After installing my AFR I've noticed that the carb leans out really bad when you jump on the throttle (like to 21 AFR). I previously thought it was bogging down to over fuelling but obviously not. If i put the choke on about 1/4 it solves the problem but idles rich, usually it idles stoich right on 14.7. So I'm thinking it might be a partially blocked jet in the secondary throat? I'm not very experienced with carbs so some input would be great.
