What's the cold fast idle setup on the late model variety? Any chance you need to burp the coolant on the TB?

What did it cost you to have it bored and the plate made?
Taper or straight bore?


The aixiliary air valve (idle-up valve) was the reason I did all this in the first place. I figured since I was going to go that far (replacing it) I mine as well have the T.B. bored out. The air valve has wax that when heated up by the warming coolant will close the valve.

I'm positive the coolant doesn't need to be burped. It cost me around $130 to get the bore done, and they did not taper it.
