Hello, all! I am a proud owner of a 1971 Type 2 Volkswagen bus. Sadly, it has started to develop some problems. I can usually get it to start, but the idle is very choppy. When I start to accelerate, it doesn't seem like it wants to go and will "surge" and "chug." It will not function above second gear. My father suggested that it was a loose connection with the distributor, but after fixing that the problem continued. I'm really new to self-repairs (My father usually took care of all the maintenance in the past, but I've since moved from home and need to "learn the ropes," so to speak), so please be as specific as you can. Any and all help is so greatly appreciated. I'm thinking it could be a vacuum hose? Thank you all in advance!
