Okay, those are the 68-71 (maybe earlier, too) timing marks. You should time to the left mark (#1) which is TDC. This assumes you have the original distributor. If you have something different then you may have to start at a different idle setting. In general, the timing is set up so that the spark fires at about 30 deg BTDC when the engine is above 2500-3000 rpm. One common problem is for the mechanical advance part of the dist to be frozen up. If this happens the spark doesn't advance at all as the rpms come up and the engine will idle fine, but won't pull at all as it speeds up. This is EASY to check if you have a timing light. Just watch to see if the timing changes as you speed up the engine. It should. You can also check this by grabbing the dist rotor and twisting it CW. It should turn about 10-15 deg and then snap back on its own when you let go of it. If yours fails either test, I can fix it, but it requires that the dist be rebuilt. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
