Hey Rod,
Good to hear from you even if it is in the middle of Andrew's message thread
You aren't the only one that has let the magic smoke out of a 6-volt coil. I've come across several other people in the UK and Europe that were doing restorations and tried using un-regulated original top mounted coils before they figured out what had gone wrong.
The Formula 1 track and grounds are still under construction here in Austin. It will be a proper sized course for large races so should hopefully avoid a repeat of the recent accident at the track in your state. I'll probably only see races on TV though as I'm sure the price of admission would cost more than I'd be willing to pay. At least for the first few years while the facility is new and popular.
Can also say the water pumps Rod has are good for the T-16 but might need new double-belt pulleys which was the case with my set since they had the later late war/post war domed face double-belt type installed on them.
