Thanks John, Yes there's a cable choke only on the center carb. I've never had to use it though. Most likely because I've got all carbs running with the idle screw out approx. 1 1/2 turns and it's rich in the first place. I'm going to try closing the idle screws on the two outside carbs tonight and see where that gets me. It makes sense to me that one carb set at 1 1/2 turns out is enough for a stable idle so the other two are only used to squirt more fuel when you lay into it. Thanks guys, I'll keep you posted.
