Base Timing Questions

Thanks Bewy what documents are these? Difficult to read and wouldn’t mind getting a link or copy of some sort for me to read on my own. I actually am moving towards the vacuum system, but won’t have the components for a little while still. I’m trying to make what I have work and have in the past, but trying to also understand how things work as best I can. This document might be able to help me much appreciate it Ron
If you right click on the images you can save or open them in a new window and zoom in, works a little better then zooming in on this page.
