I know Ive had this problem before but for the life of me can't remember what to do to correct it. Advancer? Swapped motors recently and everything is golden except when giving it throttle, the motor revs hi and doesn't pick up speed until I throttle full open. It jolts and REALLY picks up speed as if something is sticking. Pilots are at 3 turns out, pma ignition is at 3500 rpms and advancer snaps freely. Ideas? Thanks men!
