Hey motor heads. This video is mainly for the newer guys who are just starting out. If I missed anything please let us know in the comments. :)

Man I love this channel. I'd like to see him pedal over 40 mph. Some people don't talk out their mouths, sadly it shows their lack of common sense. Thanks for the new video hover. Excellent production and narration as usual.

I like how the NT carburetor looks like a skull. I painted the front of mine white. left the screw holes black and scratched out the paint on the grooves on the bottom.

DAMN video quality just keeps getting better and better!

My dad just built me a 80cc 2 stroke bike, love it to death, if I have problems I know who to ask

Always a great time learning from these vids thank you soo much buddy!! 🤣🤣 the "words are hard" part got me good haha keep it up

Good information for the new builders. Wish I had known about the choke nut when I had my first problem. That nut has a pinch point on the outside. That can open up when you pull from the inside nut.

Thanks for all of your helpful tips, LA!

Man she's pushing definitely love to see more videos this video reminds me when I use to do deep cleaning on my motors love the tips

The best working carb ever lol. Love your videos. Very helpful info.

Everything i need to know about the NT carbs thanks bro

Yesssss I've been waitng for a new video

I already watched this video but i like reviewing your videos! Because they are very interesting

The man himself is back😎

this is a well detailed vid. gonna go clean my carb now

The NT carb is based on a very old design and the priming button is actually a "tickler" as they called it back in the day and it's purpose is to flood the carb, over flowing into the engine to prime it (akin to pouring gas down the carb) and for it to work properly the intake manifold needs to be slightly tilted towards to engine or the gas just pours out the air filter. Useful on very cold days...

I took a China doll with a 100 CC and with a racing hat on it. And put APZ20 carburetor on it. It starts quicker, takes off faster. Gets to the top end quicker. And don't need any more gas than the other carburetors do.

The rod that pushes down on the float is called a tickler, it's a mechanical override for the float, used for clold start. In other words a primer, you push on it and at the moment fuel starts coming out of tickler you release it. If fuel is coming out of the tickler without depressing, than your float is set to high.

LA, when cleaning carburetor, use PJ1 super cleaner. (Amazon) Super cleaner does the same job, but less toxic and less smell. Evaporates very fast, and does not harm paint or plastic. Good luck with your channel.

16:29 I had this happen from time to time on my first couple builds. I remember is happening most often when A: you haven't used it in a little while. B: after running out of gas while riding. C: forgetting to turn your fuel valve on, and then needing the bowl to refill. Overall I'd chalk it up to surface tension between the bottom of the bowl and the bottom of the float, but after hearing a few of your guesses I'd say it's more likely just poorly machined parts, what you referenced as the "flap" catching somewhere and the float not having the buoyancy to push past the 'catching'.. thanks for the videos btw. They are very informative and very practical.

Good video i. Learned something new👍

I lost that float pin myself a while back, had to cut a finishing nail down with a hack saw to get it up and running, at the same time i lost the c shaped washer and had to cut a normal washer with a gap for the cable, for the good of it it worked fine

I would love to see an in depth video like this for the cns carb

Love that beginning part man I love that song cool

I'm sure it will be very helpful

Watching your videos make me want to ride

You can get away with boring out the venturi (?) or the horizontal passage, I actually had to in order to get enough air flow after switching to the new cylinder style with open transfers.

Love the intro

Running a wide open speed carb and recently installed mz65 clone pipe

Good vid!

You should do a video about the differences about an nt carb and a racing carb (just an idea)

Cool video i bought a new NT speed carb one time and the float sank as soon as the bowl filled up...it's still full of gas it won't come out and i can't find a hole or crack...it has to have sealed itself because it's full of gas and there's no wet spots where a crack or hole would be even left in the sun to raise the internal pressure

I’d recommend getting metal one sided sticky mesh for aquariums for the air filter and a cage

Speed carb has been good to me, never let me down. Hard to find an exact spare.

Mnn carburetors, the strangest mystery known to mankind :D

I want you to test the gt80 reed system Give some tips about tuning it

hay would eneythang happen if i left the rear back sprocket ragjoint instaled backwords ?

My carb is good with the float the jet is not clogged but it only runs with the choke slightly on what do I do because I've tryed everything but nothing helps sadly

Is there a major difference between the yd 100 and a 66/80cc engine from the same company?

It may be user end issue but I went back to using 4 stoke engines instead of two strokes because every once in a wile the flote would get stuck and start leaking fuel everywhere, actually not leaking gushing fuel everywhere.

What do u think the problem would be if my 80cc motorized won't hit full speed

On those specific carbs i cant comment. However the rubber gaskets almost always last longer in general, at least from my experience

It sucks that I discovered this channel after i put my bike together but my bike is holding up fine

Dang I wish my bike ran that good!!

We have talked before did you try the expansion chamber formula in my opinion the nt carb is the most simple and easily tunable carb there is I have found only one shortcoming. The donut float where I live in colo I challenge some very steep grades my tuning test. Is a place called skyline drive a steep rocky hog back with a paved road over the top the only problem is the first part is about a quarter mile 11 percent grade and steeper with no starting run it took me months to eliminate the issue due to the location of the fuel inlet and the donut float when you hit this steep grade the float sticks and it floods and as you know without gears there is no coming back and I would have, to turn around the solution making a manifold with a 90 degree bend to the, side and no more problems ,! Once agian I'll mention tuning the length of your lead in pipe before the expansion chamber 8 to 11 times in length as the diameter of your exhaust port at 32 to 1 oil mix and tuning your exhaust you shouldn't have any blow back thru the carb certainly not to the extent of oiling your air breather huge gains in low and mid power!

Have a problem put a new jug and piston on my yd100 and it's not running properly it only runs on choke and spits gas out the back of the carb,why is that? Thanks in advance

Hey man I just got an 80cc today was riding it and ran damn good however I started messing around with the airbox and removed the filter then it ran fine for a little bit then it wouldnt idle down at all and was running away with me on it only got it to stop with both brake levers and clutch in with pressing on the kill switch then I went to add the filter again and adjusted the throttle cable a bit for it to never run again idk what I did to it getting a new spark plug and hopefully it turns over again also disconnect kill switch because I thought it might be accidentally tripping.

The beginning of the video killed me

first time builder i have a zeda 80 fire storm . on the side of my carburator it say bo fong is this a new style carburetor. what style jets do you think will work .

If you do a light oil soaking the cork gaskets always last longer assuming it's real cork, rubber is prone to the fuel eating away at it and dry rot, cork will never dry rot if oil soaked properly

I have to use the primer to get my bike to start, if I don't it takes me a block to get my bike to start when it's cold

Have you ever had a fuel filter dissolve? Mine broke up into tiny sugar like pieces and wrecked my carburetor. :( Is this common?

I have an hp carburetor because my nt does not seal, the hp will idle high and the idle screw does move the slide up and down but when I try to move the idle screw to the lower idle area the engine does not do almost anything. It is not an air leak because most of the time when I rev the rpm goes down very quickly. What could be causing the problem? There is a fuel filter in the carburetor and one in the main fuel line. could the one in the carb be restricting fuel in the carb and giving it more air causing a higher idle? How can fix this problem and get my bike running well.

Hello. How do you not have your back wheel wiggle going at a fast speed?

Only thing stopping me from trying to clean the carb is it leaks from that point on after putting it back together

I have been using these for years in nyc. Just pedal when u see cops and dont go nuts

I have a china doll motor with an expansion chamber and racing carb I changed the Jets on the racing carb but engine still get super hot any suggestions for cooling? I also run 25 to 1 fuel ratio

I Drilled out the needle seat, so it was bigger, and it ran faster. Ran idle better it needs to go to a 65 or 70.

My friend bought a 50cc motor kit a chinese one from amazon and was outrunning me when it was stock half throttle no peddling and i was on a normal bike just not even close to keeping up

I have 4 nt carbs I use for parts....

What should you do if you have a new bike but it only runs with the choke on

I mean I guess I’m still newer? I got mine a few months ago. But I have a question, whenever I start my bike it sometimes just shuts off. Should I turn my idle up or down? It also tends to do this when I rev and it’s still warming up. Also I love your content!

I think he had that nt carb hooked up to his ford

is it worth upgrading carbies or are these just fine?

10:25 are your thumbs double jointed?..

If you wrap electrical tape around where the cable comes in for the throttle you won't get as much water in your carburetor that's what I did

A big thing people tend to forget is every time you are done riding, drain the float bowl. Very underrepresented piece of carb maintainence. If you let it sit. The ethanol with fuck up the carb. I drain my float bowls after every ride and turn of the fuel tap. Easy insurance so I can keep my carbs for a while and save as much money and time as possible. DRAIN YOUR FLOAT BOWLS PEOPLE

I don't think that guy who commented can pedal at 30mph😂

BY FAr the sicKest moTorbike viD iN hiStoRy!!!!!!!!!!!!!!!!!!!!!

I gave my motorized bike and 3 motors I had away ama keep building more bikes just have to save money for that

If you have a big enough frame use a p z twenty improved

I have two motorized bikes a beach cruiser and a mountain bike which I put a back seat and pegs on. I'm pretty sure they're street legal but I'm only 12.

Dope I got one but it's broken 🤣🤣🤣🤣

I wish I could pedal 40 mph 😂

A can of air works good for these kinda jobs

same power of a moped for a fraction of the price im clearly gonna get a moped 💀

As silly as this sounds....2 years later put the crease down. If it's defective some gas might get in but due to physics it won't be able to fill completely. With the crease at the top all of the air can escape

I literally pass every cyclist I see with like 3 times the speed

#1 TIP: Do not take off the carb bowl in the grass! Bahahaaa

If he thinks he can pedal that fast, I want to race him for some serious $

lol my 66cc can do 50mph

i can pedal faster than that, on a 5000 watt ebike with pedal assist lol that cost about as much as all of hovers bikes combined at least lol

Nt carb fucking sucks what's a better one I can slide right over my intake manifold like the nt carb?

It's a needle and seat . But them carbs run ok out of the box but has no air intake things like 1/4 inch so to get it running and break it in is OK but anything after that junk .

I like how the NT carburetor looks like a skull. I painted the front of mine white. left the screw holes black and scratched out the paint on the grooves on the bottom.
