Hy here Melbel1! today I don’t want to bother you with copying from the manual!!!! My 750 ut nerves when it’s warm,it always has different speed between off- 500-1200 no matter how gently I turn at the stand gas screw. It only runs with Choke and immediately runs around to 5000 6000. then I play with the Chok then go until I start. Chok pure exploit at the first ampel.if I turn the stand gas screw higher then it hangs away at the gas.I hope you can me help with your experience? Would really be great greetings from Stuttgart
