Leaf Blowers

I have a 125B handheld blower that is about 8 years old. It has been a great blower up until recently. I was getting vibration and I noticed oil on the bottom. I bought a fan blade, a cruise control leaver,fuel filter,seal kit and a lower bearing cap. I reassembled it with fresh fuel, new spark plug and air filter. It would not start. I used a spark tester and decided to change the coil. I made sure the flywheel key was aligned and the air gap was .010. It would not start, even with ether. I checked the compression to find 65 psi. After disassembly I checked the ring and found it missing a section. The bore looks clean, but I didn't measure it. I also checked the muffler and it is clear of blockage. With a new ring I am getting 100 psi. Still no starting, even with ether. What am I missing? (Fuel+Fire+Compression = Boom)
