74' Beetle stalling HELP!
Burgo - October 20th, 2009 at 05:34 PM

Hey hey all,
Ive noticed that my 74' L- Bug has been (particularly in the mornings) been stalling when Im slowing down in the low gears.

For example I'm just pulling up to the lights and once it gets to 1st gear it will just sputter dead..SO I'm frantically putting on the handbrake and re-starting the motor again to get the stupid thing going. Other times I will be idle and the thing will cut out as well.

This doesnt happen 100% of the time but it just gets into these fits of doing it. Ive made sure I'm not doing anything stupid like releasing the clutch or not giving it enough revs.

Another thing is I want to be sure my fuel gauge is really accurate because I have noticed it moves around abit, so is there any way to tune it?

Any advice would be much appreciated.
Thanks,
Burgo

I would just start with a good tune up so you have a solid base to start with

More than likely it is sonething minor like your points have closed a tad so your timinging is slightly retarded which will drop your idle a tad which will

You get the point :yes:

start with the easy things that cause that kinda behaviour

check the idle jets not blocked

make sure the cutoff solenoid is working when u turn the ignition on

and spray some wd40 or carb cleaner around the manifold boots and carb base to check for air leaks

dude what are you doing putting the handbrake on? totally unnecessary :smilegrin: just giving you hard time man:D

do you think its still running rich dude? i would definitely check the idle jets like joel says

Ok, got it checked out by a VW mechanic in Mitchelton, and turns out my carb has had it and its affecting the idle jet etc.. So i gotta get a new carby. *sighs*
Got the jet cleaned out so its running a bit smoother now :)

And izac, I put the handbrake on when im on an incline, so i dont roll back when i have my foot on the accelerator and not the brake whilst im starting the beast with my starter button. That way i dont roll back into the frustrated line of traffic behind me :(

Thanks for the advice all, much appreciated.

Consider getting your 34Pict rebuilt / rebushed

Cost the same as new inferior stuff and you have OG quality stuff

Carburettor Service Company in Sydney does it
I am sure some one in Brisbane will as well

To be honest I've yet to own an old VW that doesn't stall in the first few minutes!!
To prevent stalling you need to learn the art of pressing the brake pedal with the ball of your foot and then be able to blip the accelerator with your heel :)
That's what i do anyway! :)

On my 34pict I added an O-ring and washer to both sides of the throttle shaft against the carb body which reduced the air-in leakage by about 80% and enabled it to at least not stall, a quick fix but not as good as a rebush, bit cheaper though!

i thought that you had to learn HEEL TOE to drive a VW on those cold morning

My 73 is stalling. Mechanic reckons it is the idle jets being blocked.

Is there any tutorials on doing this myself, don't trust her driving another hour to get her to the mechanic :(

I agree with what the others have said, the shaft is probably worn... i prefer the idea of a propperly rebuilt and bushed version. Then you know you have a servicale carb. Realisticaly though you could do a dodge and stop the leak if you were hard up for cash... but if you spend the money now, you will have reliable happy motoring for a while to come.

PS if you are spending the money on a new carb why dont you spend a little more and really make it sweet.
Distributor cap, points, spark plug leads, condensor, rotor cap, inlet manifold boots, fuel filter, fuel hose. And adjust rockers, and timing

Then you have eleminated many of the possible prolems with not too much cost.
