squonk 41,133 #11751 Posted June 4, 2021 (edited) Your low humidity confirms my theory of the elbow absorbing moisture from the cooler shop and releasing it out in the warmer air. Carburetor icing is the same effect. Cold air drawn in can't hold it's moisture and it will deposit it on a warmer surface(carb). If the air passing thru is cold enough it will form ice.

The ice would form on the top choking off the air actually. Moisture would "Fall Out" of the cold intake air as it hit the warmer carb. Then it would freeze from more cold air air hitting it. You have to understand relative humidity. Cold air cannot hold as much moisture as hot air. Relative humidity is a reading on how much moisture the air is holding relative to it's temp as opposed to actual humidity. On a hot humid day the RH may be 55 at 90 deg. when the air cools off at night to say 65 The RH may go up to 75 with no actual increase in the amount of moisture in the air. That's why you see dew and fog the next morning. The RH climbs as the temp drops until it reaches 100%RH. The air cannot hold the moisture so it forms dew and fog. When you watch a weather report during hot humid weather the weather person will talk about dew points. This is the temp where the air will start forming dew based the RH. The higher the dew point, the more uncomfortable we are. Our bodies cannot evaporate sweat because the air won't accept it. So the cold intake air hits the warmer carb. The RH changes so fast the water will form on the carb. And before it can absorb heat from the carb and evaporate it will get cooled quickly and freeze on a bitter cold day. That was part of the reason for warm air intake systems on cars. It just a strange phenomenon. But yes fuel charge should be cooler. 3 Share this post Link to post Share on other sites

The evaporating fuel cools the venturi, or jet area where the fuel is exiting into the air stream. When the incoming air hits that cold spot, if it is colder than the dew point, it will condense. If it's cold enough, it will freeze to ice. If not cold enough it will simply form water droplets that get sucked into the intake and generally that's not enough to cause issues with running. It's the ice that forms around the fuel entry point that causes a problem. Pilots are very sensitive to this issue. There are many charts on the interweb. 1 Share this post Link to post Share on other sites

squonk 41,133 #11756 Posted June 4, 2021 Yup my mistake. The problem on my example happened on Chrysler 2.6 minivans. We had to install a heat stove on the carbs to keep them from icing on the highway at sustained speeds. Put them on in the fall. Then in the spring we had to take them off because on hot days the fuel would boil in the carb bowl. One of Chrysler's "better fixes" 1 Share this post Link to post Share on other sites

Am I reading the graph correct, that you can get light icing when it's 95°F and 50% humidity? If so, that's pretty amazing. Share this post Link to post Share on other sites

If so, that's pretty amazing. In theory, yes, but it's very unlikely. But if you were 5000 feet in the air you would want to be acutely aware of even very slim possibilities!

Wheel Horse 3D 3,795 #11771 Posted June 6, 2021 (edited) Little more E6000 on Dugs seatback logo, use the old heat gun to remove old traction tape, bit if wire brushing, and install new foot board traction assist coverings on Dug...removed his navel appendage(hadnt really messed with the Tachmatic much before, slicker than greased owl snot in the rain!) now ready to start pulling tires and weights for painting!

ebinmaine 67,546 #11773 Posted June 6, 2021 Had our friend @OldWorkHorse Steve around today so I could give him a hand changing the rear wheel seals on his Ariel's Flowah Powah tractor. He'd been pouring the Liquid Wrench spray to it for a couple weeks or more and the seals were pretty much not there so plenty of lube was getting in the hub. I was pleasantly surprised to have both hubs fly right off using my "spare hub as a puller" method I picked up from around here somewhere. Even better... He also gave me a hand pulling both hubs from a spare 8 speed that may end up in the C-160 Tecumseh engine tractor or as needed for whatever horse. Also from the 3 speed that I'll be rebuilding for Trina's Military Tribute Tractor. I'd been soaking the 8 speed for at least a year. Trina started spraying the 3 speed hubs a few weeks ago. All four came off!! Certainly took more effort than the ones on Steve's but it was great to see them slide out without serious issue. Here is the 8 speed on the bench, 3 speed on the floor, with the puller next to it. 9 Share this post Link to post Share on other sites
