What temp does the manifold heat flap open at?

Checked it this morning. Mid 30s outside. After starting and at idle, the flap was *slightly* open. I revved her up using the throttle cable and the flap opened up the whole way. Let off throttle, the flap closed some to the slightly open state. Results could be repeated.

Unless someone thinks otherwise, I believe it is working exactly like the manually states.

I think I need to play with the choke adjustment some more. It's a third party electric choke. Feel free to school me on that adjustment.

Thanks again
