The carb is new and has never been mounted until I installed it. I did remove the the butterfly to install a different throttle shaft. I do see some light but it shows around where the shaft is. I think I have it aligned properly. I have tried numerous times to get it to touch all the way around but can't seem to. I looked at other carbs that are new in a box and they have some light showing in the same general areas. I'll try to run it this week some more and try the WD40 trick to see if anything shows up. Is there a way to align the butterfly properly? Mine is touching about 95% of the opening but like I said, I have other carbs that are showing about the same amount of light.
Thanks
