Milwaukee Job Site Radio AM-FM #49-24-0200

Customer brought in this radio to repair. He had it in a box with all parts. Put it back together and tried it. FM reception was far from complete. Lots of buzzing. Audio level not so good. On the main board are two sets of wound coils. one is ninety degree apart from another one. No ferrite core. Is there an easy way to tune these coils? I find that inserting a piece of paper in between a coil I can change the frequency of the tuning range, but still cannot get into the proper range 88-108Mhz. Have no idea what the inductance is. coil is about 1/2 inch long diameter is less than a quarter inch. wire looks like about 30 ga.
