This TVR came in on a tow truck and wouldn’t run.  Turns out it was a victim of a cheap replacement distributor rotor.   We’ve spoken of these before (see this blog post).  If you find one on your car, go ahead and get a new one, as they are problem children.  This particular rotor didn’t have very good tolerances either, so it got loose enough to hit the contacts in the rotor cap.  With a new rotor and cap, the car started and ran very well, thank you very much.
