Pre-takeoff checklist
It happened twice now. On long cross country trips after refueling stop ( about 5-10 minutes ) I start to crank. Props spin enthusiastically and when I feel like it is about to start props stop spinning. I thought props hit some thing so got out and saw nothing. I rotated propellers through each cylinders and no problem. Got back on the seat and cranked again started without any trouble. Engine is IO 540 K1G5D Mag checks are good. Engine runs smooth . Starter was replaced about year ago with sky-tec. Battery seems to be good. Any idea whats going on?
