Induction Heater Circuit

Please help....Having a little trouble with this MOSFET driver for a 15v induction heater coil. The only way it will start is by changing the inductance of the coil on far right of circuit and then the gates will open and close to drive the tank. Why are the MOSFETS locked at start. What I am doing wrong?

You are not doing anything wrong, some times EC responds better if there is an on/off switch to turn the circuit on.

There is to much wrong to list it all in detail. Transistors drain source upside down. Properties of diodes missalignt. The resonator was hidden after the 50uH chokes. But @BillyT is right, sometimes a switch does help to start circuits better. Check this http://everycircuit.com/circuit/5493738360274944

Thank you for your review. I will flip the MOSFETS - I Originally had them oriented the correct way and was messing around if it made a difference on EveryCircuit and forgot to put them back. On the diodes can you suggest a few settings for the UF4001 and the Zenar 1N821. The MOS is an IRF540. I will also add a switch.

Check this as Mosfet setup IRF540 all other components just take the default setup http://everycircuit.com/circuit/5574650242531328 good luck!
