Mine has 66 jets in it. Thats stock 600. Mechanical secondary and manual choke. I have the choke locked in the open position. Dont use it. I'll be out at Lakeland tonight if you want to stop by. I can try it out and we can swap there. 57 seems kinda small. Even my little 306 seems to be fine on the low end with 66 primary jets and 73 rear,.. but wants a little more on the big end than this 600 can give.
Doing the math I need 633 CFM to run 6500 rpm. So I assume thats why I'm falling short at 6000 with this 600.
If you can make the track let me know when a good time and place to meet up woud be. I live in New Port Richey,.. not far from 54 and 19 area.
My cel# is 727-919-7065 if you want to give me a ring. Jim
