thanks x 2. i will try and work through this with the help that i receive from god folks like you. rod w.I feel your pain but my best advice would be to go back to the original carb. I did a lot of research before deciding to rebuild mine and even ordered a weber from somewhere but decided to send it back after reading what I read. Probably very difficult to go backwards for you so hopefully someone on here can give you some better advice than what I have to offer. Good luck.
