perfect speed so we can understand what's going on. I have watched many videos on 2 stroke carbs and your video is the only one that explains every detail of how they work. Thank you so much for taking the time to do this for us. 😀👍

    The details of this video are beyond any other videos I have seen. Thank you for the excellent explanation and efforts behind making the model. I tried to understand the workings of this carburetor by myself but it did not work. Great Job !!!

    Durn! I've been rebuilding carbs for years and this is the best break down I have ever seen by far. It has given me a new understanding of things that can go wrong and how I might fix them. It also lets me see what I should expect to see when doing things like squirting carb cleaner in the various holes. Walbro carb are very common and the clones work just the same with minor variations. I owe you my thanks. Next time I lift a brew I'll toast you.

    Sir, this is hands down the best explanation I have ever seen. I can only imagine the time you put into making the model. I love working on my own equipment. After watching this video, I finally understand what's happening. I thank you.

    What an awesome video. I'm a 57 year old disabled vet trying to learn a new trade with 2 stroke engines such as weed eaters, chainsaws etc.. I've gotten my bronze through Stihl but have a ton to learn. I believe I could sit down with you and ask 100 questions. Thank you for sharing sir.

    IMPRESSIVE in every way!!! In design, manufacturing and ESPECIALLY your 3D scaling of the whole carb, ports, springs, just EVERYTHING!!! This is beyond anything I have ever seen for recreation and detailed explanation of the workings of a two stroke Wabro carburetor! I can't imagine the time involved making this. I definitely gave a thumbs up and SUBSCRIBED! WELL DONE SIR!!!

    Amazing giant model and perfect and beautiful explanation of how all the parts function, including all the drilled passages of the idle jet ports, especially the idle ones in the sidewall of the carb throat. The tiny idle drilled jets are usually the real troublemakers as they are subject to being easily clogged, causing stumbling and stalling when the engine is just coming off of idle. Bravo.

    Excellent tutorial! These carburetors are far from easy if you first encounter them, even with knowledge from other system's. This video makes it a walk in the park with none too little questions left. Very nice enlarged model, top tier stuff !

    Those enlarged 3-D printer models are brilliant. This is the first time I got any real understanding of how the tiny carburetors on 2-cycle garden equipment work. Lots of repair-tip videos out there, but nobody else takes the trouble to give the overview and explain the details of the fuel delivery cycle. For those who want to understand what's really going on inside these little marvels, watch this. Chinese factories may be able to turn them out today for $20 (I just bought two), but it took 150 years of creative thought and engineering to design and develop them. Appreciate that the next time you pull that starter cord.

    This surely is the very best explanation of how a 2 stroke carburetor works and should be viewed and studied by all of the small engine mechanics and buffs. BRILLIANT SIR!
