Mk3 escort series 1 rs turbo
 

Hi, I have a 1985 RS TURBO Escort series one and was just wondering what fuel should i run it on and also, does anyone know the exact timing setting that will match with the fuel? My engine has a small ticking noise at the top and i have replaced the lifters, but the tick seems to be there slightly still. Could this be fuel and timing setting?

think this in wrong section
