in which case, you have a traditional carburetor. your "electric choke" is a bourdon spring type choke breaker. if the linkage is stuck or slow to close or the spring, the choke plate does not close. it is not "electronic choke". the heating of the buordon spring allows it to open gradually as the heat of the bimetallic element is heated.

i bought it brand new, could it be defective? the heating of the spring is generated electronically when i switch the ignition to 'ON'? did i get it right? anyway, i'll bring it to my supplier and have their mechanic take a look at it. i'll let my engine cool before i start it up. thanks.

by the way, will the fuel (i.e. caltex,shell,petron, etc.) used have an effect on my hard starting? the caltex silver fuel which i'm currently using seems to have a lot of additives as my fuel filter and carb has reddish "mantsa".

i've just had my carb checked by my mechanic, the auto choke is working, he adjusted the idle rpm and the car started better, though when the rpm went up to 1000 when the engine warmed to working temperature. am still looking for any suggestions to get better fc... any suggestion would be greatly appreciated

just an update... my supplier replaced the carb i bought and i installed this last monday... engine ran smoother... but hard cold starting again... actually worse... left it with my mechanic and he noted that it seems the carb injects too small an amount of fuel... need to pump the accelerator pedal several times for it to start... what can i do to remedy the situation? help

priming the 2E carb is a must before starting. no electronic controls just an accelerator cable. E10 only made it worse. also the fuel pump is mechanical and the engine has to be running for gasoline to flow to the carb. different from the gli that is fuel injected with an electric fuel pump that starts to pump the moment you turn the ignition on. before the fuel injected systems, electric fuel pumps provided better pressure thru the fuel lines for twin carb set ups.

I had a hard time cold starting my dad's 2E engined Corolla. It turns over and runs but dies right away when the gas is released. He told me to turn on the aircon before releasing the gas to force the revs to go up.

Ganyan din sa bigbody ko.. hard cold starting.. Ginagawa ko nlng.. Bago ko paandarin tapak sa pedal 2x habang nka on ung ignition.. den start...
then, naka tapak lang ako sa gas pedal for 20-30 secs ng magaan para hnd mamatay ung engine den aun.. ok na.. kahit bitawan ko na ung pedal hnd na namamatay ung engine..
