Sounds like you've done everything right so far. I'm stumped as to how this could happen. Look on your vac can arm for that number and make sure that the circlip is in position where the arm attaches to the breaker plate. You can also look at where the arm comes out of the can. There is a notch cut in the arm which limits its travel, which in turn limits the amount of advance you can get out of that can. The vac can should have a return spring built in and it should return on its own, once you remove the vacuum. The easiest way to check this is to suck on it. I use a length of windshield washer hose to do this. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
