I have a parnell system fitted to my AU mk2 Ute I get about 320 for 55 Lts in town and 360 for long motorway cruise at 100-110K/h
Also I have a intermittent problem normally just after starting and driving at low revs for 2 or 3 mins the engine wont rev passed 1000 stalls a bit when the throttle is pressed down and runs rough on tickover, usually stopping and restarting after the gas system has reset seams to work, it might not happen again for weeks or couple of hours
Any body experienced this
