Sounds like your engine is built up as a '72, so you need to do the '72 tuneup proceedures. Note that the '72 tuneup proceedure is unique and ONLY the Bantley manual gives the corrrect instructions for this. You really must have a Bentley manual if you want to own this car. I have one of these for sale right now if you're interested. The fitting that is broken off is your vacuum advance port. That should connect to a port on the upper left of the intake air distributor. There's usually a right angle fitting there for the hose. It's just after the big rubber elbow at about 11 O'clock. It might be possible to fix the broken plastic nipple by soldering in a metal one from an old dead vacuum advance donor. Normally I wouldn't bother with this, but new VAs for this year cost about $100 and are hard to find. I may have one if you need it. You would want to verify that both parts are actually working before you bother. To verify that the advance and retard units are working, you just have to see if each side will still hold vacuum. On these dual vacuum units, the advance side is usually fine, but the retard side is often broken. A working vacuum advance will give you better gas mileage. The retard hose should go to a fitting on the intake air distributor that sticks straight out to the left, at about 8 O'clock and an inch or so farther forward. I advise you not to disassemble this vacuum can from the distributor if it is working now. I have a LOT of diaphram failures with these when they are disturbed and, since they are so expensive to replace, I try to be REALLY careful with them. If you want it fixed, your best option would probably be to let me do it as part of a general distributor overhaul. I should be able to find a replacement vacuum nipple here if that's what you need. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ Shameless link for search engines: http://listarchive.type3.org ~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
