I have a 7028213 carb that I rebuilt. It has 46 primary metering rods, 71 primary jets and AN secondary rods. I took the carb apart, soaked it and cleaned all of the passages with carb cleaner and compressed air and epoxied the plugs. I bought a rebuild kit from Napa which included the accelerator pump, check ball, needle and seat, float, vacuum break and gaskets. I put everything together and set the float. I bolted it onto my 350 and pumped the throttle lever. It shoots a nice even stream on both sides. The carb idles kind of rough....The engine roams while idling around 900 RPM, which is different than my 7029202(42 rods, 67 jets, AN secondary rods) carb which idles smoothly at 700RPM. I pulled the plug from my manifold vacuum source and the engine died. With my 7029202 carb the RPMs would increase if I pulled the plug. While idling the vacuum gauge roams(with the idle) between 13 and 15 inches. With the 7029202 carb it is a steady 15 inches. While adjusting the air fuel mixture at idle the passenger side screw changes the characteristics of the engine, but the drivers side can be screwed all the way in with no impact. I took it for a test drive.....Everything seems OK until I get into the secondaries....it bogs. I figured that was because of the bigger jets?
Given the roaming/rough idle and the symptoms given above anyone have any suggestions to fix the 7028213 carb?
