Vacuum lines with electric wipers?

This is for my '56 Pontiac Star Chief (4bbl and Strato-Flight Hydramatic).....
A few years ago I switched it over to electric wipers. Just wondering how the vac. lines should be running and the configuration for factory electric wiper cars.
It hasn't been running well, especially when shifting 2-3 it really bogs down, but is strong as RPM's pick up. Thinking perhaps a vac. leak or insufficient vac. for the advance. I could be way off though.
As it is now, I have the single action fuel pump installed. I removed the line from pump to wiper motor. I plugged the line from the pump to carb at the fuel pump side. I left the line connected from carb to distributor.
Also when setting timing with a timing light, should the vac advance be disconnected, and both lines plugged?
Thanks fellas!

If you have the stock power brake setup, the vacuum from the dual action fuel pump goes to the plumbing under the battery tray for the brake vacuum tank. Manifold vacuum to the distributor advance. Everything else, plugged capped or removed.
Electric wipers are the way to go! Especially if you happen to be driving in the rain or snow. Good luck.

Re- read your post. The plumbing by the battey tray has a check valve inline for the vacuum tank. If that's not working right, that may be where your bogging originates.

It's manual brakes......shoulda put that in there. Also, gonna be switching over to a mech. advance within the next couple days I think. No vac lines at all then, right? I really just need to verify that the line that used to go from the vac. pump to the carb isn't doing anything that the carb needs to run well!
Thanks!

Outside of a hipo race type rig or a stationary constant speed engine I would not reccomend eliminating the vacuum advance on the engine. The vacuum advance is there to sense load, and the mechanical advance is there to sense engine speed. The load on the engine in conjunction with speed determined the best advance point and when you eliminate the load sense side of the system your effeciency also falls off. Go back to basics and figure out what is wrong with the current system. I doubt that it is the vacuum advance or you would have delt with it when you went to electric wipers.

no neat sig line

 

So a Mallory dual point is a bad idea?
The fact that it's bogging down mostly with a load is precisely why I suspect the vac. stuff.
Until recently I lived hours away from where it was and haven't been able to drive or work on it much. Still dealing with fixing things I started on years ago so I'm just now getting to where all the vac. lines would be running on a factory electric wiper car!

 

man i have the same thing in my olds this is good to know

 

Put that Mallory in and she's running great! My problem was either vacuum leaks in the lines I removed (no vac lines on the car at all now!) or the vac advance. Still need to fine tune the timing but all hesitation is gone!
Thanks for all the advice fellas!
