Great videos Beamer. If and when you decide to redo them or make new ones It would be nice to show a close up shot of what is being done instead of a far away shot. Just a suggestion

Hi Beamer, Thanks so much for the demo. It helped me a lot maintaining my Peugeut 103 LSD-U3. I was able to replaced my spark plugs with no problem at all. The Carb, I am still working on that. I am still afraid to touch it. I need to take a video of it while I am taking it apart so I will know how to put it all back :). I got some tips also on how to clean the chain and grease it back. That was easy. My next project after I figure out the carburetor, will be the brakes. Do you have any video on that? Bonie

How to Assemble a Moped Carburetor

Hi, this is Beamer and today we’re taking apart and cleaning a moped carburetor. We’ve already taken it apart and cleaned it, and now we’re going to start putting everything back together. With your body, you want to start with your float and needle that goes into it. The needle usually slides onto a little metal fitting right here. The needle has a grooved back so it can slide into there. And you take this and the hole where it’s supposed to be- you just want to slide it in so the needle goes right into that hole. Take the pin that we already pulled out of it. And now that the pin’s in there, make sure the float moves up and down freely without getting stuck anywhere. From there, we can reattach the jet down the hole it came in just put it right back in there. And then we can reattach the float bowl. Now you want to tighten it, but you don’t want to tighten it too much. It can strip the carb body, which would render it useless and you’d have to buy a completely new carb. So just give it about half a turn where you’re comfortable with it. There’s a rubber fitting so the gas can’t leak out of it, so as long as it’s tightly up against that, you’re fine. Now you take the main slide, and you’ll notice there’s the pin inside. There’s a small metal fitting that goes around the pin. And on the pin there’s multiple different grooves on there. That all affects the setting of the pin. Usually it’s second from the top. So if you ever take that off, just remember where it originally came from. Slide that back on, and there’s usually a protective metal piece that goes on top of that. And that’s how you put the carb body back together.
