First problem is you probably should figure out which engine you have. The Toro was never offered with a Chevy 305, nor was the TH325 trans ever made with a Chevy bellhousing. Either someone did a custom swap with an adapter or (more likely) you really have an Olds 307 (VIN Y).
Assuming this is the case, be sure you have the correct carb. Next, get a factory service manual. The electronic Qjet is extremely sensitive to proper functioning and setup of the carb and all the emissions equipment. A minor problem with a seemingly unrelated system (A.I.R. air injection, for example) can fake the computer into running the carb full rich. You MUST follow the troubleshooting and adjustment process in the FSM exactly. Do not expect to simply bolt on a new carb and go. The good news is that once the system is set up properly, it runs very well.
