Working on single port 1600 with Solex 34 pict-1. It dies at a stop. I have replaced the electric solenoid on the side and checked for vacuum leaks. I can turn the idle screw in, in, in with no effect. Then all of a sudden I will turn the idle screw and the idle will increase but the idle is to high. When accelerating it misses. Cruising it runs fine.This is my first experience with this SEEMINGLY simple little machine. Any help or advice is appreciated. Thanks-Ed

Hi Ed, had similar behavior from my 73 super. Just bought it and it sat for a while, the carb was very dirty. Removed the carb and completely cleaned it, But before doing so, remove the air cleaner, use something flat like a piece of metal or something that can cover the carb air entrance. Rev the engine to about 3000 r.p.m. and block the carb with your piece, engine will die in black smoke, it's Ok, you'e choking it...remove it before the engine stall, do it again a few time, the vacuum it will create inside the carb might get a piece of dirt thru and unblock some conduits. If this does not fix it, then do like I just did. Remove carb and clean. Make sure the little ports inside the venturi by the throttle butterfly are clean. they are part of the idling circuit. remove the solenoid when doing this and blow air everywhere in all the little holes and conduits. Took me just about an hour to do this , what a difference. it run soooo smooth!
while you're at it, you might want to install a new carb kit. and check that the acceleretor pump diaphragm is good and not punctured or split and don't forget to install the little spring...or it won't pump any fuel in the carb when you'll move the throttle. Try this! it worked for me!

Dear Alain, thank you for your response. As it turns out there are two screws on the side of the carb that are "set at the factory" and are not to be boogered with. Both of these screws were way out of adjustment. I set both screws to factory settings, which is: 1st seat the screw (do not use force) Then 2.75 turns out. When I say turns, I mean 360 degrees counter clockwise. Thats it. Set the points at .017, the timing at 10 degrees BTDC and the car runs like a top. Starts and idles with the touch of the key, smooth acceleration with no miss or hesitation. Very happy with the car now. I hope this helps some one else. Thank you for your input sir. And I too am putting this car together for a very loved little girl. Life is good.

I had similar problems with my electric shutoff so I cut the end off and screwed the piece back in. Every now and the I might have an idle problem just unscrew the jets on the side and blow them out, stick them back in. Also I had a fire in my Super Beetle so I moved the fuel filter under the gas tank and installed a metal fuel line around the left side of the engine.
