I am running into the same situation except I am bone stock. I found out my tors idle screws were broke and then after tearing apart someone cut the TORs cable to the throttle. Anyway, I have fresh gaskets and top end with tors removal. Made sure slides were in correctly, choke tube in, jets and needle set for elevation and still having issues. I am working from another thread and getting some great feedback. If I stumble on something I'll be sure to post for you.
