Thanks for responding. It sounds like they need to be gone thru, rebuilt, jetted...ect. I'm actually looking for one that has been cleaned, and gone thru with new internals ect already. I also do not know that much about the Dellorto's either hence I wanted to find one that has been already done and ready to bolt on. I know the value of these carbs and ready to pay up for what I'm looking for.
Cagun Cowboy gave me your name in the hopes you might have a clean altogether Dellorto MB22A carb for an H50 engine. I have a '69 Roadster as well and would like to install a MB carb on it. If you don't have one, he thought maybe you knew of someone who does. Any help would be appreciated!
