Fuel requirements at tick-over

[axolotl98]

Is there a figure (plus-minus) that is about right for the 115 2T mod. 1991 ?
Sea-level & temperatures in the range of 15-30 Celcius (59-86 Fahrenheit)
It can go as low as 4.5 lt/hr (1,19 g/hr) up to 7 lt/hr (1,85 g/hr) without any obvious change in the engines performance...
Rodbolt ?

nope, set the carb needles by spec and it works correctly or its broke.
