Moisture on outerside of Carb
 

What causes a carb to sweat? I have water droplets coming off my carb when cruising.

It comes from the air speeding up as it gets sucked thru the carb. If it is humid out, the carb body temp will drop in relation to ambient temp and water drops will form on the outside.

I used to have a carbed blower motor and on hot humid days, ice would form on the carb due to the high velocity of airflow.

I think, as the air and fuel are drawn through at a relatively high rate they cool the carb and intake down much lower than the ambient temp, drawing the moisture out of the air which then condensates on your gear.

Way up in the North, we get ice forming if running late or early in the season.

You beat me to it! :D

Does this indicate that the carb is tuned in? What Smitty says, is this like a little chiller?

I think you need to read your plugs or use an O2 sensor to determine that.

You can have it tuned by Dean Nickerson, I did and I only needed to make very minor adjustments to get it perfect. I highly recommend it.

What i mean, with the sweat dripping off the carb, is this normal? Why are most of the carbs out there dry on the outer base. Is something not right that I need to be aware of.
Thanks for helping.

What we are saying is that this is a normal condition.

This is not something that can be used to tune your carb/engine.

Reading spark plugs or having a live oxygen sensor is the only way to see if your carb or efi is set properly.
