Thanks guys, mabey i should just try to get it running the way it is. In the World Models Groovy 50 3A, which is what the fl is in, the fuel tank is kind of fixed. You can't move it anywhere else than where it is. Last time I looked the centerline looked pretty close to perferct. What do you guys think the stock setting for the airbleed carb is, any tips for tunning it? Imagine starting from scratch and you have no idea where the stock setting is. I am going to give it one last tunning attempt tomorrow.
