My condolences on the passing of your father. Mine passed many years ago. There are still questions he could have answered and I am 77.
Oh no... that lad was way to young to have passed on. My condolences to you and your family for your loss.
Amazing Webbers. Like a work of mechanical art.
Greg Bird thanks Greg
Kavs in 2015 my family endured the sudden death of our father and we sulfured terribly emotionally and psychologically over our lost,just like yourself we had previous loses that had happened in a very short time of other love ones.I was going to thank you you for sharing in such generous detail the reconstruction of the engine only to arrive at the end of the video to see that your wonderful nephew had died just after your father.All the best to you with the hope that you will quickly recover from your grief.
Sorry for your loss, love the flat 6 bad ass engine.
Sorry to hear about your loss, may they rest in peace. It is inspiring to see your strength and dedication through your hardship.
Thanks.
You sir have made me fall in love with the air cooled Porsche flat 6. It's such a marvel of engineering, and I hope to be able to work on and own one some day. Hats off to you skills and knowledge!
Am enjoying your engine strip down videos. Looking forward to the next episode! :) Putting the Carburetor back together!
Coming soon!
I'm enjoying your channel. Back in the mid-70's I owned a '72' 911T with mechanical fuel injection. Loved the car, but lost it in a divorce. Looking forward to seeing more of your videos as I enjoy doing R&R work....mostly RWD Volvos and BMW motorcycles.
Thank you for your informative and well presented series, I have an old 993 which I have been neglecting............so I'll be back on the spanners soon I suspect. Sorry about your Dad, it will be a tough Christmas and new year without him..........all the very best with your project for 2020
What a gentle way to follow a master up on his learning curve. Many thanks! Stay happy and healthy!
What a fantastic job you have done. It has been an absolute joy, to watch it. That engine is a sculpture. I could have it standing in my livingroom, and never get tired of looking at it. Thank you for the video. My condolances. That kid was just too yong to go. R.I.P. 🇩🇰🙋🏻♂️
Thank you Hector.
very sorry about you dad iam sure he was a great guy and loved you
Very nice video! I did a video on rebuilding zenith carbs of a 356 a bit back and got several requests for Webbers. Now I know where to send folks! Great job. So sorry for your family's loss. Franny
Thanks Franny. Glad you're enjoying the vidoes. Love your content too!
I found the thread a few days ago, and am caught up on the progress. Can't wait to see another video. I want to see it broken in and eventually running. Thanks for the work. Sorry for your losses.
Thanks Warren.
Nice detail on the functional parts of a weber.
Thanks Tom.
Subbed. I've learned a lot watching this series. Not least of all why Porsches are so expensive to maintain. lol
Tell me about it! Thanks Daniel!
In one of your vids you expressed doubt about continuing to use POR 15 throughout the restoration because it's a pain in the ass. I would use that stuff no matter how big of a pain in the ass it is. It will preserve your car.
I'm ready to hear your rebuild fired up. Subbed.
Me three!
Nice video
If I was rebuilding them, I would never be able to put them back together....!
smaller venteries mean higher velocity,which is good for low end throttle response,I used tomess with dual webers on alfa,s and fiat spyders
When you smash the like button before you even start the video.
Hahaha! Thank you Roger! It's all about the likes apparently!
A carb is a delicate thing. If it´s not perfect, the engine will never run quite right. The thing is, you usually don´t notice that until you have the comparison in engine performance between a perfect carb and a not quite perfect carb.
I'm starting to get scared of your videos, 2 videos watched, 2 in memorian. Anyway, I hope you are ok. Great content.
We've had a terrible year as a family unfortunately.
@@kavs911 Man, I am so sorry. I wish you the best.
I hope you are ok, best wishes for you and your family.
Thank you for the kind wishes.
Hello, great work, I use a ultrasonic cleaner to clean carburetors, 6ltr model off ebay fits a lot parts. Cheers
I will look that up! Thanks!
👌Very Wery goog !
Good wark
SO, FAR YOUR DOING A GOOD JOB. I WOULD LEAVE THE TOP, PLATES THE BUSHINGS SEEM GOOD...
I'm one of those guys who would have polished every screw, cap and tube that was brass to a mirror finish. I know it wouldn't last very long it's just me, lol.
Great rebuild series! have just binged watched all upto date - this isn't helping my insomnia!
Ian Bach Hahaha!!! Thanks Ian!
I did the same. I couldn't stop watching them.
Hey Kav, sorry if someone asked you this already. I found a post you had made on PelicanParts and saw that you had been dealing with wiring on your car at some point. I see that the 1969 911T is specific to that year only and a lot of other people are having difficulty tracking down a diagram that isn't the SL33 diagram for the 911S,E. I believe like you, that my car has had someone just randomly place wires over the years. It would be great to track down a schematic. Have you had any luck locating one or can you point me in the right direction? I know Sierra Madre says they have a specific one for the 1969T, but i'm not certain if its just the SL33 or not. Any info you have would be great! Thanks
How in the world do you get the AFM synched up on each cylinder? To do it properly it seems like you will have to have access to a 4 gas analyser and ports on each cylinders exhaust.
You must be smart as HELL....!
Albert Sautner I wish!
Whilst you have them that torn apart, you´d be as well doing your butterfly shaft too, bunch of roller bearings & seals in there that are so old they are not worth not replacing, don´t want any air leaks cocking up your fuelling after such a fine rebuild :)
I hear you but unfortunately that shaft work on these triple barrels is very expensive. I'd rather roll the dice first as they may be fine.
There is no roller bearings on the triple Weber’s. The throttle shaft has a thin nylon bush on the leaver end, but other than that, the shaft runs directly in the bores. I’m sure, from the looks and mileage on these that they are leaking air in around the shafts.
@@kavs911 How´s it expensive if you do the work? Must say I´ve not done an IDA but done plenty DCOE´s and it´s not hard, the nastiest bit is grinding away the splayed screws to remove them from the butterflies. Now, if you find that you have leaks after your full rebuild it´s another full rebuild to clean out all the grinding dust...
@@rodgraff1782 even easier to fix then :) Must go google the IDA´s - it´s been a couple of decades since I played with DCOE´s and I´m getting nostalgic!
My only advice is make sure you have no vacuum leaks in the main shaft. I've had carbs were the bushings wear and create vacuum leaks.
Yes Thank you Cevan I will look out for that.
The shafts themselves actually wear out due to the intake pulsation. The shafts and throttle plates are constantly being pounded back and forth at idle, and this wear things out in short order. It’s not just a matter of replacing the nylon bush. New oversized throttle shafts need to be installed and the bores in the carburetor body are reamed to fit. Then everything is then calibrated on a flow bench to make sure all bores flow evenly. If you have worn bores you will have spitting and coughing at idle up through the air horns due to lean mixture. This will vary with ambient temperature.
When will you do the start up and first drive?
I just stumbled across your channel and I'm really enjoying it. Really great work. I do have one critique though. I may be alone, but I'm not a fan of the music you started adding in the last few videos. I'm already looking forward to your next video.
I hear you, it's for the kids. :)
I found the music A-OK!!
have you thought of doing injection?
they make weber style throttle bodies now even with 2 injectors!! nice for multistage fuel feeds for hungry engines..
use one injector for idle and then fuel more with high speed or boost on the turbo engines.
jus a tip from an old school tuner that uses modern tech these days!!
webers are nice... if you run the car as a daily driver...
if it is for a race day only or nice day type of car... the injection works better..
better fueling..
and gets rid of the issues with stored fuel in the carbs...
Not on this little engine.
what happened to your nephew iam very sorry he seemed really, great what a shame very sorry sir hope things are better for you a better new year for you
Appreciate the content you're sharing. Have another question. On the back side of the carb there are seemingly two ports for the center carb jets. Wondering if these are plugged as I didn't see you remove anything for the extra hole to be there. Also wondering if the left and right bank are mirrored where maybe the left bank has the right side of the center carb plugged and the carb block for the right side has the left side plugged. Seemed weird to have what looked like cast ports that went no where.
Thanks! I'm not sure I follow Daniel. There are three main jets on the back of the each carb and yes they are the same casting just the shafts and top plate are oriented for left and right.
@@kavs911 on the back as you view the three jets there are four holes. 3 have jets and the third was empty. There is also a hole higher up on the backside which looks like it has been plumbed in the forge. Just wondering if those holes do anything and just weren't mentioned or maybe they're plugged and do nothing.
@@danielsimpson8929 Ah right, two float bowels and three jets, the other holes are just blanks and don't do anything
hey is it really that expensive to repair or restore a 911? i mean in money how much do you think in engine parts , some suspension, brake pads and the most common in your experience, just the parts LABOR is free for me... can you give an estimate?
Again i can't imagine the nightmare of adjusting those carburetors. Even when the Webers are the best carburetors for sport cars, they are a little hard to adjust. My dad had a Fiat 131 with a Twin cam and twin Webers, adjusting both was time expensive.
I'll agree with that!
Those air correction needles are not where the air comes in to the carburetor. The air comes through the throttle plates. The air correction adjusters are for fine tuning and balancing the throttle plates at idle. We test this using a manometer, which is the most accurate way. You are going way to big on the chokes. Your going to loose velocity, and your not going to transition well, and have an off idle stumble. You still still have the small T ports in the head, so going beyond 30 serves no purpose. Stick with 30mm. For a 2 literT. The carbs were actually derated for the T, so there would be a bigger horsepower difference from the E. They made a power kit to upgrade the carb performance for the and 30mm chokes were a part of it. I’ve been though all of this with my1969T. Be sure to re curve your distributor for the E cams. Our car is running a 2.7 short stroke engine now, and the proper size chokes, or centuries as you call them are 34 for that setup, due to the larger displacement, and larger ports in the heads.
Yes understood about the air correctors. Yes I am eventually going with 30mm chokes.
What is that for a tool to connect a wrench with the torque wrench?
kavs911: Dude you have left us out of the loop completely here on youtube! According to your Instagram the car has been finished months ago. And not a word here. What were you thinking?
All in good time!
Will you make a clip how to adjust the Weber Carburetor to the running position? I could not get my car started at all. I have been rebuild but after installed to the car it won't start at all.
Yes!
Where did you get your rebuild kit for the carbs.?
Parts Klassik
@@kavs911 I found the rebuild kits and got it running. Sold it to a guy in Europe 😂
hope your prime the oil system before starting the engine, or at least remove the plugs and crank it over with no load until the oil pressure is up to snuff.
Yes will prime the system and build pressure before starting.
@Bryan Ryan Yes will prime the system and build pressure before starting.
@@kavs911 ever heard of accsumps? its container that hold reserve oil under pressure and you can use the device to pressurize the oil system before starting, I have never under stood why the auto engineers wont put a pre oiling system in production cars,most wear occurs during start up, and even more if the engine has been sitting for awhile, really cold climates will turn motor oil into frozen honey
@@tomashton1781 "Most wear occurs during start up" : What don't you understand ? It wears and needs maintenance !! That's what it's all about : keeping the dealerships alive.
Need an update... 😕
Coming soon! :)
Not sure if you’re doing this, but wet blasting seems to be the way to go for cleaning the exterior of carburetors. ruclips.net/video/GyfeFpmbFTw/видео.html
New videos?
Soon!
