How is your Hall-sensor installed? Both washers usually have to be on the topside to make the gap small as possible.

Just came out of field flying MVVS 58, Xoar 24x10, MTW RE2 pipe and DIY MTW header kit in EF Extra 88". Could not be happier how the motor is working. It's still under break-in, but I have had zero deadsticks, automatic choke is working fine and vibration is minimal. Few liters more and I can switch to 2% fuel.
