I wish I had some words of wisdom for you Rob! I know I have a Weber and it works great when it's cold out but still has a horrible stumble at part throttle. If I could have used the stock carb without all the darn hoses I would have been better off. Oh well. I'll keep my eye out for info, the only thing I can tell you is that LCE sells smog legal carbs but they are $$$. Still, it would be new.
