Thanks for all the threads on similar problems. I finally found the source and solved the problem. EHA was off by about 1/8 turn, I think CCW, the little 2mm screw has no friction. I wasn't prepared for that and I'm usde to making sure an allen is seated so I moved it maybe 1/8 turn to start.

First: I learned how to test everything that effects idle and timing. Everthing tested good. The only way I could get the idle from 950 and timing from 20 to 25 was to lean the idle and take the vacuum off.

I finally took a close watch on the EHA current and it was +3 at 2500. I took two 1/4 CW and idle stayed high and the balance worse. So I went back 1/2 and another 1/4 and got lower idle and timing but balance between idle and 2500 was alittlle off. Another 1/4 ccw and idle/timing went lower now easily to 600 and 10, but 2500 current was -6. Back one 1/4 and 2500 current was -3, but I could get close to balance with an idle about 800 and timing about 20. So one more and I over shot a little. So 1/8 back and amazingly with just a little mix adjusting the balance was was overlapping and current was tight around 0 both 2500 and 700.

Timing is 5 with no vac and 15 with.

Sure glad I didn't go in swapping. Would have been faster if I had parts to swap... And thanks I've learned a lot.
