A couple of things I would recommend :
Hook a vacuum gauge on the carbs and tune them for maximum vacuum. Also be sure to verify that they’re synched properly, they sell a special synchro tool for the webers
Being that it’s a small engine and those are huge carbs, I’d check your jets to see how much smaller you’ll have to go. It sounds like it’s running way too fat, which would contribute significantly to the issue you’re having.
Triple check your base timing and your timing at full advance to verify the springs and weights inside the distributor are correct for your setup.
If all of these are good, I’d move on to the deeper troubleshooting like your distributor being set properly, cams in the right place, ignition box sending proper voltage, etc. I’m sure it’s something simple that you’ll be able to remedy without too much hassle. Enjoying all the content with this car, can’t wait to watch you have fun with it!
I agree looked super rich!
I would agree!
This guy carbs for sure.
iirc? The accelerator pump has a significant effect on how much bogging there is when stabbing the throttle. Of course, correct jetting first before messing with it.
+1 from an old school carb guy.
Honestly this is one of my favorite builds you’ve done, just for the fact it’s very different and very simple compared to your other builds! I love the other builds also but this one is just great in its own way
He needed the break from the overly tedious to just regular tedious.
It’s been fun to do a car that doesn’t have to perform perfectly and do something super well. Squeezing every ounce out of it. Just something for fun and pure smiles. Nice change of pace for sure.
Best part is it’s an actually obtainable build for normal people not able to spend 10s of thousands of dollars on a build.
Jimmy and Taylor building 86’s at the same time is so bomb!
Taylor building and 86 jimmy building a Honda 😂
The only way I keep the videos straight between the two of them is what side the ITBs are on 😂
you need a synchronizer tool to sync the vacuum on those 48s. Check the jetting it has as well. The bogging is the MSD box. 4AGE on webers with MSD like around 15 degrees of timing then you need to set your timing curve. Looks like you have a digital box with built in timing curve. once it hits 3000rpm it should put your overall timing at 30 degrees. Make sure you have your box set to 4 cylinder and make sure you dont have rev limit set too low on MSD box. If you have any questions feel free to message me. I have been running DCOE on my 16v for a long time.
If they’re 48s that’s way too big for a 1600cc, best to swap out for 40s
Good Info, but the msd box he has doesn’t have a timing curve at all
I love that both you and Jimmy are doing 86s at the same time, 2 totally different approaches, very fun to watch the differences. Keep it up taylor!
I feel like so many people now so used to just throwing it away and buying another one, when in fact a lot of times rebuilding/remaning like you did is just as good and supports a skilled tradesman! That is a dying breed right there man, shame.
With a proper regulator you can use stock fuelpump with carbs.
Yes you can but it puts a lot af strain on the pump
Yeah I’m hindsight I should have done that. But the fuel lines on the car were already mangled so it needed to be re worked anyway.
@@xandrae4205 I dont thing so. A turbo style regulator and return line is way to go.
Every time i eat, i watch Ur videos. Just wanted to say thanks for being urself and love all ur projects hope you have a great 2023
Neighbors like, "had to be a UA-camr" 🤣🤣 love the fact of having different cars for different experience!
I absolutely love this car. The old school technology is something I really love on this car. Keep it up as always Taylor
Your car isn’t revving past a certain rpm because you have no ignition advance anymore. Its just locked at base timing. You need to get a vacuum/mechanical advance distributor or program a timing ramp into the msd box (if that’s even something you can do)
you can run the stock ignition with no advance but you have to set it at the max timing you want i ran mine for years like that and it was fine taylor would need to get a msd 6 al-2 programable ignition box and write a timing curve in it
This
It is something that can be done on the msd 6530 but not the normal 6aL he has
Yep. I had the same setup 6al is trash you need the 6al2 like I bought and program it. Or use 4k dizzy with vacuum advance
@@user-kc8ps4jt4c it’s not trash it’s just not the right tool for this application haha. They work fine on a dizzy with an advance mechanism
ITB 2zz would be sweet in this thing
Jimmy Oaks Vs Taylor’s AE86 BATTLE!
Let’s see it!
They both look like stanced garbage.. stancing these cars looks so trash they look broken
@@theduder9548 I disagree
I believe they are both modded period correct and appropriate.
Seam rippers work great for cutting tape / loom and the ball end of it ensures you wont slice open any wires
@Greg Jenko For sure. I used to slide (very pointy) flush cut pliers to split looms open, specifically on Peterbilt harnesses, which are wrapped in what I call hockey tape. Very tough tape. I was inches from a spot in the wire that was shorting to ground, ended up "nicking" the wire with those pliers, and had to add a new section of wire to repair the already open spot of the wire, plus the section that I compromised. Never again!!
You should do a Short where you visit and give a quick tour of the alternator/starter repair place.
Taylor, it seems to me that the problem is when you go from the idle circuit onto the main circuit. It might be that the main circuit is too lean or completely blocked. Time to call Kevin for a chat. The 48 DCOE's seem too large to me, but If they've been fitted with the correct chokes and venturis, they will work. The fact they've been on an AG engine before is good. I've used 45DCOE's on a 1.6 litre motor, but that was a full race motor. Time to call Kevin for a chat. Personally, I would have hit up Duetsche work for a low pressure in-tank pump, & used bango fittings on the carbs, with a Tee style piece in the middle. This would have meant only one fuel hose, instead of two.As usual, this is just my opinion, I'm sure you'll get a handle on it.
You can do a lot better with the fuel lines to the carbs. They sell banjo fittings so you only need to run one fuel line. Great work. 👍
Super simple. It’s your dash clock. You fix that dash clock to the correct time and and it will run super smooth
All the guys I know with vintage carbed cars use an injection pump with a return line and a pressure regulator just before the carbs. That way they don't have fuel sitting in the line getting hot and messing up the AFR.
So many Keyboard Tuners in here. Pretty sure Taylor knows what he's doing. Lighten Up Nerds.
Carbs are a different ball game. Need to sync the carbs, adjust lean best idle and probably rejet the carbs to that engine combo. ... lots of carb experiance on these old VW's and running dual webers on most setups. You'll get it man!
This I'd why I love watching t-rays videos
the sounds this engine is putting out reminds me of my old 4 cylinder motor cycle engines that had the carbs out of sync or only firing on three cylinders this is why you have all of the smoke and i mean all of it
Your starter/alternator rebuild guy as soon as you said he was in a wheelchair I knew who you were talking about
First Jimmy O now yours. Gonna call this 86 Monday
Rule #1 with carbs, get your ignition timing right, then adjust the carbs
Those carbies are going to need mad turning man, I just watched Benny's Custom Works doing the same thing .. he found a bloke to help and the information he had was insane
After watching trotl montages all day today I’m sooo happy you don’t replay the same music over or time lapse over and over again 😊
It's been said by others, but this is by far my favourite build on the channel. The carbs, the 4AG, the pop-up headlights, big smile energy all around!
You need to check the cam timing and be confident that it's correct. First thing to do is balance the carbs, they are out of sync, once each Venturi is pulling the same airflow then set the idle mixture screws. There are lots of good Weber tuning material out there
Agreed they sound out of balance
I enjoy your jibber jabber because you explain things to us. I learn when you jibber jabber
Don’t forget coolant has a higher boiling point then straight water.
Love this build. Thanks for the videos.
distilled water is significantly better at heat transferring meaning it'll take much longer to heat soak the cooling system. while anti-freeze has a higher boiling point it tends to hold onto that heat causing higher cooling temps overall. both have their advantages and disadvantages. location, use, how hard you're going to run the engine, cooling capacity, etc all play a part in whats the better choice and if you don't know then just play it safe and run 50/50.
@@sirmonkey1985 The biggest difference is that he plans to drift this car most likely at drift tracks. Tracks won't let people run antifreeze in their cars because it's a pain in the ass to clean up if it does spill. Most tracks require 100% pure water only in the cooling system in all cars for any kind of competition event.
Back in the early 80’s my buddy picked up a first generation Celica Supra and I was obsessed them for years. Then interest’s changed and I went after American muscle now you got me thinking back on them. Thanks for the video and looking forward to seeing the next one.
When doing harness work like that buy a seam ripper like for sewing. Works awesome for cutting the tape and not worrying about cutting the harness. Use them all the time on harness with the mesh and they work awesome
I haven't had to work on or adjust a carburetor or points ignition system since the early 90s . And I don't miss it , not one little tiny bit .
The first start sounds so rich.
Jet seems clogged in one of the webbers cause the splatter but also seems rich in the other webber. The beauty of carbs
You need to add the grill back into the front
Pro wiring tip:
A seam ripper (a tool used by a seamstress to tear apart clothes) is excellent for cutting wiring harness loom. The design makes it very, very hard to damage the wire underneath. Just find the seam and rip away. Like a letter opener for electrical tape.
"support local". Good remark.
This 3 part series turned me away from swapping my miata, and instead about to order a quad carb setup for it. Always enjoyed the simplicity and driver experience of the car, and feel like this would pair perfectly with that.
I really hope you mean Individual Throttle Bodies.
@@dohc_vtec_dj no, I don’t.
Central Florida reman is who my grandpas been using since I was a baby and now I’ve been using them for last 8-9 years . 60 bucks for alternator or starter rebuilds usually, way better then spending 300 bucks for a reman Chinese pos 😂
This would be a cool build for Taylor to do as a showy kinda driver build....tucked clean bay, nice paint/wrap, clean interior.....just a good running car for spirited drives and cars n coffee....just to enjoy.
Rip to Ken Block. You were amazing 🕊️
Messed with webers alot in my teens, there is alot to getting 100% out of them and some of it is counter intuitive when you are presented with symptoms that are not necessarily caused by your first thought. On the plus side though there is alot of good books written on the subject but the real knowledge gold is if you can get some one to run you through it hands on, it will save you so much time in the trouble shoot phase and flatten the learning curve very quickly .
Dang Taylor with the doors open?? Must be another beautiful day in florida
The first startup that thing sound good and smooth, looked too easy😭
Did you ever check the shim to cam clearance when you swapped the springs and cams and change the shims to give the clearance needed?
Definitely one of my favourite interiors
14:40 is why I'm a toyota fan for life lol
Use a Seam ripper for taking apart harnesses! Lifesaver
Get a seam ripper for the wiring harness tape. Works wonders
Loving the old school content
You should look at 123 distributors as they allow different throttle curves and advances on these old school builds - I run one on my fast road mgb and love it
Don’t think they do one for the 4ag as there’s no advance mech at all. Need to swap to a 4K dizzy, or get an msd programmable
don't know if someone already mentioned it, but in Sweden it's quite common to have a carbs and then you can fit a malpassi filter king which then lowers the fuel pressure and can be used with the original fuel system.
I raced twin sidedrafts for 10 years. I found 4-6 lbs worked the best for me.
Good to know! So future me. Ended up putting the bike carbs back on for diag and it fixed the issue. So something with the carbs was causing it to fall on its face. I’m not sure what.
Another good secret is if you can’t find jets small enough you can Use flux and solder to fill old jets and jet reams to make your own jets if they’re not available.
Stumbles is normally rich. If you let off the peddle and it accelerates it’s lean. Sounds like your 4 secondary jets may be to big.
Best car in the fleet. Love it.
@taylor ray
Your going to want to make sure those carbs are synched together first with an air meter, then you can adjust your idle air mixtures. All carbs should be within a needle width away from each other when checking with a gauge and the needle should be steady! Also fuel pressure you will want at 4psi, I’d also verify that fuel is sprayed at the butterflies while depressing throttle, this can be checked with engine off. Verify that your float levels are correct as well as float drop as that can dramatically change how those carbs operate! I tune Weber carbs all the time and actually just tuned an Aston Martin db4gt with pretty much those same carbs so feel free to ask any questions! I can get float height specs if you need.
It really sounds like a ignition issue when you are driving but I could be wrong. Did you check what jets are in the carbs to se if they are close to what you are supposed to have for your setup.
Ya Taylor ray saved the day with a video!!
It's terrifying to me that these AE86's are almost 40yrs old, I bought a 86 twin cam Corolla hatch new when I was at university, it was a great little fwd hot hatch, swapped it out for a 89 Honda CRX early in 1990, damn I feel old, could have bought one in 99 for about $2 grand, bugger, Rj in Oz
Great content thanks for sharing. Looking forward to 2023 content
Get a 4k distributor it runs off vacuum advance. And smoke could ve the rings. Big 4a guy.
Taylor I don’t know you know but you can get a straight through fitting for the top of the carb so the back carb fuel line goes straight into the top of the front carb and then out and down to the tank, so you then don’t need a line from each carb down into a t piece !
I have set up a lot of weber at work. However I have never set up down drafts so maybe this won't apply.
Weber are super touchy with fuel pressure. They usually want right around 3.5. To much and they run fat or flood out if it is to extreme. Also they are very particular about float height. I would set it off of factory settings.
If you haven't already you need to play with the air screws to check you idel jets. In should make it richer and die. out should make it lean and bring the idle up. Your mixture screws should be happy a turn and a half out. Do not make up for bad idle jetting settings by turning up the idle. For your other jets I would plan on doing some plug checks and paying attention to how it feels. Usually you can tell pretty quick if it is lean or fat.
It’s so funny seeing gts wiring and it’s mysteries 🤣 I’ve owned 9 ae86s myself over the years when they were cheap. That black one kinda looked like o2 sensor connector but I can’t be sure, over a decade since I worked on an ae86
I actually did v8 carb swap into Miata few years back and I just used the fuel pressure regulator and brought the psi down the 5psi for the carb setup and then returned the rest worked good
hey make sure those valve stem seals are properly seated ...speaking from experience, I had a similar issue after replacing mine where it was still smoking, turned out it took quite a bit more force than I thought it would to get them seated properly. I was initally using a Toyotool, in the end I think I used a 3/8 deep socket ...that was 15 years ago and still good today :)
For the carbs they sell a banjo elbow and tee that connect one carb to the other and you only nees one fuel line to feed both carbs. It will make them look nicers and the feed can be passed by the fire wall and for the problem of car has no power you need to set the timing at full advance of the stock ignition at full thottle around 35 dergees of timing
Hey Taylor, I've used a thread cutter from a sewing kit to cut open harnesses before with pretty good results without risk of cutting wires.
My experience with carbs:
1. Check the engine compression
2. Valve lash adjustment
3. Distributor adjustment
4. Timing
5. Carbs 'reset' or 'starting point' manufacturer's spec of jets and idle. Don't raise the idle, it must reach idle by setting the jets/mixture, that's how you know you are on the right path. Then comes 'road tuning' allot of drive-stop-adjust-repeat (small steps, no more that 1/4 of turn)
Tuning/fine tuning of mixture only when engine is up to working temperature.
Then it gets tricky for tuned engines like itb's and header and cams, for making the most of it, allot of research needs to be done on how did experienced dudes set their valve lash, distributor and spec of the jet size.
Vacuum tool makes life easier when having itb's.
If any of above is slightly out of spec, you will chase your tale.
When cold start, idle, driving and power is reached, could be issues with hot start, but should start right up with full throttle, that's because of increased flow compared to the factory intake and exhaust.
And patience:)
I’ve always been amazed with Taylor’s knowledge. Just bought a Miata myself and I’m so clueless but watching these videos makes me believe that one day I might have some knowledge. Keep up the great work man
Sidedrafts on a four cylinder is one of the coolest sounds ever.
A seem ripper will unsheath that wiring harness with out damaging the wires. Cheap tool to prevent damaging your harness.
+1 for the purity on this build. Very refreshing from the restomods. They are and cool and all but nothing like the experience of a car the way it's meant to be.
as a fellow corolla lover this is my fav build you have done. hope you will enjoy drivin these chassis as much as i do.
I tried supporting my local alternator shop last year for my truck. They said we really only do big trucks and tractor stuff and we’d have to charge you hundreds to do a GM truck alternator so it would be cheaper to buy new 😂. So i bought new Oem from rock auto for like 150
Sounds like its not running right for sure. Sound like one of clynder doesnt run, maybe the timing is off or something with the ignition is wrong. Amazing build for sure, love the carbs!
Think that whack routing is to separate the signal and power wires to avoid signal interference
Just an FYI, Mallory (Holley) has a return-style fuel pressure regulator that will take EFI fuel pressure down to 3 psi for the Webers. I've used it with a Weber downdraft and it works mint.
Do yourself a favor and get a set of gauges to balance the carbs and hide a standalone wideband somewhere (itll help with tuning).
I love the iconic 4age motor but another perfect engine that I would swap into the hachi-roku would be Toyota's 2ARFE
Thing sounds amazing wow
Advance Timing or distributer points would be my bet! I'm a old school 4 cylinder guy and I'd be looking at those to things! Sounds mint by the way
There is no advance at all, which is a problem. The 4ag dizzy isn’t a traditional dizzy
@@jamesford3549 oh there you go...mostly worked on Ford escorts and Isuzu/Holden Geminis here in Australia. Had the same symptoms and points in distributer
Love this build. Makes me miss my AE86. Also you know you can manually open your headlight with that little red knob on the side of the headlight housing
Love watching these types of videos.
Nice start. You have to make sure the carburetors are synchronized. If not, the engine will not run properly! Regards Nico.
Beautiful. Miss my 86.
Build coming out clean
What a cool build! I love the simplicity in builds like this.
Couldn't care less about this build, it sounds like a dieing lawnmower. That being said I'll watch anyway to support the channel. Got to support Taylor. Works his ass off and is a great guy.
Such a rad build, this is exactly what I'd do with an ae86.
It's so cool watching two of my favorite UA-camrs build cars with the same chassis, but both have completely different builds.
I watched all these downloaded and came back to give them a like. Keep up the great content man
You'll see us for the next for sure ! Already can't wait.
Love that you were able to get the Weber’s on there like you originally wanted!
I love everything about this car. More fun driving a slow car fast.
This might be your coolest build yet, I really hope you do come back to it and do a full tear down and rebuild restoration with paint and everything (I know aesthetics are not your priority)!!
Oh the memories and the feels coming back from this build. Reminds me of me n my pops in the garage building the show car (55' Chevy Bel Aire 2dr hardtop) and my first few. He nearly had a stroke when I took him to look at a 280z and an RX-7 but I'll never forget he said "shit son it still burns gas, needs the same 3 things air fuel and spark so if you want that 280 get it but that rotary is ALL YOU" 😂
Yea Its got a ignition issue deff need different spark plugs and check that msd box and coil wiring and it was chooochen some smoke
That sounds so good, Love it!!!
