I'm having trouble with my starter. I'm not quite sure what model starter it is, so I'm attaching a few pictures. When attempting to start (for the first time of the day) it feel like it's slipping... It feels like the gears aren't engaging and I can't get the prop to spin. If I let off the ignition and try again it fires right up. Flawlessly. Does anyone have any ideas on what could be causing this? Suggestions on what can be done to fix it? Thanks! Neil
