made 2 mods and distortion is gone

I set the generator to 600 ohms and the filter resistor to 100k. this is with 2% mod

I made these two changes. Tapping the input resistor cleared the RF amp signal and raising the filter resistor cleaned the AF signal.

This is the signal with the 47k resistor and tapped input.
One last look at a 75% modulated signal

 Looks good I may have to build this one.
