Yes my carb was built for my old set-up then sent back to him for my new set-up and still does the same thing. Dealing with Patrick has been a pain for me as it is always"send it back to me and I will fix it" well that sucks. I will just try to fix it myself or deal with it till race season is over then i will send it in to him as I'm tired of waiting and paying shipping costs for an issue that has yet to be fixed!
