hard start issue when hot

When you wire your msd for ignition feed, pull the blue and brown wire right off the ignition switch. Remember the blue is ignition but it is not hot in start. Only the brown is. When motor is warmed up, And if you are still asking for msd to see start voltage after the wire is running all threw the dash with 45 year old wire. You are asking to much. At least 2 volt drop just going through fire wall.
