Frost on th carb

Trapper D · Feb 2, 2014

It does not seem to hurt anything but was wondering if there was a way to keep the carb from frosting up near the manifold. Do I need to adjust my mix or what? Maybe it is normal. It is about 28 Deg. today. Just changed plugs and wires and was pushing snow.
I was also wondering if it would help with condensate if you left the breather cap off so more could evaporate without condensing back down into the tube? Thanks for any advice.
It is a 1949 8N , 6 volt with mag.

That is in fact normal part of the way a carb works and the atomization of the gas in a carb causes things to cool down more so yep the humidity in the air will freeze up on the carb. One way to help wit h that is a cover over the side of the engine to help hold the engine heat in. That is why many of the older cars with carbs had the tube coming up off the exhaust manifold so warm air was sucked in to the carb to help keep that from happening

I figured it was normal but just wanted to check.

It's called the venturi effect. Pretty cool thing! And perfectly normal.
