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.

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

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.

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 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

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.

A great video! One question: At 20:45 I thought you could only do that (syncro both carbs with te speedscrews ) with the clamping bolds, on the shaft that connects both butterflies, LOOSE! Yours are still connected..you pull the central lever up and BOTH carbs react; can’t syncro like that??? Or am I missing something??? Ok, idle is set, then, right. But when you add gass, then they are NOT syncronised.
@DylanBerichon
@DylanBerichon 5 жыл бұрын
I don't really see a need to disconnect anything when adjusting the idle unless things are way out of wack. I'd rather make adjustments while everything is hooked up; what you change on one carb will impact on the other after all. As long as both butterflies open at the same time, it won't matter.

Hi Dylan, Nice video!! One question here. When you were synchronizing the carbs so the air through each carb would be the same, I didn't note that you disconnected the carburetors from each other. What I mean is, why didn't you have to loosen the connecting clamp that ties the two throttle shafts together? On my car, they mention loosening that clamp that holds the shafts tied together and then make the synchronization adjustment. After your all synchronized, you tighten up the shaft clamps again. Does this make sense?

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.

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.

Absolutely not unless you are going to port the head, raise the compression , change the cam to a 260/270. Even then, the engine was designed for SU carbs and the SU carbs were designed for that engine. You may want to change the needles.. Contact Moss Motors for suggestions. And has been mentioned, carbs are the last thing you want to address after, points, plugs, condensor, rotors, plug wires, caps, adjusting the valves, setting the timing. SU carbs are trouble free, easy to adjust, need little maintenance.. unlike Webbers. Expensive and unnecessary. And then join MGEXP discussion group.. As a former BMC (factory authorized Rolls, Bentley, Jag, Aston Martin, Austin, MG, Morris, Lotus etc dealership ) mechanic in the 60s and 70s..., and prior workd for SCANDIA Motors in Seaside Calif , the official Volvo SAAB dealership. the biggest problem with SU carbs are the geniuses who think they need adjusting and they are the chosen ones to do so, especially independent garages and your best buddy who used to own an MG. Also do a youtube search for University Motors LTD , all about MG cars and SU carbs.

Check for vacuum leaks on the manifold and any piping running to things like brake boosters, stuffed vac advance etc. You also need to make sure everything else is spot on with ignition (points, dizzy cap, rotor button, condenser, plugs and leads), timing (Including checking the vac advance and mechanical advance), tappet clearances, compression etc before you go near the carbs. They are the last thing to look at in a tune up, but often missed. Good luck. 👍

I am sure that you have a vacuum leak. When there is a air leak in the intake manifold, you can never set up your carbs. One way to find the leak is to spray carb cleaner onto different locations on the intake manifold and river piping. Another way is to use an unlit blow torch and aim the nozzles at different locations including all the rubber pipes. When the engine speeds up while gassing a location, that is where the vacuum leak is located!

Hello Dylan, I hope you are ok. First of all thank you very much for this tutorial, it’s great! It encourage me to clean my carburetor! I own a Mini 998cc and the problem was that jet was not returning (when releasing the choke). When I got there.. I found that my car has a HS4 waxstat carb (which I don’t know if needs a different procedure). I took out the carb, clean everything from the dirt stuck and reassembled. All moves right now. I followed the video. I flushed the jet and gave 12 flats down. The problem I have is that when I lift the piston (by using the pin) to check if mixture is ok, the engine stops. If I understood correctly that means that mixture is too lean! So I gave 1 more flat down.. then another, another and another.. and the car always stops. Any idea? Thanks in advance!! Regards.

I have a 1971 Datsun 240Z and I am working on the SU carbs. I use to have this down pat, but it's been w while, and the car has sat for some time now. I have taken them completely apart, and cleaned every thing, but I am having a few issues. 1. For some reason both chocks work ok when out, but sticking when installed.2. The jet in the rear sticks a bit when all most closed, 3. For some reason the carbs are being difficult to ballance, what do you suggest as a Base Line Setting for the Throttle Adjusting screws? If you balance the carbs with the Throttle adj. screws, what is the Balance screw for?
@DylanBerichon
@DylanBerichon 6 жыл бұрын
Hello! Sounds to me like your jets aren't centered. There is a special tool that can do this, but there are other ways to get around not having the tool. There is probably some crud / rust / dirt inside of the Jet that is not allowing them to move freely, or a spring that is no longer holding tension. As far as the base setting, use your best judgement. If the idle bounces around or changes for seemingly no reason, you might have throttle shafts that are worn out. Spray around the intake and base of the carbs with water and see if it impacts the idle. If it does, you've got an air leak somewhere.

An otherwise stock Volvo B18 engine would use ZH needles. Your flat settings will vary. 12 flats is just a starting point. Many different factors can have an impact on mixture. If you are in a higher elevation area where the air is thinner, you might need to run the carbs a fair bit leaner. Find out if the car is running too rich or too lean, and adjust appropriately.

Great video looks easy too! What would cause my idle to rise after car has been run for awhile? Typically it will idle at 1200 rpm when it first starts up then, after the car has been driven it will rise up to 2000rpm which is too fast. What causes this rise in rpm and what do you think is the cause? Thanks!

You've got an air leak somewhere. Probably at the throttle shafts.

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?
@DylanBerichon

+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!

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

Historically after letting car sit way too long, 10yrs plus, we got it running again, and painted up, the carb would start running rough(rich) and I would lean it via the nut underneath the card. main complaint now is it idles real high(tach doesn't wk, not sure if that caused by using pertronix ignition but seems like I had tach after putting in petronix) and 2nd complaint, the car won't to diesal or keep running sometimes when I turn it off. Time to no doubt to follow your intructions or at least tighten adjusting nuts a bit. I rebuilt carbs b4 it sat so long, that another option

Would the tunning of your carbs have anything to do with cold starting issues?

Absolutely. I didn't go over it in this video, but make sure your choke is working correctly. With the choke pulled out all the way, the jets should drop down all as far as they can go, and it should engage a cam to increase the idle. Have a look there if you haven't already.

Dylan Berichon when the choke is pulled out and it has been thoroughly warmed up it will idle, would that point to adding more fuel to the mixture?

Dylan, when setting the idle, do you not use the tachometer to set the idle??
@DylanBerichon
@DylanBerichon 7 жыл бұрын
I'm sure one could use a tach to get the idle to an exact setting, but I just set the idle by ear. Idle will shift ever so slightly on a carb'd car anyway (depending on a variety of different factors beyond your control), so as long as you're in the ball park you should be good.
