I need help yet again please!! - It's to do with the over-complicated carb on my 1990 Sportrak. I'm only getting around 60 miles from 20 litres of fuel - should be more like 90 to 110 or so I think. There are no leaks, no sticking brakes, and all hoses etc are connected and tight. My bank balance is going down fast!! - All ideas to quench its thirst will be most welcome..Thanks.
