All too hard and probably not worth the effort, I'm just happy for me to have an fix for any of the mowers I work on. I used to get so annoyed every time I knew I had a needle that wouldn't work and there was not a thing I could do about it I could spend hours trying to find one that would work taking the cap off other carbys, fitting new ones was a waste of time and then there was the issue of how long it might work for. Needle stick in the seat and it was all over. At least the brass ones are heavy enough to always drop down with the float. Hopefully I will never have to think about this problem ever again
