okay guys , so i just started her up now , vibration seems better , but now i have another issue !!!! ,

when it idles , it idles fine , if i bang the throttle up it dies out , if i increment slowly up , it almost dies and then gets going , with alot of smoke , !! and spitting nitro all over my plane , then when i bring it down to idle again , it dies out !!!!!

this cant happen during flight !!! please help , could it be mixture to rich or lean ? bare in mind the motor is 8 years old and only now has been started
