The Australian version does`nt have the rotating plug which varies the timming in steps, instead it has two wires going to a small plug which has a 1watt 10ohm resistor in it so it can be changed, what would like to know is my resistor (10ohm) the standard one and what would it be changed to to advance my timming in 3degree steps, as i`m now running what we here in Australia call Ultra Unleaded fuel which has a much better octain rating 98 i think, so i might be able to advance the timming without getting any pinging. Thanks
