Many people have posted comments asking about the sync tool I used. It's available from IPD at this link: www.ipdusa.com/products/5517/... - Авто та транспорт
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.
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!!❤😊
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.
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
Thank you so much for this video. I found it extremely helpful and my 544 is running better than ever!
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.
Worldwide auto parts of Madison rebuilds the Armstrong lever shock that seals the oil inside so you never have to add oil ,on UA-cam I think that UA-cam 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
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 UA-cam 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!
Thank you Dylan , we need guys like you , outstanding tuition and not bullshit. Straight to the point.thank you again
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.
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!
GREAT video!!! Thanks for taking the time and effort to explain so clearly. Can't wait to try it with my '66 Spitfire!
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.
Working on a TR6 fitted with SUs tomorrow and really looking forward to it now. Great vid man.
Thank you for posting this Dylan. Big help to a new TR6 owner!
I love this video, you are an excellent teacher! I have a 1971 MG Midget SU carbs......thanks, Gary
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!
Thanks for this. Followed this tutorial to the letter, having just fitted a reconditioned HS4 on my Austin. Worked a treat! :)
Great video. Very informative. I feel comfortable tackling my SU carbs now!
Thank you Dylan!!!
My spitfire loves you !!!
Greeting from austria (Europe)
I have duel HIF-SU's on my '73 MGB and I use 20/50 oil in the dash pots, which works just fine.
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
Hey Dylan! You and I are neighbors :D Just watched this and you pretty much demystified SU carb adjustments. Thank you much!
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?
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.
Christopher28fair Awesome! So glad to hear your car is running well!
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.
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!
Did this tonight - REALLY appreciate your work!!!!
I brought back to life my Datsun. Thank you!
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
Excellent video... thanks for taking the time to do this. Very informative.
Awesome video! As a new owner of an MG Midget, this video will help as I thinker my through the needed adjustments. Thanks!!
Dylan, a really useful and informative post. Many thanks. More videos please!!!
Replacing the single ZS on my Spitfire with dual HS4s. Very helpful video, thank you.
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!
Turtle Garage and
Excellent video. I have SUs on a 62 TR3B that need this treatment. Very informative. Thanks, Man!
This was a very useful video to translate all the reference material (in writing/books) to how to actually accomplish the adjustments. THANKS !!!
Best video for setting up the SU's. Thank you and hello from Germany :)
Brilliant sir, this is perfectly straightforward regular guy talk.
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
Great video. Followed these steps for my hs2 carb. Sweet as a nut now.
Thank you.
Thanks for the video, have always had some else do my carbs, but no more.
Will use all your tips and tricks on a TR7! Thanks!
Thank you for this excellent video. Just the one I need to tune my SU's!
Great step by step instructions with examples. Thanks for making the video.
This was incredibly helpful. Thank you so much.
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!
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!
Excellent video and great presentation. Love the tips too.
Keep making more videos. All the best 😀
Awesome helpful video, thanks man! so much better than reading through the manual getting nowhere.
Just one addition here. Instead of ATF, you should use S.A.E. 20 oil for piston damping. Manufacturer says so.
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.
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
Great video, many thanks. SUs explained in a practical and easy to understand way :-)
Thank you, this was excellent information!
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
Very clear demonstration all the way through! Thanks!
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.
I've run Mystery Oil in my z's for years, never had a problem.
Excellent video. I just bought a 1964 544 and was worried about setting the carbs. Thanks
Thanks for the great video. I'm ready to tackle my 1800S now...
Superb video, honestly , thanks. My TR7 loves you
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?
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
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
Dylan .. good video . No nonsens ✌️Greetings from a Volvo amazon & PV ovener in Sweden . 🇸🇪
Great video simple explanation, thanks for helping us out.
Good video I have a 1980 mgb le with su carbs can’t wait to tune them.
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.
+Rick S yup its my first carb'd car, it's not my fault I was born into a later generation.
+Rick S but I must say there are a lot less wires to worry about
Very good walk through. Thanks!
Really interesseting to view your videos. My P1800S is going to love this treatment :)
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.
great video... thanks for posting!
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?
This makes so much sense. Awesome
Twin SU's demystified - can it be possible? Excellent video - no BS - just sound tips.
Still referring back to this vid 2 years on. My mates think I'm an SU wizard. Done quite a few of theirs. Cheers Dylan.
veeg good video I bought an Suzuki SJ413 today with a horrendous flat spot and was absolutely stumped on how to adjust it. I can't wait to crack on with the adjustments tommorow after watching this thanks for such a good video!! If you have any more good tips on how to set the idle on a single carbed vehicle please share!!!
ua-cam.com/video/Y9t8XhFlKbk/v-deo.html Maybe invest in this 'Old School' Tool
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
Nice job with the video! Very helpful
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.
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
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 )
farve
Great instructions!! I'll try to repair my Daimler SP250 like this))
you are my hear thanks a lot for your very good video which helps a lot :-) greetings from Bavaria Germany
Excellent video !!!
Thank you so much lol. No one will work on my SU’s so now I feel a lot better about tackling them myself.
How do I know if I need a full rebuild, or just a clean and adjustment ?
Hi
Have you checked the throttle shafts for sideways movement?
nicely done, very well explained
Hi, 240z here, will try this monday, looks straight forward enough. i'll let you know
Great Video! I am having a problem with my MGB - black smoke backfire - I will check the mix and comment back - thanks for the video
You are probably running rich
Do you think you can show a video how to replace and install a starter? I juat bought a rebuilt ine from your ipd website and i camt take off the lower bolts since the slave cylimder is in the way
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
Awesome video! Thank you!
Fantastic video! Going to be working on this as soon as I get new dashpot springs. I have these on a 1967 Rolls Royce. There is no easy way to get at the intake of the carburetor without removing the whole intake and choke. Is there another way you'd recommend setting fuel air mix? My black exhaust tells me I need to work on it a touch. Thanks!
Also, on further inspection, I can NOT find a way to get at the mix adjustment on the bottom. I have a V8 in the way
Thank's Dylan, from 18:30 very interesting, Ihave now an excuse to check again my TR4A... :-)
Very nicely explained. Thank you.
Very clear instructions. Perfect video editing. I have a volvo 122 with the same carbs. My wife was following me and she said that the car smelled a lot of exhaust. Do you think the car is running rich or to lean?
+mportklr It's probably running too rich, but no matter what you do, the car will always smell of exhaust for anyone behind you. It's certainly not a modern car in that respect!
+Dylan Berichon when I get the car running I will do this SU Carb setting. Thanks for the reply.
Awesome video man!!!!
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).
Great video, thanks!
Great detailed vid! Wish you could teach everything I want to learn =)
awesome !!, thank you so much, very well explained !!
Hello Dylon, i have a question, if s u stands for skinners union, what does DAF stand for, thank you in advance
Very nice video. Thanks a lot.
Hello i have a question i have motorcycle with hif38 carb on custom
manifold. Mine question is about the vacuum advance port should i block
it or keep it unblocked? there is nowhere for it to connect and it vacuums to air.
It sounds a little slappy on the valves. I used 5 weight oil in my carbs. Valves were 25 thousands cold- 26 hot. Idle @700. These engines always use solid lifters and were a bit noisy. Good video
