RE: Magnum 91 FS Valve spring stuck...why?
Thanks for the answers and the conversion from metric... I will make those adjustments... I turned the needle about 1/4 turn for the first adjustment and then a little more to finalize on the .006 setting... Running Powermaster Saito 20/20 for the first gallon of fuel and considering going to Powermaster 15% nitro with 18% oil ... heli fuel....
