hi there.
I recently bought a 95 Honda ballade(I'm from South Africa elsewhere its called a civic) 1.5 16v carb.

I recently replaced the timing belt and noticed a vacuum line that have been blanked off. It is part of 3 branches. One comes from the air intake to the air-filter, the other from the distributor housing(I assume it to be the vacuum advance) and the blanked off one. They all come join up and seem to enter the back of the engine (possible the carb).

My question is that I would like to know what this blanked off line is for. I see that there is what looks like it could be a connection on the distributor cap, but I'm not sure. I didn't get an owners manual with the car, I was able to download one online, but its for International models and does not include the carb model and thus I cannot determine what to do with it. The car drives fine, but I would like things to be working the way they were designed to.

Ill try to upload pictures soon.

Kind regards
JP
