As far as i can tell i am following this circuit, although different components. However, when connected to a DC supply, both LEDs light up dimly and there is no oscillation. It appears that the drains of the MOSFETs are connected together via the inductor and the Vgs of both MOSFETs are constant.
Without the LC tank, only one LED lights up, so I assume that means the MOSFETs are indeed working.
The components I am using are as follows:
MOSFETs: IRFP260N
Schottky diodes: UF4001
The resistors are normal 0603 SMD resistor, all values are as shown above
The capacitor is a MLCC, all values, are as shown above
The inductor is a toroid inductor, all values are as shown above
