[QUOTE="backlander, post: 140294, member: 2035"] No, that first pic of vacuum line is part of the Vacuum advance for the ECM, the 1200 ECM uses electronic advance in 1st thru 3rd gears and the gear selector switch sends a signal to the ECM in 4th -5th gear and the ECM uses vacuum advance in those two gears. Just make sure that that vacuum line has no cracks in it, mine did and had to be replaced. That's the correct port on #4. If the cover plate is thick enough to have no flex the two bolts should be sufficient along with the 0-ring. [/QUOTE]
