The first flight with my home made OBG, Tiger 60 / Super Tiger 90-K, Master Airscrew adj. 3 blade prop, took off and while climbing out the engine went lean and stalled.

While the engine was winding down and out of desperation I pulled back on the throttle and shoved it forward a couple of times and the
engine restarted (big smily at the time) and I flew some laps at part throttle, landed and adjusted the high speed needle.

I flew with much more confidence after that not before realizing that benefit, great insurance.
