  1. Ya'll need to take notes from this guy on how to make a tutorial.
    Keeps the convo to a minimum.
    Sticks to the points.
    Doesn't bet for likes and subs.
    Doesn't have an obnoxiously loud dubstep opening.
    Dude is easy to understand, speaks loudly, and clearly.

    10/10 would watch more videos from this guy.

  2. I had to figure all this out the hard way and here this guy just goes and explains it in 5 minutes. I still can't believe this is ALL there is to cleaning a lawnmower carburetor. That's IT?

  3. Thanks. I wish they made it all simpler. I dont' have most of these tools or understand most of what is said. I just bought a new one to replace my mower and on second time using it it hsa broken again. Have spent an hour already trying to get it working, oil change etc. There is no way I can do most of these things. They are too complex for me but thanks for the vidoeo.

  4. >>>   Expect the mower to run many many hours at a time, several days a week. At first we thought this was strange and it made us uncomfortable. Now that we aren't maintaining a lawn, we are fine with it.

  5. i took the bowl off of my mower and it had no holes in the bolts. It actually had two bolts. one attached to the carb and the other serves no function that i can see, other than perhaps draining the gas. At any rate I then removed the carb and sprayed cleaner in all of the orifices. the mower seems to be running well now.

  6. You're right. It looks like he loosened the carb. This is a sorta quick and easy way to clean the carb there are some better videos of taking the whole thing off. Esp if this one jet doesn't do the trick

  7. NO. You can see it in the video when he puts the bowl back on that he lifts the engine up in order to get the bowl on. The video however doesn't show how to loosen the engine so you can lift it up.
    I couldn't get the bowl off and therefore couldn't elign the gasket properly.

  8. I think it was the jet he took off first and cleaned, That loosened the bowl and that's what he bolted back on when he got the gasket and new bowl back on there.

  9. Good vid. Only thing is that I can't get the bowl off. In the vid you loosen the bowl and then there is a break. It's obvious when you're replacing the bowl that you've loosened something in order to get the bowl on and off. That part would be very helpful. thanks.

  10. My sleigh runs on reindeer gas. I can remember the Christmas of '39 when Rudolph first joined us. He was so stinky, that all of the other reindeer shouted out OWWEEE! We're going to laugh and call you names, and you're going down in history. They even demanded that he be last, right in front of me. That's when I made up the story about his glowing red nose, and guiding us. It wasn't his nose, it was the other (you know) side. Would a Jolly old Elf lie to you?

  11. Thanks very much for this. Very clear instructions, and made the procedure easy and it did not take long. Saved me a repair bill or having to buy a new mower! 🙂

  12. Really appreciate your video. After seeing your video I was inspired to clean out the old fuel in my mower which was needed to be used at another house but hadn't been run in 6 years. Thank you for your efforts!

  13. Thanks for your video. I made a mistake and left old gas in my mower over the winter. I can get it to run 5 to 10 sec if I put gas on the air filter; I was thinking my carb only needed cleaning. I cleaned out the old gas a week ago. I was going to take the carb off the lawn mower unit is found this video. I am going to try this, this weekend and hope that it works!

  14. Ok so aside from replacing the gasket. I thought id cleaner the nut really well. But I'm wondering now if or not I heard the click mentioned on the float bulb. If no click, then what? My Toro recycler still likes to either not start, or doesn't want to stay running once I start cutting. Unsure what I'm missing why it still won't run properly.

  15. Note, most B&S engines now have a very different Carb/tank design to this one…my MTD 5.0 early 90s had one like that, but my current Sprint 3.5/3.75/4.0 engines (I dont know what year they are, maybe late 90s/mid 00s, are plastic carb, 5 screws to tank, no float, nothing like that.
