Timing and fuel

[mckenzig]

A couple of questions that I would like some input on. What fuel is required when the GE handbook says Super and with this what setting is required on the timing, the standard or advanced?
Another one is what temperature thermostat should be used?

Premium unleaded would be closest. With timing just advance it a degree at a time until it pings under load, the go back a couple of degree's.

Thermostat somewhere between 80c & 90c
