So I bolted up the new ZTherapy SU's, and barely got her to start. Very weak, no throttle response. As careful as I was, I'm thinking the most likely thing is that I'm 180 off with my distributor. Any other ideas?

Paul, I moved this into the SU Central forums. If you're having troubles with the carbs after purchasing from ZTherapy, I suggest that you call their main number (on the website: http://www.ztherapy.com). They also frequently read this area of the forum and might be able to chime in with help. But, your best bet is to call.
