Is this adjustment made with engine cold or at operating temp? Thanks a bunch.

The ready start has no controling mechanism while running, the fan should blow the air vane away, opening the choke fully within 3 secconds of starting. The heat coil by the exhaust is only for when you kill it. This keeps the choke from closing fully on a hot motor, which was a big problem with the old Choke-A-Matic carb from the 60s.

Make sure your air-vane isnt binding on the metal arm by the muffler, and oil the air vanes pivot point. I have a ready start system that I set up myself, and I have finally worked out all the bugs, allowing the motor to start reliably and easily every time.

You are right, but the arm needs to be adjusted to make sure that it allows the air vane to open the choke on start up. Set wrong the thermostat arm will not allow the choke to open until it heats up, particularly in cool temperatures.

yes, the left/right adjustment is what you need to adjust to keep it from binding. when its cold you move the air vane from closed to open and adjust the arm so that it doesnt contact the air vane. Foreward/backward adjustment doesn't affect the opening of the choke while running, just warm startup. I have found that a .050 gap between the arm and vane at full cold below 100 degrees is a good setting, it allows the choke to fully close and keeps the choke open the correct amount for a warm engine. You can alter the gap either way to make firing a warm engine easier.
