Why do you need a compression tester to change the timing belt?

Well because you want to keep the car at TDC....maybe that was just for the cam gears....but still it helps.

take number one plug out and used a screw driver to determine when the piston topped out. then markers the crank and the cam gears to keep the timing. Cam gears did turn a little, one tooth maybe, just lined them back up when we put the belt on

BUT it isn't necessarily at TDC when the screwdriver comes up....I had to go around TWICE to get it at TDC.(it says that in the manual too). You may not have had it at TDC because when it is at TDC the notches at the end of the cams line up straight.
