Hello,I'm fixing an old Eska 5hp motor, I do not know built year but model# 1195. I guess its been made around 60'~70's. My issue is that how to remove flywheel? I need to replace contacts or coil something kind a electrical part to get spark but this flywheel doesn't come out. I removed a center nut on flywheel and applied three leg puller but it didn't move a bit. Did I miss any bolt ?or need special tool to remove it? Other problem is removal lower unit also. There are only two bolt and nut on lower unit .When I pulled the LU after removed the bolt and nut ,It only loses 1/4 inch apart and then it pulled back. Someone can help me to disassemble this little motor? thanks .Noah
