Tat that is what I think it was. Now that I know the heater kicks out the GFI, it has ran good when plugged into a non GFI outlet. I will probably change out the heater this summer. Ran it for 3 hours in teens ran great. Idles a little high I though, compared to this summer. Not sure if linkage is stuck or some type of automatic choke.
What is the rpm it idles at. When you adjust the throttle how low will it go?
