Ok that sheds a little more light. Everything there except for the pull in knife edge is saying tail heavy. Usually a tail heavy airplane will tuck in knife edge. Having stabs that are out of whack could be causing that pull. The elevator trim becomes more effective when the wing is unloaded. I bet on a vertical upline it pulls too. I am in no way suggesting these are the fixes though, the fist step is to measure it out. As Bob stated, the canopy rail is usually a good zero point. Measure down from there to wing TE and LE then make sure the engine is at 90 degrees to the canopy rail. Lastly see where your stabs are. Trying to fix it before you get all those measurements is like trying to align the front end of your car by sight.
