Running rich is one of the classic symptoms that has a couple of standard, and cheap fixes. First thing to do is get in the car and turn the ignition ON. You should hear a relay click and then a second click about 1 second later. Between clicks the fuel pump in front should run. If you don't hear this exact sequence then there is a wiring problem. Let us know what you hear and we can go from there.. The pots on the dash are something you should get rid of and put back to normal. > The point about maybe not rebuilding the engine is well taken.

I wouldn't pull it until you get some experience with it and run it a bit. That's the only way that you'll know what it really needs. Otherwise you may discover that you're removing it a second time just to correct something minor that could have been fixed the first time around. > What books are still available for the T3's, and which would you recommend? This is the one you need to start with. It's still in print, but only early printings have the wiring diagrams in color. Used ones are out there. Volkswagen Official Service Manual Type 3 Fastback and Squareback 1968-1973 published by Robert Bentley, Cambridge, Mass, 1974 ISBN 0-8376-0057-X / LPV 997 383 / VSQU (excellent book, complete and well written) These are very good for the FI, but are out of print and hard to find: Volkswagen Fuel Injection Technical Manual, forth edition (covers D-Jetronic Type III, IV, 914) published by Henry Elfrink, Los Angeles, 1972 I may have a decent copy of each available for sale. I buy them up whenever I see them, just because I don't want them to end up in the trash. There are other good books out there, but there are lots which are not worth buying. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
