Cold morning start up problem

Take a baffle out.

I know there is an obvious reason for you to say this but why take a baffle out? I they're all clean then surely it can't be to do with that?

I find a lot of the Riello RDB burners have the plastic air adjustment door seized or/and the adjustment bolt thread slipping. I remove the top air cover and take a look at it while adjusting air. Lots of them I have to manually push them with a screwdriver while using Allen key on air screw.
I would think highly likely to be the problem.
