Edddy vacuum port advance

[billschroeder5842]

Well, I just can't leave well enough alone....

Does it really matter which vacuum port on an Eddy that you run your distributor advance to?

I know that the port on the left is "intermittent" and the one on the right is continuous. I currently have the advance set to the left or constant side.

The car starts great, runs well except this annoying bog/flutter on take off. I gave up a long time ago on the hot rod part---I'm looking for dependability with a little kick for good measure.

Any opinions?

Most all of our engines ran the vacuum advance off of the "ported" or passenger side of the carb. When it's connected to this port, it will advance the distributor when accelerating from a stop.

When it's connected to the "constant" vacuum port on the drivers side of the carb, it will be advanced almost all the time and it will "retard" the timing when you hit the gas from a stop.

I switched the ports and it seemed to make the hesitation "mostly" go away. Do youthink it might need an oooooch of additional timing? I'm currently at about 10-12.

Thanks!

Possible....first thing I would check is to make sure the accelerator pump in the carb is working when you give it gas...that will cause a "hesitation" also.

You could probably get away with a little more timing...depends on the cam profile also....I would not go any more than 15* .......

Bill, no answers for you but I am going thru the same issues with a rebuild on my son's car. It starts easy enough and runs but has definate lag on acceleration. I will be watching your thread to see if I can get any clues what to do with my son's charger.

unless you are near stock,i would not mess with vacuum advance.it causes more trouble than it's worth.

Edelbrocks are lean from the factory. Buy the jet and rod kit and richin it up. I had to go up one rod size then went up one primary jet size this solved the bog on my 440. Left the secondary jets as is. Also went up one color spring. Very easy to do. Bought mine from Summit Racing.
