I was thinking and it seems I should have gainded more angle then I did. If my math is correct and it is about 52" from motor mount (pivot point) to end of tail shaft. I know the motor mount is not exactly in the center line of the crank but it is close enough for some rough figures. Then every degree should work out to .45" of movement of the tail shaft, so every 1" of tail shaft movement should be about 2.2 degress. I only gained .5-.75 degree with 1.25" change, just doens't sound right. Might be time for a new angle indicator, haven't used it in a few years. Think I will measure the front of the crank shaft and tail housing off the floor, from that and distance between the two point I can figure the angle and see it is jives with my indicator.
