Hi everyone, in a task we are asked to design and build an LC oscillator with a frequency of 8MHz. I designed it on MWO to the point where I could simulate an open-loop circuit. My struggle now is to make it a closed-loop circuit and simulate it such to plot a time vs frequency graph (which should be a sin wave of course) and in addition, plot the power vs frequency graph. Please assist me.

I cannot read all your values and I cannot tell what transistor model you are using, so I cannot actually run your project. Based on the limited amount I can see, I have the following comments:
If you are still unable to get the simulation running properly, please ZIP your project and post it so I can work on your actual circuit.
I realized it was silly to have placed a voltmeter across nothing only after sending the image. I am not sure where would be the ideal position you recommend for the OSCPROBE, could you please elaborate. Also, the circuit with the ports in its current position (see attached) works perfectly as an open-loop circuit. If I remove the ports and place a short, where then would the ports need to be placed in order to simulate, or could they be left out?
I've tried to make sense of the examples, it's just confusing me a lot more. See attached.
