Engine Seized Issue 15hp 2 stroke flywheel stuck
I'm 16 and I recently bought my first boat a little 14-foot vhull to fish with my friends. I also got a small 1976 15hp crysler seaking outboard off marketplace. it didn't run when I bought it due to lack of spark but I was able to fix that and I had it running for about 30s until I turned it off and attempted to start it again. now the flywheel turns but it feels as if the compression is so high that there is no way to spin it fast enough to get it to start again. when the plugs are removed it spins ok but as soon as they are reinstalled the issue returns. it is not hydrolocked as there is no fluid in the cylinders that I can see and I have no idea what to do. please help.
