David,

I have the exact same setup on my car (all original) – 30PICT/2 Carby and

single vacuum distributor.

Here’s the deal on the 30PICT/2 – a bit long but it’s all there:

SOLEX 30 PICT/2 CARBURETOR ADJUSTMENT PROCEDURE

This procedure should also work for the 30PICT/1 and 28 series carburetors

with a single adjustment screw on the side of the carburetor.

Before we start adjusting this carburetor, the valves, points and timing

should be set. This is important and should be set in order

shown when we start with a cold engine and end with a warm engine. Set those

Valves first – engine cold – at 0.004 in. (this is the factory setting for

Pre 71 engines. Some people find this too tight and use .006). 71 and

Up motors use .006 inches. The aim of the ram adjustment is the provision

practically no gap when the engine is warm.

Now set the points to 0.016 inch. If they have holes or are damaged or if the

Friction pad is badly worn, replace it. Apply a small dab of grease

Cam while you’re at it. Also pull the gyro arm off and have a look

it sits on the spindle. If there’s a felt pad in there (some have it,

some don’t), put a few drops of oil (engine oil is fine) on the pad to help

Lubricate the distributor. Don’t overdo it – just a few drops.

Then set the time. This is typically 10BTDC for 1200s, 7.5BTDC for

1300/1500/1600s with individual vacuum manifolds, 5ATDC (that’s AFTER) for

Dual vacuum manifold and between 5-8BTDC when using a 009 centrifuge

distributor. If you have an 009, set the max feed to 28-30 degrees with

the engine is running at more than 3000 rpm, and then check the idle adjustment.

The 009s vary a bit in overall feed, and the maximum feed is larger

more important than idle feed, so you need to adjust it as described.

Now warm up the engine, remove the air filter from the top of the carburetor (if any

the oil filled kind, be careful you don’t need a shoe full of oil) and

Check that the throttle valve is vertical. If it doesn’t, run the

Run the engine a little longer to ensure it is fully warm and check the choke

butterfly again. If it is not vertical, the butterfly needs

Adjust or Fix (different topic).

It is important to set the valves, set valve timing and check the choke beforehand

Adjusting the carburetor, they all work together to keep the engine running smoothly.

ADJUST CARBURETOR

On the left side (left is the left side of the car) there is a lever with a cable

associated with it. This is the THROTTLE LEVER. On the throttle is a

small screw sticking out to the back of the car. This is IDLE

ADJUSTING SCREW. The idle adjustment screw rests on an odd looking surface

Piece of metal with incised steps. This is the FAST IDLE CAM and it works

with the choke to ensure reliable idling when the engine is cold. The engine must be

warm to adjust the carburetor so the choke is off and the IDLE ADJUSTMENT

SCREW sits on the bottom of these steps.

Just below the fast idle cam on the left side of the carburetor

see a screw with a spring wrapped around it. This is the VOLUME CONTROL

SCREWS. There is a barrel shaped object on the side of the carburetor body, something like

the size of a pen light battery, with a wire connected to the outer end.

This is the IDLE FUEL SHUT-OFF VALVE (solenoid). This includes the fuel if

They turn off the engine to prevent it from “running on”. Be sure the wire is

connected and runs to the (+) terminal of the coil. (This usually expires

same wire that connects to the choke.) Also make sure that this magnet

is screwed firmly into the carburetor and does not rattle. Don’t overtighten

but it has a fine brass thread and screws into aluminum – both

fairly soft metals. You can test the function of this magnet very easily.

Switch on the ignition and disconnect the cable from the valve. Touch the wire

plug and you should hear a clicking sound when the valve is in

emotional. If not, check for 12 volts on the wire (small malfunction light,

voltmeter, etc.) and if necessary replace the solenoid – if it does not work,

They won’t get a proper idle and will idle erratically at traffic speeds

to.

As mentioned, make sure your engine is warm and the choke butterfly is on

stand upright. Make sure the air filter is on when you adjust it

Carburettor – the engine expects it to be there.

1) Turn the VOLUME CONTROL SCREW all the way in – CAREFULLY PLEASE. It is a

needle valve, and you don’t want to enlarge the hole by forcing it home. now

Unscrew 2.5 turns. This is the starting point for customization.

2) Start engine and turn IDLE ADJUSTING SCREW in or out to adjust

Idling at 850 rpm. I’ll let you figure out how to measure 850 rpm – but it’s a

fast idle.

3) Then slowly turn the VOLUME CONTROL SCREW in until the motor starts to spin

let it drop off, then turn it out until the engine runs at maximum idle speed.

It should still be within 1/2 turn of the starting setting of 2.5 turns.

If the hole was damaged by a previous careless person, you just have to do it

to do the best you can. Now screw it in until the speed “only” begins to drop

– about 30 rpm. This is the final setting.

4) Adjust idle speed again with IDLE ADJUSTING SCREW. Don’t slow down

Idle too much, 800-850 is about right. VWs need a few idle revs to stop

the cooling air flows, otherwise when coasting at traffic lights

after driving at good speed, your hot engine does not get enough cooling air,

and it won’t like you very much.

That’s it – you’re done. It should now be purring like a kitten.

it is very difficult to remove.

I discovered that earlier picture 2 also has another hidden screw. Located at the top of the carburetor, it is an adjustable idle jet bleed screw. Very beautiful!

I am using this older post to show the photo of the famous hidden “screw” of a pic 2, it is very difficult to remove. I discovered that earlier picture 2 also has another hidden screw. Located at the top of the carburetor, it is an adjustable idle jet bleed screw. Very beautiful!

I thought it was the Solex 30Pict 2 but I read somewhere that this was not used until 1968? That makes the Solex 30Pict 1 the stock carburetor for the 67 bug? Thanks very much!

Posted: Wed Jan 19, 2011 06:37 PM Post subject: The 30PICT-1 was the carburetor used in 1967. The one used for 12v US Spec 1500 bugs had a base flange modification state number of VW 105-1 and the matching distributor was the 113905205K.

The 30PICT-2 nozzles are of course all removable. But behind this small screw is not a nozzle, but a needle.

Posted: Sun Jan 23rd 2011 6:38pm Post subject: Solex 30 PICT 2 What is it?

Please ignore the dirt, filth, leaves and pine needles, I’ve only had it a week.

What is the snout-looking object? How do I set it up to make it work properly? Is it worth sticking with carbs? Any suggestions?

The photo shows the carburetor on a new (to me) 1968 Std Type 1. I’m wondering what that snout-like object is that’s attached to the front of the carburetor linkage by a rod that pushes and controls the idle on my Beetle. When starting, the engine idles great, maybe a bit too slow, but it idles. But after warming up, the engine idles at high speed. The rod/piston coming out of the snout object controls the idle by adjusting an arm in the linkage. Please ignore the dirt, leaves and pine needles, I’ve only had it a week. What is the snout object? How do I set it up to make it work properly? Is it worth sticking with carbs? Any suggestions?

Posted: Mon 24 Jan 2011 8:52 AM Post subject: This is the throttle actuator. It’s only intended to hook onto a secondary lever that opens the throttle when you’re “engine braking” – preventing the carb from closing completely even if your foot is taken off the pedal and continues rolling in gear – this leaves enough Air in the mixture to reduce the amount of unburned hydrocarbons exiting the tailpipe. The 66-69 Bentley manual has a few pages that talk about it.

Very original looking decor there! Even if dirty… still unusual to see so many original parts together.
