I had this problem when I first learned front 2 out, but not blind 2. The trick is, is to not use the pedal to spin, instead use the pedal as a guide almost the start you turning early on the rail and then hop off and complete the rotation. Mainly just really focus on hopping out. Example: So you're on the rail and start pedaling near the end, just a little to start spinning and then hop off. I know it doesn't feel like it but when you pedal but the time you are at the end of the rail you really only have to hopp 180 out, but it looks like 270 because the motion is so quick. If the pedal becomes to much off an issue and doesn't help your situation at all just try hopping the full 270 off and implement the pedal later on when the blind 2 feels more natural.
