6 pack choke adjustment

[boss429kiwi]

Hi

My 6 pack Superbird choke setup is stock.
It closes nicely when cold and opens when warmed. However it only opens to a 45* angle.
Once warm the idle sits at 800-900 rpm, but when driving on a hot day, the idle would sit at 1500rpm and seems rich.

How do I adjust the choke, so it is fully open when hot?

Thanks

Two things that can give you that condition are non working heat riser and blocked or restricted heat cross over in the intake,check that first then adjust choke thermostat accordingly.
