Ok I got a few minutes today to do another needle and seat ( because I needed a mower in a hurry) and it seems to be working perfectly, I will mow a lawn tomorrow with it and see how it performs. If it works as I expect it to, I have a fix for every problematic component with these carbs. This needle I turned down to 4mm diameter and I have the lathe set up so I will turn down 10 or 20 tomorrow depending on time
