Not much improvement
I alignned the pot today, the best I can put the pot position while monitoring test points 1 & 2 is 0.400mv. Does polarity matter? I had the negative on Tp 1 and positive on tp 2 and this is how I got 0.400mv. And 1 & 3 is 5.0v.
I spent about 2 hours messing around with the mixture screw, but still can't get the idle down to 1000rpm and stable. I guess I have to live with it at 1300 RPM. May be with the low compression on cylinder number 2 is giving me this headache.
One more thing, I have yet to do is replace the injectors and perhaps the idle control valve.
