More likely the problem lies with a faulty throttle position sensor (TPS) switch than with carburetor adjustments. Go to your public library and check out a Haynes or Chilton Repair Manual for your vehicle. Chapter 6 will give you procedures on how to retreive the trouble codes to determine for sure if the problem lies with the TPS. You will also read the procedures for checking/replacing the sensor.

I have attached a link for the 91 B2200 vacuum diagram, it should be almost the same. Mazdatrucking.com is a great resource with lots of info on repairs.
Yes, this is as easy a swap as you'll ever do. It's the same engine almost; same cylinder head, same carburetor, same starter, the B2200 uses an F2 which is a slightly modified FE which is what you will find in the last few years B2000, I think 84-87.
