How much did they draw at idle each?
I just corrected my timing last night with a advanced timing light so I could finally set it.
After I set the timing, I just threw the gauge on all, they were all pulling 10 evenly. I haven't touched the idle mixture screws or anything yet. I only had like 30 mins last night, so I set the timing then cleaned up pretty much, but tonight I plan on investigating a little more.
