The second spring comes into play in the upper RPM range. This is the way they are supposed to be. You can see the advance curves in the Bentley manual, which you will want to purchase.

The most reliable setup would be the 67 dual Solex carb setup. Be sure to get EVERYTHING, including the air cleaner and the throttle linkage. Some of these parts will be hard to find. Going to aftermarket carbs is another possibility and there are as many opinions about those as there are carbs. There will also be a long "learning curve" as you work thru the jetting to get everything actually running right. If you go this route you will also need to buy this manual, since the Bentley does not cover carbs. VW 1500 & 1600 Type 3, 1963 thru 1973, Haynes 084 (US) by J H Haynes and D H Stead published by Haynes North America, Inc, 1974, 1987, 1989, 1993 ISBN 0-900550-84-8 You won't be able to use the FI pump unless you put a pressure regulator on it. A simple mechanical pump is the easiest. If you go with any kind of electrical pump you will want to install an impact switch which will shut the pump down in case of an accident. The FI had such a system, but it's gone now. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
