Hi All, If you've read any previous posts, you know where I'm with certain adjustments. This is a good one. During a normal timing job I have always disconnected the vacuum line from the distributor to adjust and set my curb idle advance. This is what my manuals state.
Ok, Since I've now switched to manifold vacuum, which always supplies some suction, do I need to adjust the timing using a connected vacuum tube or just keep doing it as the books suggests?
