Hey guys,
Been a while since I've posted. Anyhow, my stock '67 has been acting up lately and I want your knowledge to help me figure out why.
After getting off the throttle, say on the freeway, the car dies. Today was a nightmare in that the car didn't want to idle at all. For a while, the car would turn off when I was exiting the freeway and then I could fire it right back up- so I thought it was just a carb issue. Today was crazy though.
Limping the car home, I tried to start it just now and it just turns and doesn't turn on. Seems like there is no spark, as I don't hear the usual firing noises. Could it be the coil? Not sure what to check out first. It has been a long while since I've wrenched on my bug.
Thanks!

Are you running points or a points replacement?
Do you have some sort of "box" in the system?

I would first pull a plug wire to see if you are getting fire. If no fire to plugs then go and turn on ignition and take a small screw driver and open and close your points they should have fire if not then I would say you have a bad coil or condensor. Before replacing coil make sure you have power at the coil if power is coming to coil then most likely you have a bad coil

if you have a 009 dist. make sure were the condensor com into the distrb that its not ground out. I had one do that everytime I would hit a bump it would either stall or sputter

x2 When my car did this, it wouldn't even crank back. It'd fire once in a while but wouldn't run. Did the "Finger on coil + side with forearm against decklid" test to see if the box wasn't bad, it checked good. Haha. When I got the coil off the car, you could shake it and it sounded like it was full of liquid, got a new one and it didn't sound like that. Ever since I've had the bottom of the lid propped open by a tennis ball, until I start school and I'll make a new extended latch, in hopes of not frying another coil. |

Are you running one of those late style PICT Solex carbs with the fuel shut off on the side of the carb?

changed the coil. Still won't turn on.
It sounds like it wants to start, it is almost there. but nothing.
It just turns like it wants to, right at the edge of starting, then it goes to just cranking.
maybe fouled plugs?

I would go ahead and upgrade to an electronic setup. It's easy, quick, dosen't cost much, and will eliminate lots of maintenence in the future. A win-win situation in my book  |

put in a brand new compufire. still doesn't start!
I got fuel. Got spark.
I think it is in the carb. As it is, I believe a 30pict, with that damn cold start (brass colored cylinder stuff sticking outta the side of it.
Could it be that? If so, how do I bypass it or not use it? Do I just disconnect it?

It could be the anti-dieseling solenoid. if the coil wire is too close to it then it can interrupt the flow of current through the solenoid and shut it off. It usually happens at low RPM. I asked a friend who happened to be an electrical engineer and he said that a high voltage electrical charge such as in a coil wire could actually shut off the solenoid. I actually had this problem on my old 1600 where the coil wire ran right by the solenoid. I moved the wire and the problem went away. Don't know if this is your problem, but check it anyway.

If you still got problems after all that then try take off your tail light wire and plug it in to your coil hot and turn on your parking lights and then try start and if it does then change your ignition switch.

UPDATE!!!!!!!!!!!!!!!!!
I decided to take off the wires to the carb (why can't they be just carbs free from technology??) and the car started right up!
Now I have ZERO wires running to the carb. It had a hot lead from the coil to the solenoid and from the solenoid to the choke.
So they are both gone and the car runs. HOWEVER, it still will stall out. Do I just need to adjust the carb now? What should I do. I am just glad that I can start it, drive it if necessary and move it when I need to.
Any suggestions?

You need voltage to the solenoid on the carb otherwise it will shut off the flow of gas.

You say Pict 3? If my memory serves me right, that is also a idle jet, take it out and put in a regular idle jet and see what happen, just put in the same size, guessing 55 or 60 idle. If it works, there ya go. Now you won't have any wires to it.

FINAL UPDATE!!!!!!!!!!!!
I feel red in the face. I went to take off the old solenoid and replace it with a spare I have lying around and what did I find...
It was loose the entire time, thus making it too lean to keep the engine on. I tightened the damn thing up and the car fired up and idled like a champ.
OMG. Cars can be so humbling at times. After countless engine builds, racing and the like, there is always something to learn.
Thank you everyone for your dedicated and sincere help with this issue. All is well in VW land.

Had same loose solenoid before when I paid someone to change transmission (need to remove the engine). Though engine was not shutting down but had dark exhaust smoke and fuel consumption increased a lot.
