1986 Toyota Pickup 4x4 mileage: 150,000. I cannot get this truck through smog. The readings are great at Idle, but at 2500 rpm there is 2% CO 30 ppm HC 1% O2 and 13. 5% CO2. I know this is a rich running condition. I have changed the 02 sensor, and nothing. Before I replace the carburetor, I wanted to ask you guys. Thanks

Do you
have the same problem?

Your carburetor may be the problem, but if you have the original catalytic converter on your truck, you might want to replace that first.
