Hi Peter, took it back for the 800k check and seems to be quieter or maybe I am just use to it. Dicks stuffed around with the mixture screws on the Holly and it was running like a piece of crap but I fixed that when I got it home. Runs a bit rich on my {your} settings , 2 turns out, but I think the only way to fix that is to invest in some smaller jets as Dave has done in W.A. Otherwise it pulls great and seems to have plenty of grunt. Have to fix the throttle cable as well as only getting 3/4 throttle. I am making some new mounts for the cable to get rid of the three right angle turns which should make it a bit lighter on my foot. With new mounts I will have a gentle turn to the left, only down side is it will have be disconnected to remove rocker cover. Not such a great hassel though. Still have to paint the front spoiler but that can wait as I am too busy on weekends driving around. In the Z of course.
