Posted: Sun Feb 12, 2012 7:44 AM Post subject: Brosol Solex H30/31 Carb Jets? Can anyone point me to a supplier(s) that sells carburetor jets for the Brosul/Solex H30/31 carburetor? I put a new one in my ’71 bus and the main engine is a 120 and it’s too lean. I prefer not to open the existing nozzle but try a few replacements. A jet kit would be nice. I think probably a 127.5 or 130 would be a good place to start. Many Thanks.

Found that in the link.

The H30/31 carburettor has two brass jets on the right side (right is on the right of the car). The angled one (points slightly backwards) is the idle jet. The other (pointing directly to the right side of the car) is the Power Jet, which supplies extra fuel at high throttle/high rpm. The power jet is needed to correct the tendency for the air correction jet to work TOO well at maximum airflow – it leans the mixture too much and the power jet corrects this.

This information is incorrect. The idle jet is towards the front of the vehicle, the power jet towards the rear of the vehicle. Rob and Dave’s page is bogus and has been the source of quite a few threads about which jet is which.

Edited for jet names

Posted: Wed Aug 12, 2015 5:47pm Post subject: Ok, what am I missing here. The positions appear to be correct. Is it the nomenclature that confuses the issue?

Glutamodo says so

No. 3 is the idle jet (pilot jet)

#0 is the aux jet (power jet)

#3 (angled (pointing slightly toward the rear of the car) is the idle jet.

#0 (pointing directly to the right side of the car) is the Power Jet

glutamodo wrote: With the H30/31, the additional jet is 50, the idle jet is 65.

The Power Fuel Jets are located in the top half of the carburetor.

Thanks

Pos. 9 air correction nozzle

The table lists the following:

Air correction nozzle 60Z

Main jet x125

Pilot jet g57.5

Compared to the image in question, the nozzle sizes are all slightly larger, but it makes it clear what nozzle each size can reasonably represent.

I wish the Bentley had been more specific, but of course we all know how vague it can be on some subjects.

But Andy’s diagram shows the similar jet layout as the 30PICT-3 bus carburetor. But what confuses me is if an idle shutoff is used, why is it screwed into the one marked “auxiliary fuel” when it would be more useful in the idle circuit. If it only comes into play at full throttle, why does it need a shutdown, and why should the supposed “idle” not need a shutdown?

I need to find some junk carb and cut it up to see where these passages go.

So

Busdaddy, what carb is the picture of? The pilot jets on all my 30pict3s are like your picture. The power nozzle is not adjustable. [Colin looked it over years ago and ended up drilling out the passage (or nozzles?) for experimentation.] The solenoid shown is for the idle circuit as well. This is where the H30/31 differs in that the power fuel flow is said to be adjustable. The H30/31 has the cutoff on the left like a 34pict3. Now I’m confused because of all the charts and labels.

Learn how your vintage VW works. And why not. After playing around with an H30/31 for a year, I went on to play around with a 34pict3 for two years. Now I’m on the 30pict3 bandwagon, and I think I’ll stick with it for a while. That being said, they are all completely different in terms of installation. It’s not obvious when looking at the plumbing, but following the passages with liquid and performing flagrant LM-1 based jet swaps (like 45 to 70 pilots) tells us a lot about how they are all so different . The charts are useful for numbers and locations, but we must be careful not to remove labels from other carb photos. For example, Glutamodo posted a picture of the 31pict3 and then described it as H30/31, even though some variants of these carbs are different.

I nicked it from the gallery, Dana Champion posted it and says it’s 30PICT-1 and -3. The carburetor in the picture says 30PICT-3 on the side.

Does anyone here have any MFR literature on the carburetor with a breakdown?

Glutamodo, who knows more about carbs than probably anyone else here, says the H30/31 copies its idle circuitry from the non-US 31pict3. The image below shows the 31pict3 which should be identical to the H30/31. This means that the slanted rear jet is the idle/ignition jet and the (0) jet is the “power” auxiliary fuel jet. (As far as I know, 30pict3 and 34pict3 don’t have this jet as a serviceable item.)

The photo is from VW Technical Bulletin K-40, April 1971, and Glutamodo did the translations himself.

I don’t have any books on the carbohydrates that Glutamodo refers to, but I wish I had. It would be very helpful to be able to compare the numbers with the 34 pictures of 3._________________Robert in Memphis
