We set ignition timing during build. What initial do you want? rotate engine to that point before TDC and rotate distributor so the points just open or reductor in line with coil. This will be close enough. Test fire distributor for spark before installation. On the run stand or cars system before hand. On day of firing, Use a test distributor to test ignition system again just be for cranking. Good spark you are ready. We use an electric pump through mechanical. After initial run, you can turn it off to ensure pump is working sufficiently.
