Stalling Issue

[EZ Gruv]

Hello again.
I present my new-to-me 74 Super Beetle, and yes, it is stalling at lights/stops.

Background:
New points, rotor, cap, wires, fuel filter, even new distributor.
I tested the idle solenoid, it clicked every time.

I know very little about carbs (my bus is FI), but with my Idiot book by my side (Bentley on order), I adjusted the idle screw to see if it would stop the stalling, to no avail.

After multiple stalls, I went to the engine compartment:

I see a gas drip from here:



I start it again and see a drop forming here:

That's pretty weird there Eric.  The areas that you are pointing to is the throttle shaft and the throttle shaft lever.  There's quite a few things to check.  If it is truly leaking from that area, I'm willing to bet that your carb's bore for the throttle shaft is worn out.  You should not have fuel leaking out there.  But what's weird is fuel doesn't usually leak out, air usually leaks in.  Are you sure that the hose is tight to the top of carb?  and the brass barbed fitting (that the hose connects to) is securely in the top?  If they're loose you might have it running down the side of the carb.

I'd take the top off of the carb (5-6 screws) and check the float and the bowl.  If the float has sunk, you'll over flow the bowl and fuel will leak too.   I'd take the carb off and give it a thorough inspection, and possible rebuild.  If the throttle shaft is shot, it's likely the carb will need to be replaced.

Good Luck with it!

Well, I finally got the car home today.
I adjusted the carb using the instructions here http://www.vw-resource.com/34pict3.html
It didnt even try to stall after that.

Now I can delve into the fuel drip!

Congradulations Eric!

I'm glad it was just out of adjustment.  How did it run?  Be very careful with that leak.  All you need is an arc, or the heat from the exhaust to light it up! 

Check the connections around that fuel filter too.

I bet it feels great to have the car home!

Hey there EZ Gruv! I just recently discovered the problem of my carb...just like yours, I had a hard time tracing the source of fuel drips in mine.  As you are pointing in the pics, the fuel drips are coming from under the linkage and accelerator cable. Check if your linkage has lateral play. If it does, then your carb housing already has clearance that the shaft from your linkage to the butterfly already has play.  That's where the fuel is coming from.  I experienced that in the high rpm range (around 3.5 rpm) my engine felt like it's not getting enough fuel. It shudders like crazy. Brought a new carb and my problem is solved! You can also buy a used carb just make sure that it's in great condition. Hope to be of help to you and your v.w.!
