it says in the book that came with our 92 (mines a 90) to turn out the both of those 2nd screws the pilot air screw "2.0" turns out but theres only 1 and its on the left the 1 on the right doesnt and it looks different then to start her up and "set the tachometer(that there dern taco meter)and adjust idle speed with idle speed screw" but those but those ar on top of the throttle overide and i dont have those cuz i have a twist throt. it doesnt say anything about that 1st screw so what the hell
