Hi Aldot, Apart from the backward spring,it looks to me like the metal tab where the main governor spring is hooked on is bent too far out, thus causing a little more tension on the spring than you'd like in the idle position. Bend the tab back towards the carby and this should reduce your idle rpm, although it will also bring down your top end rpm. It then becomes a balancing act; pull it out for higher rpm's, push it back to reduce rpm til you find the happy medium.
