I have a 3W24 for my PT-26, great engine, never had no problems. This past weekend, I had one flight, the next time I went to start the engine, I jammed my finger in the prop, seems at compression when I usually flp, she flips real smooth, that time the prop stoped as I went to flip the prop, any reason why this happened, still today a few days after this, she still is tight. Any help on how to solve this would be great. Thanks Joe
