MG MGA - Vacuum advance
|I got the MGA running but am still trying to figure out the many loose wires. Looking at the distributer I noticed a tube from the vacuum advance that goes nowhere. Also a green and purple wire is hanging down (in the engine department) that looks like it was connected recently. Any thoughts??
|Look at the bottom left side (as you face the air cleaner) of the rear carb (if you have SU's)....There is a little brass nut, that you will need good light to see...It has a hole in it for the brass vacuum tube...There is supposed to be a "bulb" device near the middle of the tube that has a trap for carbon, etc. If the nut-hole is open, it you will have a vacuum leak (a pretty big one, I think). So basically, the tube runs all the way across the back of the valve cover, from the dizzy to the carb...It goes under the rear carb, into the little nut with a hole in it. |
Hope that's clear as mud! (LOL).

|Green and purple is the wire from the brake switch to the stop lamps.|
