I have a CHT sensor under the sparkplugs on cylinder 1 and 3.
I can see that Cyl1 gets much hotter than Cyl 3 before the thermostat opens fully
and I'm guessing that is because the flap on that side of the Engine is "closed" before the thermostat opens. To get a little more airflow on that side can I just slacken the thermostat wire a bit to let the flap be a bit more open untill the thermostat heats up and de-tensions the wire fully?
Or am I thinking wrong about how it moves?
