Bought a Demon from Don. Learned how to set it -sure its not 100% yet- Carb came jetted and ready to roll for my engine. A few test and tunes on a lonely highway and the car starts good has amazeing throttle response and not a hint of bog. And as a bonous everyone always thinks a demon looks cool. I run no choke on my car and it never fails to start even when its cold, I store the car for winters and it still starts good. Last winter it sat outside and would fire up at -15deg c with no issues.
