When something changes as it warms up it is usually due to expansion and contraction of the metal parts due to change in heat.
As that cold engine warms the super tight clearance of your valves reduces to nothing and the flow of air/fuel/exhaust changes with it.
I have noticed that everyone on this forum tends to adjust their valve clearances super tight on a cold engine. I have also noticed a lot of specs being mixed between metric and Imperial without proper conversion tables being used.
Check your valves and adjust to the proper specs. It does not matter what you do to your carb if your valves are screwed up. They every one come from the factory wrong and when people adjust them, if they adjust them, half the time they are adjusting to the wrong specs on an engine at the wrong temp.

Yep they are adjusted to .003" intake and .005" exhaust
