I was wondering if a good basis point of 780 rpms, 10 degrees tdc 17 inches vac, and idle mixture screws at 2.75 turns from seat is a decent starting point for a test drive. I am not flooding out anymore nor stalling. I did have the vac advance line plugged. I also seated a screw tighter for the contact point of the accelerator pedal line. Before the screw never met the contact point. It basically kept the idle stronger when in park. Just wondering if it might be time for a test drive??? Still no electric choke installed but the farmer's choke is working pretty decent. Any other things to look for from your guys experiences would be most helpful. Thanks,also this was my best vac measurement as I tried a few other settings
