Just some more info the help. As I said make sure the neutral plane is right and the brushes are all bedded in properly. The series field 4 coils have 1,2,3 turns( If I remember correctly) tappings on each coil. Tuners have generally started with 8 turns(2 per coil which I think is connection 1 and 3) within the whole series field, so this is a good start. Then you can test your compounding by sending the lift to mid shaft, then kicking the lift via H and U/D to test the compounding/speed with a FPM tester( using all appropriate safety measures). This should get you out of trouble. I wouldn't think they would have changed the car/counterweight balance which can effect this too. You may have to adjust other setting to get a good s curve, but see how you go with this.
Any way let us know how you go.
