Can someone please explain to me the choke adjustments on the '85 2150A carb?
I made slots in the shear torque screws so I could move the choke thermostat and now the choke will shut completely when it is cold and I adjusted the vacuum choke pull off with the correct sized drill bit and it starts very well now when cold.
If it idles for a while, it will begin to stumble and little and sometimes stall.
I understand that when the thermostat moves the choke open enough the screw will catch in the notch and prevent it from shutting until the accelerator is depressed when the engine is cold again to close the choke fully.
I guess my question is, what is the purpose and what adjustment am I supposed to make to the number 5 in the image below? I read the carb rebuild instructions, but I'm not sure exactly what it is telling me to do.
@RonD I'm guessing you know.
