When I try to start my 170 all I get is a rattling from the solenoid. I pulled the screen off the motor and see that the starter gear is meshed with the fly wheel. My understanding of starters is that when you engage, the starter gear throws forward into the flywheel. I don't know why the gear is engaged when the starter has no juice to it. When I push on the starter gear, it seems spring loaded and returns to mesh with the flywheel. Any ideas? Also, any easy way to get the starter out? Doesn't seem to be a lot of room.
