Here's a tip for those that don't know. Don't clean your carbs in rainy high humidity conditions. Here's why: everyone who has ever used an aerosol can of carb cleaner knows it gets cold when you spray it and it makes whatever your spraying cold also. Well what does humid air do when it hits something cold, that's right it condenses and now you have very tiny droplets of water in and on your carburetor. The fix, after there all clean take them into a controlled environment ie: the house and allow them to set and acclimate. The droplets will evaporate and you can then reassemble.
