carb heat air intake question for winter running

Postby grey owl » Wed Dec 11, 2013 11:01 am

well, its starting to cool off and my season is just starting. I was out the other day and a guy commented that I had my air intake facing the wrong direction. the theory was that because the air intake was at the back of the engine and closer to the prop, the prop suck would actually create a vacuum that would accelerate carb freezing requiring me to run carb heat more often. I do freeze up from time to time but always thought it was more because of conditions and just run carb heat so not a big deal. as well having it facing that way helps reduce snow intake.
any thought would be appreciated
cheers will

are you asking if facing the carb intake backwards is causing icing?

it cant help the icing...the way I would see it is that while running the air is flowing past the intake making a low pressure, increasing in velocity and making carb ice. just like the venturi in your carb.

is the snow that bad that you will injest it and make it run bad? having carb heat on will rob you power as well.

try to turn it 180 and see if it helps the icing.
