The plunger of the TA expands when the cooling fluid heats up and in this
way reduces the amount of fuel.
Running with a defective TA in "cold" position means that you will always
drive "too rich"; next to a high fuel use the bad result can be petrol
mixing with the lube oil which decreases the lubrication of the engine
(damage to bearings and the internal of the Spica pump) as well as bad
firing (damage to the pistons)
As you live in a warm country you could opt for a dummy TA that avoids the
too rich mixture (quite easy to make yourself; see i.e.
