2nd the Bosch Duratherms. Should last several years if the timing is not overly advanced, and avoid the ether. Stay away from the Autolites, known to mushroom and disintegrate inside the head.

Warm days, you barely had to glow it and it would snap to life almost immediately.

Good sign of probable healthy compression, most important for an IDI engine.

Make sure the GP relay is seeing the head temp. signal. Usually a brown wire coming off of the temp sensor at the rear of the head, just below the rear cam sprocket. If disconnected, the open connection fools the GP relay into thinking it's max cold and requires max GP time.
