Intro to a TQ video

Thank you for these! I watched both and will rewatch tomorrow. I also subscribed. Other than knowing what tquads are, I have never played with one. My brother has one on his 73 Cuda 340 so I would like to be knowledgeable about it if it ever needs tuning or adjusting. So my request is a video on car that shows common trouble spots and how to address them like leaky throttle shafts, adjusting the air door, etc. You sorta cover the air door adjustment in the second video.
