Product Description

?

This is a Genuine Honda replacement part, it is sold individually. Its propose is to deliver an electric current from an ignition system to the combustion chamber of a gas fueled engine. It will ignite the air fuel mixture by the spark. Spark Plugs will usually have to gapped to the manufactures specifications found in the owners manual. Over time a Spark Plug will become fouled because the air/fuel ratio may be set wrong,worn piston rings, carbon build up and other factors. It is better to replace a fouled spark plug, rather then trying to clean it.

Dead Carburetor on Old Tiller

Glory from Winter Garden, Florida

8 of 8 people found this instruction helpful.
Difficulty Level:
A Bit Difficult
Total Repair Time:
30 - 60 mins
Tools:
Socket set
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.

Not too difficult. Requires moderate skill. My suggestion would be to take pics with phone especially of adjustable parts (i.e. idler cable) to aid in returning them to their previous position.
Even though you can use the old thermal relief valve, I would order a new one with the pump order. I also changed the oil and spark plug w hile on the bench. Overall it was an easy repair.

1. I removed the old carburetor (three 10 mm bolts behind the air cleaner element), noting the order of the gaskets, the spacer, the shield plate and the linkage connections.
2. I disconnected the fuel line after moving the spring clip with pliers.
3. I connected the new carburetor to the two linkages and with new gaskets, re using the spacer at the engine block. I also attached the fuel line and moved the spring clip back in place to secure the hose.
3. I tightened the 10 mm bolts that hold the carb in place.
4. I replaced the air cleaner element and then the spark plug (also changed the crankcase oil).
5. Runs great now!

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 change d 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.
