Loss of power after adjusting the valves.

[Elripster]

I decided to adjust my valves this last weekend. Well the first time through I didn't do such a good job. The motor was hot, likely cooled too much in the process, and I just wasn't very good at it. As a result the car ran like crap.

Today I did it again with the motor cool and really took my time. The engine runs much more smoothly, idles more smoothly, but it isn't as fast as before.

When I originally checked 'em, it seemed most if not all were too tight of clearance. Now they are as spot on as I can get them. I double checked them and was very meticulous. I just can't quite understand the loss of power. Any ideas?
