So many videos so much confusion , well until I got here . Thanks so much for taking the time to do this , it's much appreciated.

[@stevewoodbridge5648]

I’ve watched lots of videos on tuning and balancing SU carbs. This is the best by far. Really easy to understand and also being told WHY something happens when you turn a screw or something. Well done!!❤😊

[@WantCoffee99]

This is one of the best videos I have seen on any automotive maintenance or repair, and I've seen a lot of 'em. I have a 1963 544 that I am trying to do this exact thing to. Thank you for being thorough, I can't tell you how helpful this video is.

[@anthonysuozzo1228]

Dylan, Excellent video and nicely done. One comment. You may want to mention that when synchronizing the carburetors to get the same flow through each one, you should ensure the throttle shafts are not connected together. The throttle shafts should operate independently for this adjustment and then get locked to each other again when competed.....Tony

[@BET4FISH]

Thank you so much for this video. I found it extremely helpful and my 544 is running better than ever!

[@pauloisidoro2]

Thank you Dylan , we need guys like you , outstanding tuition and not bullshit. Straight to the point.thank you again

[@glennbrandimarte61]

Excellent video. The best ever on these simple but tricky little English (backwards-Whitworth- carbon-clutch-bearing-lever-shocks) carbs. You can probably tell I'm not a big fan of the way the Brits made their cars, but your video is a 10.

[@guitarTennisCarHomeFixFlying]

Worldwide auto parts of Madison rebuilds the Armstrong lever shock that seals the oil inside so you never have to add oil ,on KZbin I think that KZbin is titled Armstrong lever shocks guys working on a green MG and it's got a good explanation I ordered some from my car and they helped a lot As my car was bouncing around as I went over man hole covers

[@maintayne]

Great video with a super clear and helpful explanation of the cleaning and tuning process. Now I'm excited to try this on my MG!

[@hittman1222]

Thank you for posting this video. I have been tinkering with my SU's for a little while and this really helped me better understand how they work.

[@andrewhochstetter4542]

Thank you for posting this Dylan. Big help to a new TR6 owner!

[@MexicaliBenchmark]

I love you man, i am restoring a datsun 260z and you help me a lot with this video. the carbs were running very rich. thanks a lot!

[@bobdefalco]

Did this tonight - REALLY appreciate your work!!!!

[@foreigner2thisworld]

GREAT video!!! Thanks for taking the time and effort to explain so clearly. Can't wait to try it with my '66 Spitfire!

[@johnsalla3353]

Thanks so much for the video. I am considering switching from a zenith stromberg 150 carb to twin SU H4s. Your video was very help. Are you a Professor? If you are not, you should be. You were clear, easy to understand, logical, and explained everything completely. I have watched many KZbin instructional videos and your video is clearly one of the best. Before I watched your video, I knew nothing about SU carbs. Now that I watched your video, I feel confident that I could tune them. You helped make my decision easier. I appreciate your time and effort!

[@stefmaster1]

Excellent video. I have SUs on a 62 TR3B that need this treatment. Very informative. Thanks, Man!

[@felicealketti1534]

Best video for setting up the SU's. Thank you and hello from Germany :)

[@PB-mf3li]

I brought back to life my Datsun. Thank you!

[@stevenbauer7744]

Great Video. I've been playing with these on my Z's for the last 30 years. The screw in piston damper used in the Hitachi SU clones have two grooves cut in the shaft just above the brass piston. The grooves are low and high marks for the damper oil and can be used just like a dipstick to get the oil level correct. If you have too much oil, you can wipe off the damper and re-insert it a couple of times to get the oil level correct. I haven't looked at a European SU's to verify that the same grooves are there.

[@gemcity7973]

Brilliant sir, this is perfectly straightforward regular guy talk.

[@TheBgasior]

Awesome video! As a new owner of an MG Midget, this video will help as I thinker my through the needed adjustments. Thanks!!

[@jasonphilip4545]

Excellent video... thanks for taking the time to do this. Very informative.

[@bradmorgan911]

Great video. Very informative. I feel comfortable tackling my SU carbs now!

[@cbstrdst4892]

Working on a TR6 fitted with SUs tomorrow and really looking forward to it now. Great vid man.

[@highwatercircutrider]

I love this video, you are an excellent teacher! I have a 1971 MG Midget SU carbs......thanks, Gary

[@seekingmoby7198]

Great video. I'm new to su carbs and I'm about to reassemble mine for a '61 triumph tr3. These tips will help tremendously

[@motoringon]

Dylan, thanks for a super video. This really helped in removing the mystery out of cleaning and adjusting carbs! Fantastic Job! Please upload more videos. Cheers!

[@AllThingsAlex]

Thanks for this. Followed this tutorial to the letter, having just fitted a reconditioned HS4 on my Austin. Worked a treat! :)

[@Marcquinho2]

Great Video and very informative I'm new to SU carbs and my 71 240z is going to be happy that I know how to tune it. Thanks for the Vid

[@ytNACE]

This was a very useful video to translate all the reference material (in writing/books) to how to actually accomplish the adjustments. THANKS !!!

[@b4urthemasters]

Hey thanks for the great videos, also wanted to note, I used the procedure on an '57 mga (for people searching for mg), so this technique works for basically any SU carburetor equipped car. same goes for the valve adjustment video, thx again

[@Carl559969]

Dylan, a really useful and informative post. Many thanks. More videos please!!!

[@fransterhorst3694]

Awesome helpful video, thanks man! so much better than reading through the manual getting nowhere.

[@honnse1]

Thank you Dylan!!! My spitfire loves you !!! Greeting from austria (Europe)

[@TurtleGarage]

Hey Dylan, I know we've talked a little on the Volvo Amazon group on FB, but I just wanted to say thanks a lot for posting this video. I was a bit scared of tinkering with carbs as I had never done such a thing before but you explained things quite clearly and it was really easy for a novice like me to get my engine ticking over nicely. Thanks a lot man!

Replacing the single ZS on my Spitfire with dual HS4s. Very helpful video, thank you.

[@johncouch9359]

Great step by step instructions with examples. Thanks for making the video.

[@geneowens1586]

Hey Dylan! You and I are neighbors :D Just watched this and you pretty much demystified SU carb adjustments. Thank you much!

[@raleighgeddings8688]

nice yes that carb cleaner makes a difference bout every 6 months i do that and now my 68 1800s is not performing like it should. the peddle goes 90% to the floor before carbs activate. i notice the linkage is loose a little and its really taking a long time to get up to speed. I have to have the accelerator pressed to the floor, which is only around 60. all cylinders at 124-125 psi. my linkage seems off. any thoughts?

[@beegee22]

Very clear demonstration all the way through! Thanks!

[@nalinfernando8093]

Excellent video and great presentation. Love the tips too. Keep making more videos. All the best 😀

[@thenoobletlego]

Super useful tutorial, Dylan! I had no idea so much power was hiding in the L24 of my 240z, all thanks to your video! Thanks!

[@DylanBerichon]

Todd Martin Glad my video could help you with your Datsun. In addition to my old Volvos, I have an old Datsun 720. If only it had SUs!

[@laurensputseys9764]

Thank you for this excellent video. Just the one I need to tune my SU's!

[@Christopher28fair]

I have a 59 TR3, I've had to fight it EVERY time I wanted to drive it, probably used 8 or 9 cans of ether to get it running, over the last 10 years. Today I followed your instructions and it started right up, ran strong, - one happy car.

[@DylanBerichon]

Christopher28fair Awesome! So glad to hear your car is running well!

[@synergist4623]

Did they still make those in 59? I had two in 67-68 Don't know what year they were made, but my brother had a newer TR4. Wow i never thought that he would actually purchase a functioning car.

[@craigabarrett]

This was incredibly helpful. Thank you so much.

[@sric9995]

Great video. Followed these steps for my hs2 carb. Sweet as a nut now. Thank you.

[@adamcollier3722]

Great video, many thanks. SUs explained in a practical and easy to understand way :-)

[@technojaa]

Will use all your tips and tricks on a TR7! Thanks!

[@mrblowhard2u]

I have duel HIF-SU's on my '73 MGB and I use 20/50 oil in the dash pots, which works just fine.

[@mikegordon2840]

Good video I have a 1980 mgb le with su carbs can’t wait to tune them.

[@jamich5]

Thanks for the video, have always had some else do my carbs, but no more.

[@Bodgemiester]

Superb video, honestly , thanks. My TR7 loves you

[@Likethetacosauce]

all I have to say is thank you! I just purchased a 260z and needed this info as this is my first carb'd car.

[@Likethetacosauce]

+Rick S yup its my first carb'd car, it's not my fault I was born into a later generation.

[@Likethetacosauce]

+Rick S but I must say there are a lot less wires to worry about

[@MrFakerevolution]

Just one addition here. Instead of ATF, you should use S.A.E. 20 oil for piston damping. Manufacturer says so.

[@matttaylor377]

DYLAN MY FIRST CAR WAS A 60 544 NOW I HAVE A 68 122 WAGON GUESS I GOT THE BUG FROM MY FATHER WEVE HAD AT LEAST 15 - 20 122S AND 544S I HAVE A SHOP FULL OF VOLVO PARTS LOVE THE IPD SHIRT THE WAGON HAS A WEBER PROGRESSIVE ON IT NOW BUT I CLEANED A SET OF STROMBERGS UP AND INTEND TO MOUNT THEM REALLLY SOON REALLY ENJOYED VIDEO THANKS LEARNED A FEW THINGS I DIDNT KNOW

[@gordonwilliam9907]

Excellent video. I just bought a 1964 544 and was worried about setting the carbs. Thanks

[@wilberbottomwood152]

Great video simple explanation, thanks for helping us out.

[@amycyclenut]

Thank you, this was excellent information!

[@callumtbjones]

This makes so much sense. Awesome

[@henriquesilveira9261]

Thanks for the tips, i live in Brazil and here we had in the 70' the Dodge Polara and it uses a SU carb, i will buy one, now i will know how to adjust the carburator thanks

[@kcirful]

Very good walk through. Thanks!

[@Outlaw53james]

Thanks for the great video. I'm ready to tackle my 1800S now...

[@klockarmatspetercarlsson4085]

Dylan .. good video . No nonsens ✌️Greetings from a Volvo amazon & PV ovener in Sweden . 🇸🇪

[@southernman9397]

Dylan, good video but maybe I can set straight a couple of myths. Firstly, the pistons are not damped to prevent "flutter." They don't flutter. Check out a slide type carb on an old BMW or Italian bike. No oil and damper, and no flutter. Secondly, do not run ATF or anything but 20W fork or SAE 20W-50 oil. That oil and damper tamps down the piston upon acceleration and enrichens the mixture. Put in lighter oil and you're running lean on acceleration. Please keep up the great work.

[@NickL951]

I've run Mystery Oil in my z's for years, never had a problem.

[@rasmusandersen3520]

Really interesseting to view your videos. My P1800S is going to love this treatment :)

[@2541968joey]

Great video, well done. If you think working on 2 SUs is fun, just think what you can do with 3 HD8s SUs like I have on my XKE. Thanks for the tips & suggestions. I run 20wt engine oil in my carbs.

[@MarkJohnson-hw3gi]

Nice job with the video! Very helpful

[@sj122s]

great video... thanks for posting!

[@chandlersgarage]

Excellent video !!!

[@johnobiro5202]

Very nicely explained. Thank you.

[@MartinSage]

I used 2 things to balance my duel carbs. First a vacuum meter to ballpark things and then a rubber tube to listen to the hiss to fine tune. To test your mixture setting drive 55-60 for a flat mile, kill the engine, pull a plug and see that it's light tan. Where did I learn this? Gene Berg

[@ricardocanseco4860]

Awesome video man!!!!

[@edkennedy6120]

nicely done, very well explained

[@big800wildcat]

ATF is too thin for the dashpot oil. It will rev quicker in neutral but in gear under load it will cause a leaner mixture right when you want it richer for more power. Using it will lean the intended mixture during acceleration under load because it will reduce the lag time of the piston rising. The piston will then rise faster which will reduce the amount of vacuum acting on drawing the fuel up the jet. I'm not recommending SU's oil, but I'd suggest using something with the same viscosity. Leanness under acceleration load is usually not a wise practice for engine longevity, let alone best acceleration.

[@NICO418322]

Awesome video! Thank you!

[@uncleben2149]

Exceptional mate , thank you

[@matt787]

Thanks for the video it was really helpful, my bowls were full of gunk and lines were clogged. Gave them a real good cleaning, After I installed them back on the car was idling extremely high as if someone were stepping on the gas. and when I would push on gas pedal it was kind of sputter. I noticed some smoking from the exhaust manifold. Any idea why it would be idling that high?

[@jtab2110]

Great video, i have been terrified of messing with the twin SU's on my rover V8. Im now confident that i can at least take them apart and clean them to see if that helps performance. I have a sticking float on one of them and it over flows could you perhaps do a video of to fix that? Many Thanks

[@chrisp7921]

Hi, 240z here, will try this monday, looks straight forward enough. i'll let you know

[@andypaine7489]

Great video, thanks!

[@lee1778730]

awesome video!!! very detailed!

[@robwells5753]

Thanks for the video mate 🍺

[@keewaydin33]

Excellent explaination

[@watahyahknow]

i use one of those magnetic dishes to keep the parts in it holds those tiny screwws in perfect even if you happen to knock it of the fender as for filling the accelleration bit with the oil , there these oilcans pump thingies used to oil steamengines and other mecanical stuff , they pump luttle squirts and the perfect for filling these up

[@jasondean6979]

great video!!!!

[@johnlangsdorff382]

awesome !!, thank you so much, very well explained !!

[@brianhannon4075]

Hey Dylan, great video. My carbs running very rich, before I can tune, as per your video, my chokes appear both to be stuck. I see the linage, cables, etc. but, looking for advice to free them up. Any advice would be great.

[@petermai4663]

you are my hear thanks a lot for your very good video which helps a lot :-) greetings from Bavaria Germany

[@farveree]

Many thanks, clear and concise. I just need to get the gauge so I can do the twin SU's on my Bond Equipe . Thanks (Ady UK )

Like it , so next step for me as a Swede in Portugal is to tune in my Carburetors on my P1800 ! But.. it the feathers important so i need to change ?

[@neilhudson2377]

Hi Dylan, i have a reliant robin trike and i have turned up the mixture adjustment as far as it will go on my su carb but its still running rich. Pls advise

[@mrhoogy3150]

very clear, cheers!

[@FlyingTreg]

Very nice video. Thanks a lot.

[@adamvanshing]

Great detailed vid! Wish you could teach everything I want to learn =)

[@timid0234]

Appreciate the video mate helped heaps

[@coletrain2011]

Very good. Thank you!

[@LakesideVolleyBall]

Hi, thanks for vid, very helpful. I am about to check my Triple Su's on 66 MKx Jag, will it be the same process?

[@richardswithenbank7015]

Dylan, Great video maybe you could help me. For some reason my car conked out the other day and now it won't start and I suspect it's fuel ( su carbs) related. I have fuel in the float chambers but not sure if I am getting any in the carb itself, with the air filter removed should I be able to see petrol mist when trying to start? Any help would be good

[@brewster46]

Thanks Dylan.. nice video but big question.. should i first disconnect the linkage between the two carbs on my TR3 before i adjust the idle screw? (also pls wear gloves for your safety).

[@billtunis686]

awesome great work.....thanks
