|A simple rig to unbolt a Keihin non-CV carb on an IH engine without removing anything else. \\ A 3/8" ratchet handle with a 4" extension, spring universal joint (it's spring loaded to allow precise work in tight areas ((http://www.toolplanet.com/product/1-2-Drive-Spring-Universal-Joint/Socket-Set-Non-Impact-Socket)) and a 1/2" deep well socket. \\ It will slide straight in to the top carb stud nut and the bottom one as well (if you hold the horn to one side, it flexes on its rubber mounts.

| This Bendix carb below didn’t have studs, but rather mounted with bolts from the back. \\ |
The bolts were replaced with socket head cap screws for easier access and a custom Allen wrench was bent for the top one.

| ==== General Cleaning and Stuck Gaskets ==== |
| **Carb Stand**: \\ |
Removing the carb from the bike should be straight forward. First thing when it is out is to check the pilot screw setting. ((IronMick of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/47937-cleaning-a-carb?t=185361)) \\ |
| Turn it all the way in until gently seated counting the number of 1/4 turns; then write this number down; then reset it. \\ |
| You can put it in a vice to remove the screws, and for much of the following work. \\ |
|
|
| However, this setup works better than putting the carb (pre-CV) directly into the vice. \\ |

| **Lemon Juice Bath**: \\ |
Pure lemon juice works great as carb cleaner. You can get bottles of it at your supermarket. \\ Pour enough in a foil loaf pan (or an old pot ((Monte03 of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/107811-clean-soaking-carb-with/page4?t=983964&page=4)) ) to cover carb then bring to boil. ((chopfather of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/frame-mount-evo-sportster-talk-1986-2003-models/125690-won-t-idle?t=1265948)) \\ |
| Once it's boiling, put carb in for 5 minutes (1/2 hour or less), remove and spray it with WD-40 to prevent rust on steel parts. \\ |
You can actually let the carb boil at a low heat for about 1/2-1 hour and then an old toothbrush will help with the tough varnish (if any left). ((Monte03 of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/107811-clean-soaking-carb-with/page2?t=983964&page=2)) \\ |
| Bring the juice to a boil, back off the heat and simmer the carb body for an hour. It will smell like all hell, be forewarned. \\ |
|
|
| The acid of the juice plus the heat removes all the gremlins. Then you can pour the nasty remains down the drain and wash down the carb parts with water. \\ |

| ==== Jets ==== |
| **Change jets without taking the carb out of the bike**. A Philips bit works for a Keihin butterfly (non CV) carb. It gets around the problem of not being able to get a screwdriver and your hand around it in between the float bowl screws and the top of the cam gear case. |
|
* With the air filter off, you can take the float bowl off using a ratchet bit driver (available at most auto parts stores) and a phillips screwdriver bit. ((Hopper of the XLFORUM httphttps://www.xlforum.net/forumsforum/showthread.phpsportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/ironhead-sportster-motorcycle-talk-1957-1985/63858-special-tools/page5?t=395586&page=5)) |
| * Works good for getting those jets out too, with a straight blade screwdriver tip. Make sure it is wide enough straight bit to straddle across the hole in the middle of the main jet. |
| * You can also use stubby screw driver, the type with a removable handle. You can take the handle off and use a small wrench on the hexagon where the handle is supposed to fit on the shaft to turn it in a tight spot. |
|
| | Gunsmith screwdrivers work really well on carb jets because they are cut square. They fit the slots really well.||| |
