My 300ex has an open air box mod with k&n... stage 1 Hotcam.... .20 oversized piston... close to stock cmpression..... Promod rectifier..... full DG exhaust.... Im running a 40 pilot and a 145 main... 3rd notch... fuel screw 2 1/2 turns out.... altitude at 1,000 feet above sea level...
at full throttle she hesitates real fast right after a shift..... i dont hear a backfire... but she hesitates somtimes....
I pulled the plug and the tip is a light gray and everything else is black..
should i try to go to the 4th notch on the needle or leave it and goto a 148 or 150 main?????
