O.K so I just got my new weber 34`s for my 1.7. I installed them and started the car. Prior to this I installed a new fuel filter and fuel line. The other line was cracking and sort of scary. So my question is related to vacum. It looks like the intakes were made for an advance. They have a port on them so do I just plug it. Also at the bottom of the carb itself there is also some sort of port.My last question is some parts that were missing when I got the car. On the oil fill cap port there is a small elbow coming off of it. It looks like a PCV valve would go there or something but I have nothing. And on the engine block there is another port. Look at the pics and hopefully some one can help. I think the car is close to running but I want to make sure what these are for. Thanks Joe.

Ok, so here are the answers;
1. The port on the "case" is really on the fan duct and it was used for emissions, to blow air through the tank vapor recovery system (Evaporative controls). Cap it and forget about it (or tap it into the air cleaner for a supercharger effect, (IMG:style_emoticons/default/laugh.gif) ) 2. No advance so plug the carb vacuum ports. Good luck! I had the set of 34 Dellortos on my first 914 and they always ran rich so I hope the webers work better. |

I have never tuned carbs so I should be in for a treat.I need to do some reading so I better get started. |
