Have a 1969 428cj. Need to know what size jets go in the carb. Car is running rich when four barrel kicks in.

if you have an original carb for the 69 428 cj Carbs #R4279 and R4280
66 primary 79 secondary
How have you determined that it is running rich when 4 barrel kicks in?

Yes the car runs fine but when the secondary's kick in it's blowing gas out the exhaust.
