I hate to say it because I love carb, but if you really need a no drama cold start just swap some 22re EFI stuff in there. You can get it cheap off somebody doing a 3RZ swap. You need the harness, ECU all efi stuff including the 02 sensor and the fuel pump, but it will all go on in that '85 no problem.
My kid has a '92 22re and it starts no matter what.
