It's a long while since I worked on a VW engine. As it's a 76 model, does it have the type 4 "suitcase" engine or the Beetle type with the upright fan housing?
I remember my 73 2.0 type4 engined Devon camper was a really thirsty beast
I also remember a looong drive from Newquay to Leicester with a broken accelerator cable and having to hit the starter with a hammer every time we stopped because the solenoid was sticking on my 64 split screen canterbury pitt camper
Lots of videos on youtube but I can't post the links
