Did your cabin heater make a difference?

I have a system similar to the Skydrive on my Rotax which had 60 hours on it from my other plane. I left it on since there is no drop in performance, when I installed the Rotax in my RV12.

I made a aluminum baffle that I slip into the gap between the radiator and the seal (copied one someone had posted ) and it helps- can move the CHTs from 140s to 170s on a cold day like this weekend and allow some heat into the cockpit- when OAT is below 10F, it does not get very warm.

Default CABIN HEAT - -

I flew Saturday morning, and it was about 18 degrees on the ground, and colder at Alt. With my "Heater Damper Door" system, I run the CHT's up to 205 - 210 degrees to get some real heat. Best mod for comfort in colder climates. I would have to believe that running the engine as warm as I do in cold weather, it helps with no carb ice.

Somewhere in the past I remember reading that carb icing is most likely at temperatures near but above freezing in high humidity. In really cold temperatures (below freezing) there usually isn't enough moisture in the air to make carb icing an issue. In practice I always applied carb heat in the Cessna 150/152 when reducing to idle, and I always apply it in IMC on my Cherokee.
