hey guys

the plug would be good to look at
also you should be using 15% nitro and add 4 to 5 oz of clotz oil
so you have the 20% recomondation.high speed needle should be near 2 turns open and low speed 3 turn open to start with.
if while throtleling up thew engine sputters and fuel drips from muffler lean low speed 1/8 of a turn at the time but remenber you must always see a trail of smoke at hover and below,high speed as well but at 2 turns open it should be close.

let me know how it goes
