[ercoupe-tech] Winter flying

[jrusselkoch]

As winter gets closer I still want to go flying, but now I need more heat. On 
the front of the Ercoupe, 1946 I have 4 holes. Two for the cylinders, one on 
each side, one for the carb, at the bottom of the cowl and one more just below 
the prop. Can I restrict the flow in any of these to gain more heat, and if so 
how. Thanks
