It's a hose. I forget what it's there for. Will have a look when I get home and let you know. 1

spacesailor Posted July 12 Posted July 12 Aren't those airfilters supposed to be oiled . Likewise the foam filters . spacesailor 1

facthunter Posted July 12 Posted July 12 Breather grundge shouldn't go into an aeromotor intake. It'll pug up your intake ports and ring grooves. Nev 1
facthunter Posted July 12 Posted July 12 There's no point in oiling those coarse plug filters. They are not efficient whatever you do with them.. They have an insignificant area. Most planes have NO airfilter. Dust in the anti icing section is a risk to engine health.. If you fly in a dust storm prepare for a wrecked engine. Don't do it. Nev 1
Thruster88 Posted July 12 Posted July 12 I have yet to see a piston engine aircraft without a filter. The turbine Airtractor aircraft most definitely have filters. 2
facthunter Posted July 12 Posted July 12 (edited) They need them with all the dust.. . Some turbines have to be regularly washed out to Maintain performance.. I don't know any large radial that has any filter. A damaged (or blocked) filter wouldn't help the engine. Alcohol Spray is used as an anti and deicing procedure in the intakes and that is not compatible with a fine filter. They are fitted to the lycoming continental jiggers but they have to be regularly serviced and don't usually fly in torrential rain and icing conditions. Impact ice (Rhime) can block them.. The carb heat bypasses them. Nev Edited July 12 by facthunter clarity 1
Thruster88 Posted July 12 Posted July 12 (edited) We only look after one radial, a Beaver, it has a filter. All the certified aircraft have an alternative air supply, carb heat or a spring loaded opening. Edited July 12 by Thruster88 1

facthunter Posted July 13 Posted July 13 No I think the quote function can alter meanings. I sometimes NAME the person, IF it' s specific If it's a general statement I don't bother, because it's general. Nev 1
BrendAn Posted July 13 Posted July 13 The hose must be for carb vacuum or maybe a vent ?. It just loops over to a nipple on the carby.
BrendAn Posted July 13 Posted July 13 And how does this carb heat work.does it just warm the body of the carb. Its a flat plate with 2 wires attached to it.

It likly the carburettor float bowl breather/overflow. Its supposed to terminate in an area of atmospheric pressure thats the same as the carburettor air intake. 1
facthunter Posted July 13 Posted July 13 Venting it in the wrong place makes the mixture go for a Whoopsie. Bit of a trap for young players . Nev 1

Seeing the pictures that's exactly what it is, I have done the same except with a shorter hose that enters the opposit end of the filter near the carb throat avoiding the loop...does the same thing 2

Yea they are just a resistor that affixs to carb body near the area where the butterfly is located, as much use as a chocolate teapot imo Edited July 13 by Red 1
facthunter Posted July 13 Posted July 13 Put a temp sensor there and you don't have to guess if you're safe. Long intake manifolds are bad for icing. Actually good for icing but BAD for you.. Don't forget you can get icing in ambients of 26 c.. but unlikely at the south pole. Hands up if you know why that is. Nev 1

Nev I got caught with a 582 once. They have a vent hose connected to both carbs. I noticed 3 pinholes in the hose so I put a new piece of hose on. Pushed fuel out of both carbs when I started it. Then I realised it was a vent. 😁 1 1

Nev Because the air is dry at the south pole ? 2
