i bought a 2000 srx with a wacked engine, then i bought a 99 srx 700 motor to put in the 2000, i noticed now that the part number on the cases are different, i installed all the 2000 ingnition in the 99 motor and cant get spark, every thing test out ok,stator coils cdi etc, does any one know if the caases were diffewrent on the mag side, seems like the flywheel may not be close enough to the pick up, any one know thanks
