sorry man lost track of your thread... it has to be metal because the expansion of the metal has an absolute minor role in the transfer of the heat...
this is how it works... as the exhaust gas travels out the exhaust some of it goes up the choke pipe, as the exhaust gas returns to the carby it heats up a metal rod/pin within the choke as well as all the metal around it... now as the pipe heats up and expands it therefore allows more gas/heat to travel to the choke which in turn opens it faster (but it is covered with a rubber hose as to prevent heat loss to atmosphere VERY IMPORTANT, you want the heat to rech the carby and not get lost on the way there and end up cold at destination WHAT A WASTE OF TIME IF THAT HAPPENS)... now as the rod heats up it obviously expands but it is situated in an area where it can only expand upwards more than outwards... although the whole carby is expanding from the heat it is dismissable to the whole effect cause the metal material this expanding rod is made from expands faster than the carby... as it expands it pushes the air inlet valve pin causing the air intake to increase as the circular valve turns... but this will cause the air going down the carby to be hot and you always hear everyone wanting cold air going in, however you DO NOT want cold cold air going in as it wont combust like warmer air does... you need to find a middle point between too hot and too cold and thats where the metal material plays its part and to prevent the air going in geting too hot, then the exhaust pipe running to choke gets blocked off by what you could call a stopper which is part of the choke rod i mentioned earlier... as the rod rises, this stopper also rises and blocks the exhaust gas entry point stopping the gas to continue to enter but the gas will still try to travel through and that allows the stopper to stay hot and raised and continually blocking more gas/heat getting through... as i mentioned all the materials used are designed for perfect temperature conditions and therefore that allows the air going into the carby to be the right temp, the carby itself to be of good temp and when it all meets up at the combustion chamber it is a good combustible temp too
now technically the choke is just used as the car warms up so that there isnt too much fuel or air going in while the car is cold but that adversely affects the rest of the carby functionality as i just mentioned
SO BASICALLY AT THE END OF THE DAY YOU WANT METAL AND NOT RUBBER but i thought the background would help you in future cause this concept is used throughout the whole... what you should always consider is this:-
- the thing being change/replace/gotten rid of or whatever the case maybe, what is it used for? where is it connected? why is it connected there? what goes through it? what is the ppurpose of what goes through it? AND what possible/probably/adverse affect does it have to the surrounding area
in the case of the choke it governs correct air/fuel mixture at certain temps (main reson for having it), but also adversely keeps carby at good external/internal temp, air intake at certain temp, ie, it was designed for one thing but affects it surrounds too and toyota would have taken that into consideration when designing and building/manufacturing the car
also like the radiator fan... it sucks the heat from the radiator but at the same time it also keeps the engine bay and external parts and external of the engine cool by helping to circulate air around... designed to aid in cooling radiator, but also helps keep the bay and engine cool externally, while the coolant keeps the engine cool internally
EVERYTHING IS INTERCONNECTED, EVERYTHING IS CONNECTED WITH SPECIFIC MATERIAL FOR A REASON AND NOT CAUSE IT LOKS GOOD OR THE FEEL LIKE IT OR WHATEVER!!!!!!!!!
finally i know this is alot but when i help i like to really help and i hope this does
