What is the motor and combo this is on?

If you've already got the .143 secondary jets are you SURE that you are lean on the secondaries, then I would limit the travel of the secondary flapper door. There is a tab on it that you bend with a screw driver. If doing that doesn't help any, then I would consider drilling out a spare set of jets to the next size up.

The secondary door tension spring on the side of the carb is usually what you end up adjusting to help cure bogging when you floor it.
