Thanks for your input guys.
I saw an earlier post/solution in Vadrill's post and this has confused me a little.

I have the same split on the breather hose to my valve cover and I also have the same hesitation on acceleration from stop.It so happens that the "vacuum" hose for the fuel pressure regulator also connects to this breather hose at a T.
Steve - damn, I was just about to "pop" the champagne...you burst my "bubble"

!
Nevertheless, I will change out the vac hose to the fuel reg as well as the breather hose it is connected to - valve cover/intake/air filter housing.
Where do I go from here?
With the EHA off, I am still running rich and leaning the mixture till the car barely idles only results in very rough idle but still smoking.
Any ideas?
