- Hey guys thanks for watching today I tell you all about the n/t carb and how it works and various issues you may have with them. I hope this video helps you fix your leaking carb or just to understand how they work.
if you enjoyed please subscribe and comment down below I respond to about every comment.
Kid you are extremely advanced for your age! Your highly intelligent and your delivery is impeccable. I'm truly impressed, I subscribed!
really liked the way you speak young man! thanks for the free lesson in carbs never too young to teach and never too old to learn!!
I closed my petcock the other day and noticed air bubbles coming up my fuel line as it was draining into...somewhere? Bottom of my air filter is soaked, so obviously there. My float was at like 17 mm so I moved it to 21. Put some fuel in the line to check and no bubbles, level hasn't dropped. Can't wait to try it out in the morning - maybe I'm finally on my way to getting this thing running right. 😂
I really appreciate it, brother 🙏
No problem glad I could help out
Seems I have more to consider when searching for a better carb than what I have, very informative, thanks for sharing your knowledge
No problem bro many carbs on the market nowadays but the key is to not go to big for your engine set up. If your engine is fairly stock stick with the smaller N/T and Hp style carbs. But if you have do a lot of porting or have a real pipe on it a vm18 or pz20 may be the better option for you.
@@keeganhache6667 Don't forget when You talk about Jetting your Carb You need to mention that Jetting also depends A LOT on your Altitude!! The higher, the altitude, the fatter the jet you will need! Keep up the great work my friend!⚡︎👍🏁
The bending back of the floater pin thingy worked like a dream! Now I don't have to buy a new carb
Glad it helped!
Thanks for sharing your experience and knowledge. Well done.
hey buddy dont worry about what other people think about what you do on your channel its your channel do what makes you happy and have fun with it . i do know how people get up tight about things in the motorized bike community . and not just the subscribers some channels freak out to if you have a opinion lol not mentioning any names . you will figure it out if you keep up with the other channels . you might already know lol . just dont sweat it there are a million experts and non of there opinions matter when it comes to what you do on your channel .
Yes unfortunately this has happened more than once but all you have to do is ignore the negativity and keep making the videos like I did before. There was this one guy saying “you don’t know anything and your never right”. How ever when I clicked on his page all he had done to his bike was a banana pipe so it just goes to show how ignorant people can be.
@@keeganhache6667 its all good buddy just block him and keep doing what you do. he is just one person in a ocean of people . you will meet people like that alot there just not worth the time . ride safe little buddy
Thanks man I’m glad you understand I’m no professional but I try my best to explain things and that’s all that matters.
@@keeganhache6667 thats all that matters .
I noticed there's some strange rangers in the MB community. One guy kept calling me an idiot for saying engines can run on hydrogen, natural gas, mapp gas, propane,etc... Despite me showing him an overwhelming amount of evidence. He said it was all BS/a scam, that I was wrong/stupid & he was right. He's messed with 2 stroke engines quite a bit but apparently hasn't ever seen a common propane forklift.
Great video young man, amazing work all the way around very good mechanics and camera acting, editing etc.
Great video 👌👍 very helpful
Thanks so much! Glad I could help you out!
Good stuff!
Thanks check out some of my newer videos!
I'm building my first motor bike, from Amazon. mine came with an oring this time lol
Nice a lot of them don’t come with it but I just buy a cheap o ring kit for the carbs and that will fix most of the air leaks you will encounter.
This kid is the best thing to come out of Canada… besides Wayne Gretzky lol
Thank you!
No problem glad I could help you out!
Thank you for a well spoken & informed delivery. My question is: is it normal to get an NT with a float that has fluid inside of it? Incidentally upon my first start up it bogged down after about 3 to 8 minutes.
I had this same problem with mine last summer. Your float level is incorrect. Adjust it to 21mm. Also there will be a point where you have adjusted the float flap so much that the metal has become weak, and you will need to buy a new n/t carb. Or a rebuild kit
Love your videos brotha. Have you heard about the minarelli kits that came out recently?
Yes I want to get one eventually. Do now I will just mess with the China dolls lol.
Glad you liked the video!
@@keeganhache6667 I ordered the basic minarelli kit from eBay I already have motor kit for it so I’ll let you know how it is
@@justanothermotorizedbikech5138 awesome man just make sure you have really powerful brakes those motors out of the box still in break in can hit 50mph no problem
@@keeganhache6667 lowkey it is going on a huffy cranbrook😭😭😭. I still have to order brakes but I won’t hit the pipe fully until I get some for sure
@@keeganhache6667 idk man the minarellis are very fast. I was scared to go half throttle that’s how strong they are. It’s dirt bike fast
I needed a filter coz me rear tire was slinging sand & dirt directly into my carb intake... I had good results modding the stock restrictive NT carb filter by, #1 cutting off those 4 bottom plastic intake tubes on the cover, wrapping tape around the outside so airflow can no longer be sucked into them. Then cut a large oval hole in the back cover, cutout the inside plastic filter support screen (leaving the outer plastic ring & screw holes) Now it runs just as good as it does with the filter & housing completely removed.
But if I remove the tape so the bottom holes are also exposed. It doesn't run nearly as good, I suspect because the holes are causing the airflow to swirl inside the filter housing VS being sucked straight into the carb from 1 large oval hole cut back. In hindsight, I should have only cut 1 large round hole in the cover, directly inline with the carb intake hole (while also plugging up the bottom holes). To see if it'd run just as good with smaller round hole VS the large oval hole made in back.
I made the hole oval & as large as possible, going for the least restriction.
Wow sounds like you really dialed it in! I always recommend running a filter but as you stated getting the most flow out of one won't hurt either. This goes for a lot of things on these bikes you just really need to experiment with what works good.
Hi. I think I might have this issue, i might try what you are saying. I am noticing quite a bit of gasoline leaking into my air filter, i have the same nt speed carb you have.just needs figure out where to drain the gas out of the carb to
the kid i bought mine from is a grade a duster because as soon as i put gas in it, gas practically pours out of the filter, and when i took it off, i realized there’s only one screw and no gasket. could it also be the float height, or should i order a new filter?
Dont know what its called but at the end of the throttle cable, the brass pin with 4 or 5 different washer positions. I live at 5k elevation, What notch would be best?
Hi i have new bike kit and cant get it to run when i give it throttle i have bofeng carb ive moved the e washer all the way up on needle and its better but still wont let me give it throttle it will cruise at about 1/4 to 1/2 throttle and has issues with slight inclines
You pump that on the NT carb before you cold start. Pump it until you see gas coming out the filter. Then you'll be ready to start it. At least that's what I do and it seems to help with starting a cold engine.
No that will just flood out the engine remember to much fuel isn't good ether. All I do is pop the choke prime it 5 times and give it half throttle and it fires up first try.
My last kit came with an o-ring and a rubber washer. I figured it was for the intake and carb cap is that right?
Yes the rubber o ring goes inside of the carb and seals to the intake.
The other one your talking about goes over the throttle cable
I'm trying to find some type of gas/oil resistant non hardening/non messy putty to wrap around my carb/intake to insure no air leaks. So far the free window putty string I had laying around is working but I'm not sure how it holds up to gas & oil. I didn't wanna mess with smearing messy gasket sealer all over it, having to wait for it to dry & scraping it off & reapplying each time I removed the carb.
Would be nice to have some reusable putty. It'd also be good to carry some with you & come in handy for something like a leaking petcock valve or cracked fuel filter. You could stick some putty on it & make it home.
There is the stuff that I've tried out in the past and have had really good luck with there's a sealent called permamax The Right stuff. My dad's aluminum intake was leaking on his truck and it was because we just used ultra Gray which is good for light duty stuff so we use this permamax right stuff and it's easy to remove if you need to but it will still seal 100 percent.
@@keeganhache6667 Just seen they make several types of "the right stuff" ...I have maybe 5 different types of gasket sealer/maker laying just never bothered to try em on the intake yet.
I start typing away posting comments, not realizing how many & long they are, lol.....Since $5 gas is probably here to stay for good, I'm working towards a lightweight 40-45 mph, stealth motorcycle with pedals build that gets 80-100 mpgs.
In my case I always had to put in a bigger jet. Would run great up to 3/4 throttle but when I would give it full throttle it would just bog down cause it wasn't getting enough fuel. One of my engines I ended up with a 78 jet
Yup tuning can change drastically when something is up with the motor or carb. Check your float level you never should upjet that much on a chinadoll
@@keeganhache6667 not just a regular china doll I have every performance part they make on all my engines except nitrous but now that I know I can get more cartridges I'm getting that too
@@Westhelockpicker nos gonna blow it up lol let her get warm before hitting it
@@keeganhache6667 it's just a little shot and yea eventually it will but who cares these are throw away engines and besides it'll be fun
Hp carb was meant for a 21mm wide intake try a bigger intake it’ll pump up ya jam! And I’ll make a video soon bout the hp carb and send to ya show y how to not have issues with it
Ok thank you send me the link of the video when you post it 👍
hmm idk but what is that screw near chock? u dont have it but i have , does it makes fuel go faster in or what? i just dont know why my moped wont stay runing , i clean it few time but no result....
No it’s just a idle adjustment screw
Sometimes wen I hit the throttle it bogs at higher speeds. Like a muffled sound. Have no idea.
So I have the newer bofeng that came with my bikeberry kit.. but am I to understand that the jets they sell will not work ? 🤔
Yeah so you can’t just buy your average 5mm jets for most carbs. What you need to do is type in 212cc jets and then you will find the right ones. It’s because it’s a 9mm jet and it’s a great carburetor just harder to find jets. Go powersports has a lot of parts for 212cc engines so that’s your best place to shop
One way to find out exactly which part of your carb is leaking if you have a very slow leak. Is to stuff some pieces of toilet paper around the suspected areas then check it in a couple hours or day later.
I couldn't tell if my carb was leaking from the bottom drain screw,primer button, bowl gasket, fuel line into the carb,etc..coz the leak was so slow it wasn't visible. The next day after riding, there'd be a small puddle underneath the carb. After stuffing TP around suspected leak areas over night, I could see it was leaking around the primer button only.
Yes this is totally a good idea I had this problem recently on my pocket bike and I just stuffed some shop towels underneath the lower fairing came back the next day and it turns out my overflow is leaking so most likely my fuel Peck cock isn't keeping the gas from flooding the carburetor.
They painted the inside of my cylinder head. I pulled the plug & it had paint on it. It may be a common problem. I am correcting manufacturing defects! And I thought the climate was wrong for China to grow lemons.
do u get a VIN number and plates and register ur motorized bikes with the ministry of transportation in your province? in order to legally drive these on the roads in ontario, u need to do all that plus insurance and M(1, 2) license with at least L condition.
Yeah I live in Nova Scotia so the law here is that they can not go over 20mph. I have ridden my many cops and they don't care. My fastest build goes almost 50mph so it's honestly how you ride them.
@@keeganhache6667 be careful! Just because they haven't pulled u over, doesn't mean they never will. If u get pulled over and they prove the bike goes over 20, u could get a fined. In ontario the fine for riding without insurance is 50k.
@@xthe_moonx like I said I've driven past six cops and one of them even waved. Worst comes to worse I'll just hop on my dirt road and start riding the trails will never find me haha
@@keeganhache6667 I think if too many idiots get these & ride like idiots. That's when they'll start to crack down, like speeding- riding 35-40 mph in a 20 mph zone around traffic or too many car/motorized bike accidents where it's 100% the bikes fault. I got a mirror, don't ride like an a-hole & will be getting a better light & more reflectors.........On my motorcycle, I ride fast & have fun, I just do it in areas with no traffic ,instead of riding like an idiot in traffic like you see many YT motovloggers do. You see so many YT motovlog idiots crashing & drama road rage videos because they're a-holes to drivers in hopes of a drama/argument confrontation video for views. Iv'e been riding for years & don't get into road rage drama once a week like many YT riders.
So I should use crab that came with phantom? I have all 3
Yeah if it’s a brand new motor I would break it in with the stock carburetor then when the three tanks of gas are over then switch to a larger carb like the pz20 or Tm24. I know the break in period sucks especially if you have the upgraded parts already but trust me you have to let that motor break in right. Good luck to you
Thanks alot 👍🏾💯
How exactly do you adjust float height
Bend the float tabs up to 21mm
should we put lock tite on the threads of the case?
You can lock tight has heat resistance so a lot of people use them inside engines.
So putting it on the cylinder studs is a great idea so they won’t back out when you
Have to take the head bolts off. Seen that plenty of times
@@keeganhache6667 so my kit came with extra lock washers for the rear wheel sprocket? do I need a lock washer on both sides, or just on one? sorry to bother you again
@@audieallen9734 no all good to answer your question you need a lock washer and flat washer on the nut side so the back side. Not the front because you need clearance there for your frame
Fuel was leaking out of the air filter...then I just pumped the manual fuel pump, and it stopped leaking, when I turn the fuel line on... With no leaks at all...
Float level or piece of dirt in the carb needle
I watched this video because mine is 4 stroking and bogging down at top speed
I did a video dedicated to this topic! Be sure to check it out because I cover everything in it about carb jetting, needle adjustments, spark plug gap, ignition timing you name it.
Were to ge jets for th bofang
They are the same 9mm jets for a predator 212cc so just search those key words on Amazon or eBay
Bofang if only 15mm and the NT is 19mm. Bofang uses special jets you can't get so you can't tune it unless you drill it out. Nt carb is the best. Other 2 are junk.
Says the guy with a don butler engine
That "button " looks like a pop rivet
It is
Fuel leak fix failed me sadly
It could be the needle and seat itself. Overtime they will wear out and it will allow gas to overfill the bowl when the bike is perked. These carbs are cheap and easy to get so in your situation you are better off buying a brand new carburetor
The shaw carb has no way to a just the float
