Helping my friend with her bug again:
Basically, the problem is that it does not want to idle. I'm pretty sure it's a simple problem related to the throttle, "strangler valve," or one of those levers. I've been working on adjusting the little screws and stuff (fig. 1,2, & 3) with mixed results.
I had it idling for a while at a high rev and then tried adjusting screws 1 and 2 and it stopped idling, then I couldn't get it back. That's when I decided to hit up the forum for advice.
See the thing circled in green? Looks like its threaded and something is supposed to go in there. Maybe not. Huh.
Anyway I'm not very experienced with Beetles, any help is much appreciated. Danke.
