4. Slide the bottom cover back, and pulled the gas tank out.
5. Removed the two screws behind the air filter, pulled them out and slid the carburetor up.
6. Hooked the new gas tank line to the new carburetor. Ran the line from the carburetor to the primer. Then ran the primer overflow line back to the gas tank.
7. I slid the carburetor in replaced the two screws, then slid the new gas tank in. Tightened the bottom two screws that were just loosened to hold the gas tank in place. Replaced the top cover put the final three screws back in. Then changed the spark plug. It fired up on the second or third pull and ran better than when I purchased it new.

The choke was not closing tight, making it hard to start.

Now it start on first or second pull every time

Only problem is the studs that secure the carb to the block are a speciality tool that is not available. I had to use pliers to remove the studs.
