Has anyone rebuilt their own carby before?

I have had some carby building pro's tell me that my triple Dellortos are full of crap, and they have quoted upwards of $1,600 to rebuild and tune them. They've warned me that if I have a go at doing it myself (at about a tenth of the cost) I'll get it all wrong and will come crawling back to them anyway (and with no experience to my name they may well be right.)

I can buy complete, new triple webers on a Datsun manifold for around $1700, but they wont be jetted to suit my car, so there will still be some additional expenses tuning them.

At this stage I am tempted to buy a book and some gasket kits and have a go myself. Any suggestions?

I can point you to the man who kept my webers on my datto and many others carbs running perfect-

Hi.

The dellorto and weber are a fixed jet carby so relatively easy to maintain. If they are dirty and you are not sure of doing the job remember they are two identical barrels so take out the jets on one side and you still have the other side for reference. These carbys are not hard to work on.. One point to think about the Dellorto is no longer made . .

If you are not confident take them to the man mentioned above.

I know and trust Randy, but he is way over on the other side of town... Still for the final tuning and jetting he probably is worth the drive.

Thanks for the heads up about doing 1 side at a time. Although the Dellorto carby bodies are no longer made, there is still a bunch of Dellorto parts being bandied around ebay... I'm getting more excited about pulling them apart myself.

If you are still going to Hanging Rock tomorrow, come and find me (at NDSOC group), we can discuss.

Basically, I wouldn't expect the cleaning part to be that hard, tuning is the bugger bit.

Never worked on a carby before; but if you feel like having a go I'd spend the $160 and do it. Worste case is you muck it up and have to go 'crawling back' and it costs you $1760 - best case is it costs you $160 and you feel like a champ!

Birth... that is such a cracking point. So far I haven't found any posts saying "leave the rebuild to the pros," and like you said, if I do botch it, being $160 out isn't exactly a disaster. What's more, if I get it right, it'll free up a bigger budget for jetting/tuning (a job I am more than happy to leave to a pro) and other miscellaneous parts and repairs.

Further, most 'pros' don't care about you or their car - they are like anyone else who is at work thinking about going home and doing other things. I generally ask myself if their training / experience will offset their lathargy. In most cases I would prefer to muck stuff up for free rather than pay someone else to muck it up for me!

Funny you should say. The last carby specialist (he did nothing but carbys) I went to talked me into a big dollar rebuild of my SUs, and when the car didn't run right told me it had to be an ignition issue. I took the car to Nissco to have a look and the thing was running so rich the O2 sensor went right off the scale.

I had to go back and ask the carby guy (despite wanting to tell him go to hell) to sort out his first attempt, but not before I had dropped $400 into a completely unnecessary ignition upgrade!

    • @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man
    • Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?
    • Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
    • Assuming your brake pads are not worn right down, I'd add a little brake fluid. Is there any sign of a brake fluid leak?
    • Hello all,  I need of some help. On my drive home my handbrake light lit up and started flashing. When I got home I checked my handbrake sensor under the centre console and nothing seemed out of the ordinary. I have scanned my car via the consult port, no codes shown. Checked my brake fluid as well which is half full. Tried unplugging the brake master but it didn't change anything. Thoughts on what it could be? The master float doesn't seem to be stuck. My car is an 1998 ER34 sedan GT. No hicas but has ABS Photos below 👇🏾
