It has really horrible fuel distribution ROP but as you get close to peak suddenly everything flattens out. You can slightly help this by adding a little carb heat. I haven't succeeded in actually getting more than 15 dF LOP but if I'm above 5000 (or below 21" MAP) I'll run basically at peak with good results. Colyn
