Sync Question

[MONTREALMAX]

While I was syncing the carbs with the Morgan Carbtune yesterday I would get all four lined up and then blip the throttle and the the balance would go off between left and right banks....does anyone know what is loose or worn that is causing this?

I would star with throttle cables. When's the last time you lubed them and cleaned out the junction box?

 

[MONTREALMAX]

I lubed the junction box with a little white grease and it is clean
can I adjust the throttle cables to correct this?

how many times did u blip and they go out of sync? keep going the same way? did the adjustment screw stay the same as well? is the screw all the way in or out?

 

[MONTREALMAX]

one blip throws it out, not a big amount but out enough
the adjust screws do not move

does it keep unsynching the same way?
