Correct Procedure for Doing Compression Test ? 200

Bruce - I agree with blocking the throttle wide open; it can't hurt. But with only the cylinder under test trying to pull vacuum on the manifold (all others have open spark plug holes) I've found that even a closed throttle makes only a small difference.
