A 1993 Chevy does not have a carburetor, it is fuel injected.
If it is a V8 (big or small block), the firing order is 1-8-4-3-6-5-7-2.
The tire size should be P235-75R -15. I have a 1998 Chevy Cheyenne 1500 4x4. Tire size is 265-75R-16
Firing order of the 5.7 Liter (350) Chevy is 1-8-4-3-6-5-7-2 Rotor turns clockwise.
Assuming this is a 4.3L engine the firing order would be 1, 6, 5, 4, 3, 2.
