My moki seized!
I had just started the engine, and was waiting to take off. The engine died and I had to restart it. When I then started to move out on the field it died and I was unable to turn it over.
A few minutes later when I was taking off the spinner it freed up. I disassembled the engine and could find nothing wrong.
I was using 20% FAI fuel. The oil was 1/2 klotz and 1/2 castor. The engine is tightly cowled with its head sticking out the cowl about 1/4 inch. I have had several flights with this aircraft with no troubles.
Any ideas about what caused this?
