Looking for advice.Needed more speed last year for oval racing so I
fully advaced the ign. timming.Never checked timming till this year.
Engine timming is .120 thousands btdc.The manual I have wants .095 btdc.At .120 is this too far advanced and will it help or hurt performance? Stock 440 f/a. Fuel was 92 octane mixed at 40:1 Amsoil.
Plug color and piston wash looking good.Pugs are NGK BR9EYA.
Timming k4402rs
