Thanks guys for this super Video. Really helped me to make the translation of "Carburetor-the theory" to what the moving parts look like in reality. Pretty neat little thing these Carburetor's!
Thanks for the explanation. You may not be using the right terminology but you know what your talking about. Moreover you have great teaching skills. Keep up the good work.
this is known as a CV Carborator.some even have a sloped plunger and an extra return spring. The most common problem for not starting is a stuck needle valve in the float bowl. you may have to retune the needle valve a good rule of thumb is to start the engine to rich and make it leaner for a 2 cycle engine you never want to fuel starve an engine that relies on the fuel for lubrication.
there is no difference on 2 stroke carbs except the volume of air that can flow through it and the engine will only pull so much air so a "high performance carb" wont improve power unless your engine is high performance.
Not a drum but a reservoir or bowl. You should have explained the Venturi principle where the moving air from intake. That pressure is positive to the surface of the fuel in the reservoir. Hence allowing fuel to rise up the jet, which of course is regulated by the pin. Lowest notched pin allows more fuel to rise, higher notched pin, lower amount of fuel. The fuel that makes it up is mixed turbulently by that same vaccum air from intake. The higher the throttle, the higher the vacuum, hence both air volume and fuel volume increase. Their flow rates increase and must be dissipated by the explosion inside piston. 2 cycle, oil/gas 1 stroke grab the fuel/oil/air into piston, another stroke to compress, explode, and discharge exhaust. Great video though
the slide (the part in green) contorls air flow. the fuel comes in through the brass nipple into the float bowl. the float regulates the amount of fuel in the bowl and as the bowl fills up the float floats up pushing a neeple attached to the float up into the hole in which the fuel comes from to keep from over filling the bowl. fuel is then pulled out of the bowl by ventury (i think thats how its spelled) through a tiny hole called a jet. the jet controls how much fuel the engine gets and you can change the jet to change the air/fuel ratio. the more the slide is opened the more air is pulled through the carb. the air pulled through the more fuel sucked through the jet.
ahh ok, thats what I was looking for. My idle is good but my high end leans out. So I need to open the jet slightly to allow more fuel to pass. The kid is lacking a dynamic description, he only explains the static condition.
I think you should make a carburetor maintenance Video, if you could: thing's to look out for and thing's important to check and maintaining maybe schedule suggestion. One more thing, I don't know how many people have got sugar added to the tank( you know what follow's) but I did, and I wonder if the carburetor got toasted or it can be cleaned and saved?
if the carburetor does not fit under the bike frame directly to the motor like its supposed to, would making an elbow for the outlet to attach to mess anything up?
I'm missing the air intake didn't come with my bike, you can see the choke and see it cover the hole when you move the lever. When I turn the fuel line to on it pours out of the carburetor from the choke hole. Is that normal since I'm missing the air intake?
My bikes cylinder fires so I clip the throttle but it feels like it’s not doing anything eventually I’ll run out of breath pedalling it so I’ll pull the clutch when I’m coming to a stop still blipping the throttle and it cuts out almost instantly is it the throttle cable the issue ?
Can the carb sit at an angle upon fitting or does it need to sit up and down perfectly. Plus is it normal for feul to come out of tickler button and idle screw.
Can anyone help me my bike would start but would shut off when I take the choke off, so I took the carb apart and dumped the fuel in the bowl. It then started fine and idled fine, then I drove my bike for a little bit and then suddenly the rpm's went quite high when not touching the throttle? I didn't have much fuel in my tank, I think it was empty but will it do it again when I put fuel back in the tank
Fairly easy explanation. I've recently acquired one of these little motors and the first thing I did was to tear apart the carb and clean it out. Just a couple of points. The bottom of the carburetor is commonly referred to as the bowl, not the drum. I did have one question; what is the purpose of the spring-loaded pin on the side of the carburetor opposite the fuel inlet? It doesn't seem to have any adjustment, and its in the wrong place to be a bowl drain...Ideas?
+Eric Vega It's the bowl shut off. When fuel fills the bowl, the float raises and that little valve and shut off the fuel into the bowl (somewhat). I say :"some what" because, if you do not have your tank petcock closed then fuel can and will continue to seep into the bowl, getting by that little float valve. And yes, the guy making the video is more concerned with making the video than actually knowing WTF he's talking about.
+Buzzards Bass no, I'm not talking about the needle valve which is controlled by the float. There is a spring screw on the outside of the carb that I can't figure out. Maybe a mixture screw?
That's the IDLE screw. Stock adjustment AKA the place to START when you don't know where you are; or, as you did, you cleaned it so everything is now virginal again. Turn that spring loaded IDLE screw all the way in and then back it out four full turns. That's the starting point. Fire it up. Warm it up. You'll have a good idea where to go for idle adjustment. To LOWER the idle you turn that screw counter clockwise (OUT).
Question using 7:19 as a still shot. When my throttle is fully released, the plunger is quite less than halfway open. How do I remedy this? Or do I just always pull the throttle ever so slightly to even it out? :/
good explanation. most people don't know what a carburetor is now a days. I was gonna get the high performance carb but after all the videos I watched it doesn't seem worth it
Looking at the picture at 16:06, there is what looks like an adjustment screw on the right hand side, and then another port behind it with a gold plastic cap over it and what looks like stranded wire sticking out the bottom of it into the float bowl.....What are these two items and what do they do? Thx
that's a primer button and the tube that goes down into the fuel. it doesn't really work, but it's supposed to pressurize the bowl and force a little fuel up into the venturi to aid in startup
sir good day, i have a problem with my carburator, every time i park my motorcycle after a minute ride the fuel get out in over flow hose? how can i fix it? thanks
Thank you so much. Is there any address I can send my thanks to you through the mail for making this video? You deserve something for this it is very nice you made it. ❤ nicole
Hi on my 80cc engine, it won't start, I have good spark, i place my finger over sparkplug hole, i feel pressure and vacuum, i replace sparkplug, i take carburetor off manifold, i place finger over the hole turn over motor, no sucktion, so it's not sucking in fuel, I'm asking, what can be the problem? Rings? Maybe piston in backwards? I've been fighting this for 2 weeks now, any suggestions please, I'm feeling pretty lame and frustrated. Thanks
I have this ! But the jet that's ment to pull fuel through doesn't . So no fuel gets into the engine :( . All the jets are new and also a brand new carb . Still no luck !
So my bike only runs with the air filter button facing up. When im driving and push it down to take speed it shuts off. I been driving it wile is up,but is slow. Can you explain why when i push it down it wont work?
If you are talking about the choke valve, it is intended to be ran in the up/off position. The purpose of a choke valve is to provide a leaner supply of fuel during start; typically needed in cold conditions. Putting the choke valve to the down/on position will restrict the supply of air, that is a critical mistake at higher speeds. If the engine is not performing as intended, the carburetor idle screw may need adjusting. Start at a default neutral position, about 3 full turns off from being all the way in. Adjust it a half turn at a time, in or out, to find the ideal idol rpm. Another problem may be a loose compression head. Check that all bolts are properly tightened and that the head is securely seated.
Yes,it turns on n rides when cold facing up,but when i pull it down to take speed once is warm,it shuts off. It only rides wile is up. 10 miles. Slow. Put i push it little by little down it starts taking speed than it shuts off so i pull it up n it turns back on.
Our apologizes, we seem to have miss worded our instructions. We meant to say that it is a critical mistake at higher speeds to have it in the down/on position. Having it down will restrict the flow of air, which is needed for combustion. Having the choke on is only needed when trying to start the engine, specifically if it is cold; it should never be turned on when riding, as it will impede performance. The problem seems to be an issue with the fuel and air mixture. We have a video on adjusting the carburetor which should solve your problem. th-cam.com/video/XAaKSII_vbo/w-d-xo.html
I had the same issue, Engine started, no acceleration. I fixed this by changing the C clip on the needle appropriately to my fuel mixture, which was the breakin period, and I put it back in the carb. Make sure the needle is setup properly by watching a video. This is what fixed the no acceleration issue for me
I just tore it apart this morning cleaned it and put back together it seems to be working right now it's not perfectly level but I've seen way worse than my situation so I don't know it's too cold to be out running it for a long time right now ....thanks
Daniel Terry choke just controls how much air goes in the engine. When you turn your engine on, you keep the choke closed and then as the engine idles you want to slowly open the choke valve to let more air in
Thank you ... Nice explanation ... ! Also I think the lever like thing made of brass will be the choke ... Right ..? Most of the time I am confused that , The choke is intended for cold start purpose ( Allowing more fuel flow to the carburetor ) ... then why we are putting the motorcycle in choked mode when we have not enough fuel in the tank .. ?
Dale, those are a typical 10.00 carb for motorized bikes from China. You can get them all day long for around 12 dollars on E-bay. Ive replaced my stock Mikunis on Suzuki JR 50's with these and made them twice as fast after mods so dont count them out. For the price and simplicity they are pretty cool carbs.
That brass tapered rod is NOT the jet. But, it DOES go into the jet, to control the mixture. Now, WHERE is the idle mixture screw? 2 strokes need to run much richer at idle, to have a slow powerful idle. I've got 2 (or is it 3) of these CHEAP carbs, and cannot get a decent idle on any of them. I've also got the expensive carb, but that brass inlet tube FELL OUT! It also doesn't have an idle mixture screw! Yes, all 4 (or was it 3) came from BikeBerry, and is the reason I no longer shop with BikeBerry! Matt, can you get your money back, from the school that sold you the degree? You got HOSED! I didn't graduate from High School, but I KNOW the difference between a jet and a metering rod! steve
Not a bad description visually but Matt should be ashamed of himself for a mechanical engineer. The description he gave was full of downright wrong terminology and wrong facts. Eg 8:29 the bowl (not drum)'s purpose is NOT to regulate the air fuel mixture. That's the job of the jet pin, as he correctly mentioned the little clip has four notches and adjusting the position of the clip will adjust the reatio of the mixture. The bow'ls purpose is to provide a regulated reservoir for the jet to suck fuel from. Also I would have liked to hear some more practical advice eg why you have the mixture adjustment, why where when and how it should be set, how to adjust idle screw ect.
Does this piece have to sit perpendicular or can it be angled at a 45 degree angle? I am installing the motor in a tandem bike and I can't fit this piece straight because the space where the motor goes is not as big and is angled differently. I can send a picture thanks
an old comment, but you might need an offset intake manifoldso it sits off to the side. straight up and down is best but 15-20 degree is probably the most you can tilt the engine
OK, for the rest of you, Matt has LOST IT! At 9 minutes or so, let me correct. That lower chamber, is the "float chamber." Called so, because it has the "float" in it. (Not the floater.) The device works surprisingly like a similar device in your bathroom. Your toilet! Both have a chamber, a float (not a floater ask Eddie Murphy and Hugh Hefner about a floater) and a shut-off valve. Oh, the "floater" doesn't push down. (10:45 or so) that would be a "sinker." the float, since it floats, (that is why they call it a "float") floats, and slows or shuts off the fuel flow. Matt, 15:55, SERIOUSLY! Talk to some Mechanics! They (we) work on this stuff. You've NEVER gotten your manicured fingers dirty! Your ignorance, (and ALL of BikeBerry's is showing! BikeBerry, PLEASE keep posting this garbage, because I can "hit it out of the park" while drunk! steve
Steve Skouson what about if yall mechanics stop yelling at comments and start a fcking good stuff channel where you guys can gain money and good people-viewers could really learn to set up things good...
We're sorry you had a bad experience with our products and services. We do try to help however we can, but there are company policy's and legal restrictions that prevent us from fulfilling the exact wishes of our customers. We do try to work around these restrictions for a happy medium whenever we can, but that is only possible with the help and cooperation of our customers. Often times we try to provide an alternative that will minimize additional time and costs.
the part in blue is the air filter the part in green is the slide the part in purple is the float bowl. if your going to make a video to educate people make sure your educated first
Jesus wept, lol. I appreciate your attempt to explain carbs, but your "I'm gonna ad lib it" approach is, honestly, awful. Write a script! Use it! You need to use STANDARD NOMENCLATURE for the components. That will allow the entirely ignorant noob to relate your effort to written references, parts lists, and manuals. Figure out the similes you can use that relate to common as dirt items that even the dopiest among us can relate to. Don't forget the actual "target ratios" that are needed for a gas motor of any type to actually run, lol. If I had no clue going in, this vid would only confuse me more, and possibly convince me it was a subject far beyond my ability to comprehend. That equals your company losing my biz, which I'm fairly confident isn't the goal you had in mind. The better you inform your target audience, the better the chance they will become satisfied repeat customers. That goal is entirely missed, I'm sorry to say.

Thanks for making this video, I disassembled the carburetor and wasn't sure if I assembled it back corrrectly
Thanks guys for this super Video. Really helped me to make the translation of "Carburetor-the theory" to what the moving parts look like in reality. Pretty neat little thing these Carburetor's!
i appreciate you thanking your time to make this explanation,
Thank you.
Dude! Appreciate you! I've seen the see through carb and your explanation was spot on and even better. Props to your still photo walkthroughs
Great video. Thank you so much for taking the time to do this. God bless you!!👍👍👍
Thank's for taking the time to make this video.
Good stuff.
Great work - thank you for the video.
amazing work - You learned me how to care about this thing.. now im ready to buy this engine :) Thank You very much, greetings from Poland
Excellent video.Clear explanation.Thanks.
good stuff and nicely explained
Great video!
very lucid explanation. plese upload more videos on automibile stuffs. thanks a lot.
Very professionaly explained.
Thanks for the explanation. You may not be using the right terminology but you know what your talking about. Moreover you have great teaching skills. Keep up the good work.
wow man super good explanation!
Cool video thank you! 😊
thx man you helped me alot :)

you should do a video on what's the difference between a standard carburetor and a high performance carburetor.
there is no difference on 2 stroke carbs except the volume of air that can flow through it and the engine will only pull so much air so a "high performance carb" wont improve power unless your engine is high performance.

Matthew Weisenburger so what is a HP engine?? "80cc"???

Venturi. Good explanations, why do asshats like this dude, that only half, kinda, knows what they are saying, make these videos. Stupidity.
ahh ok, thats what I was looking for.
My idle is good but my high end leans out.
So I need to open the jet slightly to allow more fuel to pass.
The kid is lacking a dynamic description, he only explains the static condition.
what should be the position of choke lever? Does it need to be changed before and after starting engine?
The little gold looking lever near the air intake is what for again? And what switching it from the left to the right does what? I'm sorry new to this
the little clip to adjust the fuel to air mix snapped where can i get another one????
I think you should make a carburetor maintenance Video, if you could: thing's to look out for and thing's important to check and maintaining maybe schedule suggestion.
One more thing, I don't know how many people have got sugar added to the tank( you know what follow's) but I did, and I wonder if the carburetor got toasted or it can be cleaned and saved?
Thank you.
Do you have a breakdown on the HP carborator?
There's a piece on that he's got right there on mine not only lose but not sure how I can adjust it and keep it from dieing
Thank you
if the carburetor does not fit under the bike frame directly to the motor like its supposed to, would making an elbow for the outlet to attach to mess anything up?
Curious... What would be the potential outcome of attempting to engage throttle without a jet needle installed
I'm missing the air intake didn't come with my bike, you can see the choke and see it cover the hole when you move the lever. When I turn the fuel line to on it pours out of the carburetor from the choke hole. Is that normal since I'm missing the air intake?
My bikes cylinder fires so I clip the throttle but it feels like it’s not doing anything eventually I’ll run out of breath pedalling it so I’ll pull the clutch when I’m coming to a stop still blipping the throttle and it cuts out almost instantly is it the throttle cable the issue ?
how long is the length of the carb needle? trying to make my own as i lost mine
how to properly install the throttle and cable cuz I have to much play in it and can't seem to fix it
what happens if i dont have a filte
r on, will my bike still start?
I have recently had a problem wirh the dive sprocket.(the 10 tooth one).and i cant find any videos to figure out how ro remove it.can you please help
Do you need the kill switch thats on the air intake
Can the carb sit at an angle upon fitting or does it need to sit up and down perfectly. Plus is it normal for feul to come out of tickler button and idle screw.
it can sit at a slight angle and fuel should not leak from anywhere on your carb
You should explain what the float tickler does. Most people think its a primer pump.
witch way does the float go in ?
Can anyone help me my bike would start but would shut off when I take the choke off, so I took the carb apart and dumped the fuel in the bowl. It then started fine and idled fine, then I drove my bike for a little bit and then suddenly the rpm's went quite high when not touching the throttle? I didn't have much fuel in my tank, I think it was empty but will it do it again when I put fuel back in the tank

good explanation. most people don't know what a carburetor is now a days. I was gonna get the high performance carb but after all the videos I watched it doesn't seem worth it
Looking at the picture at 16:06, there is what looks like an adjustment screw on the right hand side, and then another port behind it with a gold plastic cap over it and what looks like stranded wire sticking out the bottom of it into the float bowl.....What are these two items and what do they do? Thx
that's a primer button and the tube that goes down into the fuel. it doesn't really work, but it's supposed to pressurize the bowl and force a little fuel up into the venturi to aid in startup
My best guess would be the screw adjusts the low air fuel mixture and maybe the gold cap is a vent but that is my question too.
sir good day, i have a problem with my carburator, every time i park my motorcycle after a minute ride the fuel get out in over flow hose? how can i fix it? thanks
the float needle is not seating properly, it should block incoming fuel when the float is at the top.
Other reason is the float might be leaking.
I have one of these and I'm having an issue with it being on for a few minutes and as soon as it heats up it cuts off like bogs out what could that be
Probably not using high octane gas. 93 octane is suggested. Detonation sounds like. My guess. am no pro though.
what was this filmed on?
where can i find one of those air intake filters?

That's crazy, this whole time I thought the narrator of the Bike Berry vids was Tony Hawk.
Hi on my 80cc engine, it won't start, I have good spark, i place my finger over sparkplug hole, i feel pressure and vacuum, i replace sparkplug, i take carburetor off manifold, i place finger over the hole turn over motor, no sucktion, so it's not sucking in fuel, I'm asking, what can be the problem? Rings? Maybe piston in backwards? I've been fighting this for 2 weeks now, any suggestions please, I'm feeling pretty lame and frustrated.
Thanks
Did you get it
thnx
can anyone tell me how I should adjust the idle adjust screw? I just kinda have it half way turned in and I'm not sure how i should use it.
MrJabber22 Turning the idle screw in more will increase your idle RPM, turning it out will lower your idle RPM!
BikeBerrycom how can I make it run faster ?
+Georgemain coq turning tot the right
MrJabber22
when i pull the cluch handel in the motor runs real hi how do i fix it
Susan Fogg you have to adjust the throttle screw at the top of the carburetor and reduce the tension on the spring
but the fuel should go into the engine in state of vapour, how it will be vapour ??
its a carb not fuel injection it doesnt vaporize all of the fuel
?How fat can I go on the main if I put a bunch of tuning mods on the bike????? I am at .80 main jet and plug says go richer. Anyone?
I have this ! But the jet that's ment to pull fuel through doesn't . So no fuel gets into the engine :( . All the jets are new and also a brand new carb . Still no luck !
So my bike only runs with the air filter button facing up. When im driving and push it down to take speed it shuts off. I been driving it wile is up,but is slow. Can you explain why when i push it down it wont work?
If you are talking about the choke valve, it is intended to be ran in the up/off position. The purpose of a choke valve is to provide a leaner supply of fuel during start; typically needed in cold conditions. Putting the choke valve to the down/on position will restrict the supply of air, that is a critical mistake at higher speeds. If the engine is not performing as intended, the carburetor idle screw may need adjusting. Start at a default neutral position, about 3 full turns off from being all the way in. Adjust it a half turn at a time, in or out, to find the ideal idol rpm. Another problem may be a loose compression head. Check that all bolts are properly tightened and that the head is securely seated.
Yes,it turns on n rides when cold facing up,but when i pull it down to take speed once is warm,it shuts off. It only rides wile is up. 10 miles. Slow. Put i push it little by little down it starts taking speed than it shuts off so i pull it up n it turns back on.
Our apologizes, we seem to have miss worded our instructions. We meant to say that it is a critical mistake at higher speeds to have it in the down/on position. Having it down will restrict the flow of air, which is needed for combustion. Having the choke on is only needed when trying to start the engine, specifically if it is cold; it should never be turned on when riding, as it will impede performance. The problem seems to be an issue with the fuel and air mixture. We have a video on adjusting the carburetor which should solve your problem.
th-cam.com/video/XAaKSII_vbo/w-d-xo.html
Thanks so much for ur help. After adjusting it a few times,i seem to get a better hang of it each time. Works great.
When I pull the throttle, I don’t go anywhere ... I don’t accelerate . How do I fix this ?
I had the same issue, Engine started, no acceleration. I fixed this by changing the C clip on the needle appropriately to my fuel mixture, which was the breakin period, and I put it back in the carb. Make sure the needle is setup properly by watching a video. This is what fixed the no acceleration issue for me
Can u plz tell me why there is gas pouring out of my air filter. ..this is my fifth bike. ..never had this problem before
Maybe bad carburetor , new one should solve it.
I just tore it apart this morning cleaned it and put back together it seems to be working right now it's not perfectly level but I've seen way worse than my situation so I don't know it's too cold to be out running it for a long time right now ....thanks
Can someone explain how the choke works on the HP carborator?
Daniel Terry choke just controls how much air goes in the engine. When you turn your engine on, you keep the choke closed and then as the engine idles you want to slowly open the choke valve to let more air in
@@nikolasstankovic6794 I was talking more so about the mechanics...
There's a mechanism that releases it at full throttle.
Daniel Terry woah really? Thats kinda cool
Thank you ... Nice explanation ... ! Also I think the lever like thing made of brass will be the choke ... Right ..? Most of the time I am confused that , The choke is intended for cold start purpose ( Allowing more fuel flow to the carburetor ) ... then why we are putting the motorcycle in choked mode when we have not enough fuel in the tank .. ?
with choke, in effect you get a richer mixture bcs the choke is limiting airflow
what kind of carb is that?
Dale, those are a typical 10.00 carb for motorized bikes from China. You can get them all day long for around 12 dollars on E-bay. Ive replaced my stock Mikunis on Suzuki JR 50's with these and made them twice as fast after mods so dont count them out. For the price and simplicity they are pretty cool carbs.
nobody explains the choke
Sounds like someone is hitting the bong for the first 2 mins
Oil, or fuel

That brass tapered rod is NOT the jet.
But, it DOES go into the jet, to control the

Now, WHERE is the idle mixture screw?
2 strokes need to run much richer at idle,
to have a slow powerful idle. I've got 2
(or is it 3) of these CHEAP carbs, and cannot
get a decent idle on any of them.
I've also got the expensive carb, but
that brass inlet tube FELL OUT!
It also doesn't have an idle mixture screw!
Yes, all 4 (or was it 3) came from BikeBerry,
and is the reason I no longer shop with BikeBerry!
Matt, can you get your money back, from
the school that sold you the degree? You
got HOSED! I didn't graduate from High
School, but I KNOW the difference between
a jet and a metering rod!

It just sets idle speed. Nothing else. In for faster, out for slower.
Why does my engine race?
Donald Yeager ?
Does this piece have to sit perpendicular or can it be angled at a 45 degree angle? I am installing the motor in a tandem bike and I can't fit this piece straight because the space where the motor goes is not as big and is angled differently. I can send a picture thanks
a 45 degree angle is too extreem it can be at a slight angle but too much and the float will not work properly
an old comment, but you might need an offset intake manifoldso it sits off to the side. straight up and down is best but 15-20 degree is probably the most you can tilt the engine
i think thats why my carb leeks because i got it in backwords
Floater 😂 wow
It sounds more like you are trying to teach yourself about carburetors for a test....lol
What’s the part and purple again LOL whatever all over the place the scription #NerdTriesToExplainPartOfEngineLOL
huh?
My motorbike dont strat
You need a better speaker I can't hear what you're saying
OK, for the rest of you, Matt has LOST IT!
At 9 minutes or so, let me correct.
That lower chamber, is the "float chamber."
Called so, because it has the "float" in it.
(Not the floater.)
The device works surprisingly like a similar
device in your bathroom. Your toilet!
Both have a chamber, a float (not a floater
ask Eddie Murphy and Hugh Hefner about
a floater) and a shut-off valve.
Oh, the "floater" doesn't push down. (10:45
or so) that would be a "sinker." the float,
since it floats, (that is why they call it a "float")
floats, and slows or shuts off the fuel flow.
Matt, 15:55, SERIOUSLY!
Talk to some Mechanics! They (we) work on
this stuff. You've NEVER gotten your manicured
fingers dirty! Your ignorance, (and ALL of BikeBerry's
is showing!
BikeBerry, PLEASE keep posting this garbage,
because I can "hit it out of the park" while drunk!
steve
Steve Skouson what about if yall mechanics stop yelling at comments and start a fcking good stuff channel where you guys can gain money and good people-viewers could really learn to set up things good...
This is good information nevertheless because he did not use the correct technical names dont mean he is ignorant we all know what he ment wise ass
thanks it was very helpful but you seriously could make this much shorter, it would have been more interesting
These people are pure liars. Would never buy from Bike Berry again

Bigger question is do you know how a carburetor works.that was 20 minutes of non sence

the part in blue is the air filter the part in green is the slide the part in purple is the float bowl. if your going to make a video to educate people make sure your educated first
Duhh Derrr Where do the muffler barings go duhh derr me just pawn in game of life.. derrr.. You fairy fart smeller.. Duhhh derr wood
The muffler bearings are mounted next to the blinker fluid resovior..
Jesus wept, lol. I appreciate your attempt to explain carbs, but your "I'm gonna ad lib it" approach is, honestly, awful. Write a script! Use it! You need to use STANDARD NOMENCLATURE for the components. That will allow the entirely ignorant noob to relate your effort to written references, parts lists, and manuals. Figure out the similes you can use that relate to common as dirt items that even the dopiest among us can relate to. Don't forget the actual "target ratios" that are needed for a gas motor of any type to actually run, lol. If I had no clue going in, this vid would only confuse me more, and possibly convince me it was a subject far beyond my ability to comprehend. That equals your company losing my biz, which I'm fairly confident isn't the goal you had in mind. The better you inform your target audience, the better the chance they will become satisfied repeat customers. That goal is entirely missed, I'm sorry to say.
Sorry to hear you had trouble following along. Please give us a call at (800)317-0479 if you have any questions on carburetors or need help making a purchase. We hope to earn your business.
