I just installed the Pro Systems alcohol fuel system and carb. I've not made any passes yet. It doesn't appear to be super rich. I've idled it in the shop for several minutes and it didn't run me out. My carb didn't come with power valves but I've always used them in everything I've ever had. I like for it to be clean on the return road and in the pits. It sounds pretty snappy and I've always ran my stuff with smaller jets than most other people. I think I'm going to go ahead and put a lean out on it just incase. The oil I currently use is Lucas Synthetic Racing oil. Would you think that is compatible?
