I removed and cleaned my sison choke. This is the closest thing I have to an arch enemy on this car. Prior to cleaning when the lever arm was connected to the carb the unit would click but not pull the arm down more than a 1/8" if at all. If the arm was disconnected the lever would move fully if activated. I removed the unit cleaned and oiled it and reinstalled it. (it was really dirty and covered in surface rust.) Now the unit will activate the choke 50-60% of the time. It seems to be related to the temp. I have set the unit up according to the manual. This morning for example, 30 degs pressed the peddle fully once and then held at half throttle when I turned the key the choke did not close . it left a ¼” gap and the car would not start. ( I cranking for 15 secs. Then pump the peddle twice, and repeat, it took 8 tries to get it to start ). Yesterday afternoon at 50 deg. it snapped shut every time you touched the key. So could it be that my electromagnet is so week it cannot fully operate the choke? I have run a manual choke in the past, but i want this to work right.....
