[Bmcu] Anybody got a Colortune?

[Ryan Border]

Gentlemen-
   New list member here, having just put my British car back on the road-

Here's my car:

Here's a little video, shot earlier this week driving it up in Butterfield Canyon:

I'll make a long story short, and just say I need to do a total carb adjustment on it.   Among other things, I need to get the mixture set for the local altitude (the car came here from Kansas).    To assist in that effort, I think a Colortune sparkplug would be helpful.   Before plunking down close to $80 for one, I thought I'd see if any of the local Brit Car guys might have one I could borrow for an afternoon of tuning.   I'm pretty sure my head ('83 XJ6) would take the standard 14mm plug size.

Thanks!
Ryan.
