I always advise conversion to a manual choke. You will always know when the choke is on or off, and you can control the choke operation. I converted all of the 3 squares I have owned to manual chokes. I never had a choke work properly consistently, whether it was hot air, electric, or divorced, and whether I was in sub freezing climates or the hot desert. This conversion will be the best $12 you have ever spent.
