1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

Another angle, these are from earlier today. I guess it would be broke. Looked ok to me but the only one I had that was obviously broken fell out when I took the flywheel off.

Not a problem at all

When you fit your new woodruff/flywheel key make sure you use a little bit of grease on the dome side to help with friction whist fitting the flywheel back on or its an absolute nightmare to fit

I'm sure its not he needs to send a picture of the flywheel in place located to the key to see if it makes contact

I do too. It doesn’t appear to be broken to me. If it is I’ll swap it at a later time. I don’t know what to do to fix my motor from here.

Pitting at the top of the crank and is this top part of this a part of the key look at the picture of your flywheel you have a misshapen sharp point
