When I pulled codes on my car, I got code 33 (Main system in relay). I have no idea what that means...
Can any one shed some light for me please.

Feedback codes refer to the duty solenoid in the carburetor and the related sensors. The computer referenes the O2 sensor to adjust the duty solenoid in the carb which (essentially) adjusts the main jet. It's a variable carburetor designed to be more efficient, the problem being they're all broken by now which makes them run very poor.
slomojusty you need to resistance test the duty solenoid and check the signal from the O2 sensor before you can go any further into diagnosing this.

Do I need to pull my carb apart to test my solenoid?

Do I need to pull my carb apart to test my solenoid? No. You can test it with carb still in. Remove the air cleaner, disconnect the harness and meassure the yellow-black and the white (?) wire. They go through a rubber grommet in the float chamber cover.

I resistance tested the duty solenoid today. I got a value of 41ohms (maybe 41k ohms?). I am not sure how to signal test the 02 sensor, but it looks brand new. I am not sure where to go from here, but the cel has turned off for now.
