Fazer carb cleaned! Now a twin

[Slippy]

As the title says I cleaned my carbs and the 2 middle cylinders aren't combusting . I cleaned my carbs because of rough idle I found the offending pilot jet and cleaned it. A break down of what I did is:
- carbs out
- removed bottom of each carb
- removed pilot and main jet and cleaned with carb cleaner.
- carbs back in bike
- 2 throttle cables connected
- fuel line connected
- 2 coolant hoses connected
- idle connected


I have a feeling the 2 middle carbs are not seated correctly as the two middle down pipes stay dead cold while the other two get very hot. Any advice of something maybe obvious I missed ? Got a track day in 3 weeks so all help appreciated.  Thanks
