When my banshee is cold it is an absolute bitch to start, I kick at least 30 times before it even wants to start and when it does it turns off within 5 seconds then I start it again, and it turns off again, everytime I start it, it stays on a bit longer till eventually it doesn't turn off.
I recorded a short video of what I mean:

Also I turned the knobs on the tors half a turn, does this idle sound too high?
