Hi, I have a Webra 55 P5. smilie I am not sure if it applies to your engine but what I did, also without instructions, I started with idle needle open 2 turns from closed position and high end needle open 2 turns. This got the engine started. It was spitting fuel out of the exhaust and bogging terribly. smilie smilie I leaned the high end needle to the point where it stopped spitting fuel and then it was a case of run engine,tweak.....run engine,tweak......etc etc. Finally got a stable hover then, hover,tweak........hover,tweak........etc etc. Now it runs beautifully, ticks over nicely, flys smoothly and powers like a maniac.
