Vacum hose for distributor?
Hi all,
This is a complete newbee question, so please only laugh where I can't see it... :-) I recently got my car back with the top rebuilt. The car is a real "Frankenstein": 1972 T Targa with 2.7 engine with Zenith carbs... Before I left the car at the shop there was a vacum hose from the distibutor that went to the right carb. Now when I got it back, there is no vacum hose from the distributor. Shouldn't there be one? If so, where should it be attached to the carb? Like I said.... a comblete newbee... /Christian

The cut below is from an old thread. "search" is your friend.

Thank's for a quick response.... I actually tried to search but since my english skills is only a little bit better than my mechanical skills I faild to find anything useful.
So what you mean is that the vacum hose is totaly unnecessary? The post mentioned that it only has an effect at idle. Can this be the reason for a very unstable and sometimes high idle >2000 rpm? /Christian

So what you mean is that the vacum hose is totaly unnecessary? It's unnecessary for me because I don't have smog polution test. And carbs like an advanced initial ignition. The vacuum hose created an initial ignition retard, not an advance. Your initial advance depends on the max total advance that you adjust the distributor to.. Meaning you set the max advance and let the initial fall to what it want to. The post mentioned that it only has an effect at idle. Can this be the reason for a very unstable and sometimes high idle >2000 rpm? ------ is this happening with the vacuum hose connected or disconnected?
