Replaced carb on tiller 5 HP Honda engine. Was back firing and low power.
Found a couple of videos to look at before doing the repair. Took my time. Removed fuel tank. Drained fuel tank. Removed air box and filter. Removed Carb. Linkage was a bit tricky but it turned out well. Hoses removed fairly easy. Also replaced fuel filter and air filter. All went back together well. Also put in new spark plug and changed oil. Fresh gas and ready to go. A few pulls to get started as the carb was dry. Runs great. Just be careful not to bend linkage or stretch springs.

The air cleaner cover was broke and missing, letting rain water into the engine
1. Removed fuel tank
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!

Dead Carburetor on Old Tiller
The carburetor on my 10+ year old tiller finally stopped working correctly. I took the old one off and put the new one on. It wasn't as hard as I'd envisioned. I had my husband check my work when he came home as I'd never done this before. It took a few pulls and my old tiller works great. Actually, it hasn't run that smoothly in a good many years.

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.
