Re: CNS Carb. Question.?
I think Sportscarpat nailed it when he responded to you on the other CNS thread... "if you've had the same problem with 3 new NT carbs... the problem is probably not in the carbs!" You should check for other problems instead of the carb.
If you can't get your engine to run right with the simplest carb on earth, you're gonna have a lot more trouble with a more complicated carb.
