i recently rebuilt my e4me ccc-qjet and while placing the airhorn i broke the plunger on the tps, i have replaced the tps but now the car runs rough and wants to stall after its warm enough to open the choke. do i need to adjust the screw under the plug or should the factory setting still be correct since i did not change the airhorn?

You are setting the carb and TPS to each other. So, you need to check the voltage and adjust accordingly.

1. Set timing
2. Set TPS for 0.40 (as close as you can) volts at idle
3. Adjust idle mixture screws and Idle Air Bleed for 50% duty cycle on Mixture Control Solenoid.

Let us know if the TPS adjustment fixes it. May have a little fine tuning to do on the carb rebuild.
