Replaced primer bulb and cleaned carb with aerosol spray, replaced fuel tank (old one was cracked), Put in fresh gas/oil mix but still would not start. I bought a new spark plug and then it ran. Adjusted carb and it now works great. Including the carb kit I have $32 invested and it runs like a new machine again and starts easily.

I started by removing the air filter cover and box. That gave access to carb, so I took off the carb, and removed the broken bulb. I then put on the new bulb and reassembled in reverse order.
