Lowbrow Customs - Amal Carburetor 101 & Throttle Cable Install. Overview, Disassembly & Basic Tuning 

These guy know what works, and works best. There tech department has sent me very useful information on my build. I appreciate it greatly.

I bought a set of these carbs for my Dads 78 T140v. He said the bike never ran correctly since new. It’s been rebuilt with the same stock carbs and never ran correctly after countless mechanics having their grubby hands all over the bike. Well I bought a set of these and the bike runs Amazing! Starts on the First or 2nd kick Everytime. These carbs are AMAZING. Thank you for selling these and making my Dads eyes and ears light up every time I start the bike and we go ride.

I am now an AMAL Carburetor expert... Me and my BSA A65 thank you!

rebuilding one of these for my bsa A10 during lockdown best tutorial your never too old to learn .

I have to say these Triumph/Amal videos from Lowbrow Customs really are excellent; so informative and easy to follow. Thanks so much for taking the time to make and upload them. Greetings from the UK! 😀👍🏻🏍✊🏻

As a newbie to these carbs (but having worked on SU types) Your Video is brilliant ! I am so glad I found it !! Bloody good info delivered in a relaxed manner with out annoying music! great Job! I have a T140v 1976 - now I am inspired to taclkle a twin set up Many thanks

Hi. Fitted the throttle cable today- and also took the carb apart and gave it a clean . Seems to work a dream- so thanks for the great video !

This is a great video - really well paced, with ample opportunity to see the things being discussed, and very knowledgable input. I'll be replacing the throttle cable on my A65 Thunderbolt this weekend , and the video is very helpful. Also great to see the carb taken apart and explained . Thank you. Lee (UK)

Thanks guys for the Triumph based videos! Just bought my 1st Triumph chopper and your parts, wiring diagrams, and video tutorials are a great resource!

Great video. Very well presented. Has helped me check over my 1967 Amal Concentric.

Really helpful thank you . I bought one of these for my 500 bullet and while having worked on bikes for many years your film reassured me of my knowledge .... really fantastic.... you helped a Brit feel ready to enter is workshop

Thumb's up from me. Thanks for taking the time to get this up here. What with all the elderly British iron I've nursed along over the years I could probably disassemble and reassemble a Concentric blindfolded, but I still enjoyed this and even learned a few things. Thanks again!

For the past 4 weeks, I was not able to fix my throttle cables....After watching your video... now I am sure I will get my bike running tomorrow

Excellent video. Helped me greatly with my 71 commando carbs.

What a well produced and informative video. Thanks so much for taking the time to make this. It is very helpful

Excellent video and very clear instruction, thankyou. Just what i needed to fit 3 Amals to my 74 Trident 750.

Thanx. This carb rebuild video enabled me to change out the EFI (safety logic sucks) on my Royal Enfield Classic Bullet 500, to an Amal carb with a kit from Hinckley's. Before I found this video, I had tried another one that caused me nuthin' but grief. After your instruction, it started up 1st try.

First class tutorial. Thank you.

Excellent video on the carb. I have a 69 Bonneville and now I know how to adjust and troubleshoot the carbs. Thank you!

Great Video very useful. Both my T140 carbs had the faults you describe.

Excellent!! Thank you Sir for such an excellent Tutorial, Many Thanks From Evan, Wanganui , New Zealand

Excellent '101'! Perfect for my custom '78 T140. Tks!

Well done! Thanks much it's a great review if you know and a great explanation if you don't ( or just forgot ), strong work!!

Boy it would be nice if you guys made a video using the pamphlet that comes with the carbs and explain its contents. I dont know if my brain goes to another planet when I see that thing but I need a tutorial on that pamphlet!

absolutely essential to get this right, cool tutorial todd,by a cool chap.thanks

Thanks for this I’ve just got Royal Enfield Pre 65 Trials and was trying to understand why it runs then stops again and again now I know appreciated

Great Video Todd , Had the same deal with my BSA cable now i know THANKS

Todd,you would make a brilliant teacher ,keep it up!!! See you later mate

This 'older dog' learned a few things here as my old Amal had been 'sticking'..so I took it apart and cleaned it good etc. but same problem. Sanded the slide and carb body to make it pretty decent but still sticking problem. Checked the cable and it's frayed and bent, soo. Been riding Triumph since 1970 but had a factory trained expert mechanic and friend doing the tedious stuff for me all those years so I could just 'ride.' Well, he passed away here in Rhode Island this year and is sorely missed; now, I have to learn to do stuff that I was too lazy to do myself or lacked confidence in..this is one much needed video for my '72 TR6. Just got a new throttle cable (didn't know there were two types of cable ends for the same part number or that the carb top could go in both directions!). Bike is otherwise in excellent shape (high output alternator, halogen headlight, Boyer ignition, hagon shocks) thanks to my old friend, but now it's time for my PTSD to be tested and try hard to concentrate! Thanks much, Todd, for this video..will keep your shop in mind in case I actually determine I need a new carb afterall.

I had to post this. I had popping from my port side exhaust. My fix was to pull idle mixture screw and squirt carb cleaner through til it came out front of carb. I couldnt believe it fixed it totally! Crack the throttle and she goes right off,no hesitating or pop!! Try easiest first right?

This is a fantastic illustration!

Great video! Thanks for taking the time to make a quality video!

Great video!

Such cool videos. Very instructive.

the pipe between the carbs used on duel carb applications, is so a tap can supply both carbs, and the other tap can be for reserve... good luck.

I've got one of those 50 year old carburetors on my 1971 Triumph and it runs like a dream. I've also got a pair on a 1972 Triumph and I'm having some problems with them.

Thanks Todd All good tips !

This guy is money 💰

Keep in mind the technique demonstrated for changing a jet with the bowl in place has to be accomplished with carburetor off the bike. If intending to change the jet with the carb mounted, you will have to remove the bowl in order to access the jet with a wrench. There's not enough room to remove the jet, through the access plug at the bottom, with the carb mounted on the engine.

I really enjoyed the video and the relaxed way you have shown us the way to strip the carb "But One very big piece of info you did not mention was regarding the (Banjo fuel pipe nut connection ) that if done wrong can cause one hell of a problem, if you look at the "nut" you'll see as shown on the video it has the hole were the fuel enters the carb from the fuel tank !!!!! Now if you do not make sure the Banjo nut's hole is in line with the fuel intake pipe !!!!! you will not get a full fuel supply, Tip mark your nut with a marker pen (or mark lightly with a hack saw) from the top to bottom of the nut when it is in line with the fuel pipe, by doing this you will always have a nice clean fuel supply through the Banjo if the line is in line top to bottom of the pipe inlet.

This professor is even a comedian hilarious don't let the metal giblets get into the carburetor you really don't want that in there LOL great video very insightful

Fantastic tutorial thanks

Excellent explanation.

Great video. Thank you 🙏

Absolutely excellent video. However, in interest of precision, the screws are PoziDriv and a PoziDriv screw driver should be used vs Phillips.

These videos are so cool! Thanks to all the staff at LBC! Any chance you could make one on how to setup and tune a 930 dual carb setup? Thank you again!

Great Vid Todd! I am about to get my first classic bike...'73 Commando. Will be needing to perform carb work to get her road worthy and this vid will be very helpful. The bike does use dual carbs and there is a cable splitter at the carb end. Can you cover how to properly balance such a dual carb setup? Thanks.

Needed more close ups....but thanks...I found fitting the barrel and spring on the bike hard to do...any more tils?

Hi great video would have been good if you had explained why you dispensed with the choke arrangement Amal fitted and maybe a short description on how the Carburettor works. i.e. Venturi etc.

Cool video Please do one for CV carb

really helpful, thanks!

Great video!!! Many thanks

Great info

Great educator!

Nice video can you do one for tuning the 389??

A great site.

Top tips👍 🏴󠁧󠁢󠁷󠁬󠁳󠁿 Wales uk.

you put it back together, did i miss how far to put the mixture and throttle stop screws in as a starting point?

Excellent, thanks.

random question could i install 2 of these on a 71 yamaha 650 i love the simplicity of the amal

Great video. I have recently acquired a '72 Bonneville T120R, and wondering how to determine which type of Amal carbs it has. Are the housings marked with the Series #, Model #, or some other markings? I understand your point early on in the video about rebuilding a 40-year-old carb, but are there any cases in which you might recommend an original rebuild rather than replacement? My Bonneville is original, and I'd like to keep it as original as possible. Thanks! BP

Nice video man. Thanks much. My new lightning appreciates it.

Fantastic 'how to' Thanks a lot :)

many thanks

On the pilot jet i hear that certain years you can't remove them ,they are not screwed in is that correct ?

Thanks I have one of these loosely assembled on a Ducati 250. Brilliant video which has made things a lot clearer. But what about the choke cable set up?

what size main jet is ideal for a single carb, dual manifold application on a 500 daytona?....how many turns out for the air fuel mixture and idle screw?...thanks kindly

Hi I am Kumar I have just fitted new carb ( Amal mk1 concentric 26mm) and pod filter looks same as one that picture above on my bike ( 1984 Royal Enfield 350cc ) I have few questions to ask if you don’t mind and I guess as you are using Amal carb you would be able to clarify my doubt my questions are followe 1 I don’t find any difference of using Amal carb as I was using mikarb before or Am I tuning is not right way? 2 I feel the throttle cable is just a bit hard to throttle after changed to Amal carb ( have been told by mech just because of the spring in the Amal carb is high tensed one than one was on mikarb 3 after changing the airfilter from the Indian made box type to Amal pod one which gives me ‘kisk’ ‘ kisk’ noise or is that normal with that sort of filter as I never used that before replies will be much appreciated thanks

I recently bought a '67 TR6 with an Amal 930. The bike was at sea level and I live at 3500'. Could you give me jetting and air screw suggestions

What are the best silencers to fit on a t120 for that super sound mine sounds like an old tractor and is the balance pipe necessary Happy days

Hello sir, i just fitted an amal 376 carburettor. After kick starting, the motorcycle went into high idling. It sounded like it does when we pull back on full throttle. Is it because i of the throttle cable? Please guide.

Just purchased a 1974 T140 Bonny and am rebuilding the carbs. Loved this video but have a question about why you remove the choke? I live in Washington State where it’s a bit cold in the am , will the bike still start in cold weather without the choke?

Just purchased a barn Find 1972 Triumph Bonneville T - 120 and it has these Amal carburetors on them. In your video it says that if there is two Amal carburetors on that you should put it so that there's a plunger type deal on the sides of the carburetor. The one I bought has one on the left side of the engine but not on the right side. Should I make sure that both are the same carburetor?

How are you starting your bike with out the choke

If you're using the choke do you have to drill out that hole on the top as well?

Just bought a set of carb’s a year ago. Hasn’t been on the road yet, but just wondering. One of the ticklers is leaking constant fuel out the hole. Any suggestions.

Super duper. Would love to see a set up for dual carbs with the splitters. Do new cables exist for splitters?

Hello sir, i have installed a monobloc 376 on my royal enfield 1968. The problem is it is emitting black smoke from the exhaust and also, when i increase the rev/throttle, it does not go into high idle. Please advice. I am unable to find any solution. Thankyou :)

Great how to video as im new to amal carbs just wondering why the the choke components were removed .

nice video

Would this carb work good on a honda 500cc engine yes i understand its not factory it would be for a custom job finding factory carbs are really expensive

Brilliant

I didn't see the Clip - throttle needle, being placed into the carbureator, it was already inside the carbureator body during the video. I saw the Throttle needle being dropped into the carbureator, but didn't see where it was attached to the clip. Without the throttle needle being attached to the clip wouldn't it be loose inside the carbureator...?

Thanks.

Did some jb weld work on my Fischer Amal 24mm for my puch 175. The bottom bolt had stripped and was leaking. Bike starts now but won't run without full throttle or pushing the tickler Petcock is working as I took tube off and fuel is flowing Maybe time to throw in the hat and get a modern mikuni but something that looks cool. Also how do modern carbs hook onto these old bikes. I need a 24mm to mount to my puch 175

Great video. Question: How can you tell that you have a carb that is worn enough to need a new replacement? I get the part about over-tightened screw distorting the shape of the carb body, and the slide sticking because that part is no longer round. Anything else that I should look for?

Anybody knows old carburator's which named Galery?

one thing that i'm curious about, is the 3rd adjustment screw. You have the idle screw and mix screw on one side, but there's another screw on the other side (inside). Its a phillips head instead of the other 2 being flat head

Do you also have the Mk iv carb?

cool personality. this guy is a walking encyclopedia of moto.

Well done Todd, you will now be known as Sir Todd of toddington

I have a Mk1 Amal carb on my Bantam Trials bike. This is an excellent video as these carbs are new to me. However, why remove the choke? The air slide has been removed on mine also but I'd like to know why?

Has anybody used the amel carbs on 80"ulh feed. Back

Brilliant tutorial Todd 👍🏼 I do have one question......... why do you not put a choke in for your own custom builds🤔🤔

Hey Todd is what is the default position for the throttle stop screw and the pilot air screw?

Hey Todd what is your favorite year bonnieville and why ? I live in Boston and have been looking for a mostly complete bike that has a title to restore myself and ride , any leads out my way ? I kind of like the newer brakes .

What’s the best way to fix a sticky tickler?

you didn't explain why you eliminate the choke system from the new carb

Beware of sticking slides particularly on new ones

I'm getting my 71 T120R back to where I can ride it again after over 10 years. The previous owner put on an intake for a TR6 so it only uses one carburetor. Will this be a problem. I have a new Amal. The previous own had a Mikuni carburetor on it. I still have it. I've owned this bike for about 20 years and haven't made road worthy since I bought it. It has a bolt on hard tail and a Girder front end. I would love to get it road worth for bike nights and show.s The motor is mounted on a 1965 frame. I've saved this video.
