2. Removed old air cleaner assembly and carburetor
3. Replaced carb, gaskets, and air cleaner assembly
note- if you replace the carb you will need to get x2 on some of the gaskets
4. Put fuel tank back on.
The motor runs good now, parts fit well, the only tricky part is keeping everything lined up when putting it back together. I drained the oil out of the engine and set it on its side with the carb up so I could ''stack'' the parts up as i put them on. Thanks for the prompt shipping!

Even for a total newbie like me there really aren't any special instructions. I just took everything off that I needed to while noting their position and how they were in there in the first place. Then replaced the parts and put it back together. The nice thing is that the only socket I needed was a 10mm. There were two short screws and two very long bolts holding it on and that's all. Really not a bad repair. I think my time is higher because it was my first ever engine repair. It would probably take a person who knows what they are doing far less time.
