RT84 1700cc 6R Year 1972 Carburetor

Post by ToyotaCoronaRT84_Portugal on Fri Mar 31, 2017 2:34 am

Hi Everyone!

I need some help.

The previous owners of my Corona decided stupidly to remove the original Carburetor and replace it with an electric one.

Result: the fuel injection at low rpm is incorrect. The carburetor swamps the Engine with too much petrol and the car keeps going off frequently, when sopped at a traffic signal for example.

Just to help, apparently this 1700cc 6R Engine version was not produced in large scale, so it's almost impossible to find an original Carburetor in the second hand market.

For the manufacturers to help me, they ask for photos of the original Carburetor and/or the OEM reference stated in the original part, which I don't have.

Given all the above, I seek your help.
Please advise If you know any vendor/supplier that has this Carburetor or, in case you have a similar Engine version, if you can share pictures and the OEM reference.

Thanks and Cheers!

Ill try and upload some pictures before the end of the week, I have a service manual and my original 18r carburetor. have you tried to change out the fuel jets in the electric carb? or any adjustments. its probably getting too much fuel at low rpm
