This is a Tecumseh Snow blower. The carb was gummed up from storage . This is the non adjustable carb. I can only adjust the low speed idle. Machine would not start at all. Took off the carb, cleaned the bowl, cleaned out the jet. The SB would start up and idle without issues. When its revved up (rabbit mode) it would die. Took the cab off again and took it to a shop and had them ultrasonic clean the carb. Carb looks like new now. Everything moves smoothly. Reinstalled carb again. Snow blow starts super easy, idles much smoother. I increase the throttle and after 2 seconds the snow blower dies almost as if its running out of fuel. Maybe I will replace the fuel line tomorrow.
