I just came across a calibration kit for a 1406 on my shelf. If I could, I would like to keep the carb that is on it and put some miles on the car first before I start up grading it etc. If I give up a few HP so be it for now.

I will have to read up on this carb this weekend since I haven't had to tune this type of carb before.

So, you think I may be experiencing a lean surge type condition?
