I have to run a 52-55 pilot, a 195 main, and a cel needle all the way on the bottom to get mine to run right. Its really trial and error. Remember idle to 1/4 is pilot and your idle screw, 1/4 to 3/4 is needle, and full throttle is your main. Its really really cold here (20-40) and the winter jetting is nothing like your summer jetting no matter what it is.
Oh yea, my mods are just vf3,s cool head, and a 2-1 stage 5 from trinity.
