To do this, you remove the EHA from the side of the fuel distributor.

I had to turn my one a quarter of a turn CW to richen it up and the car runs really well now; no more hesitation when cold...

I will give this a try when I have the time in the next few days. I very much think the problems are coming from the EHA, since it is what adjusts for acceleration enrichment, which it seems my car is lacking.
I'm curious why it would go out of spec though, and I wonder if there is something clogging it?
