I keep having the same problem for a while now. Engine runs fine but i keep getting a rich setting just after refueling and needs about 30m into the track to clean up. The same thing happens to my brothers engine.
I drive a Sirio Kanai
EVO 4 and my brother RB WS9.
Anyone knows what causes this 'problem'?
Sometimes it might flame out...unless i keep blipping the throttle for the first 10m and then take it easy for the next 20-30m and try clearing it up at the jumps.
