Is there a best site to find keihin carb parts.? Air screw adjuster on the air intake side of the carb. Seized in there. |

Everything in the carb kit below should fit your carb (the pilot jet is 4mm shorter, but will still fit): http://www.ebay.com/itm/73-74-HONDA-CR2 ... 0883003512 Many of the other jets etc. can be found here: https://jetsrus.com/a_jets_by_carbureto ... ection.htm Re stuck air screws, I've had fairly good luck using a small flat punch to repair screw slot damage, then heating the aluminum around the screw with a propane torch (small flame, 30 seconds or less per attempt). The aluminum expands faster than the brass, breaking the corrosion bond. PB Blaster can help too, especially when sprayed on while the metal's still warm. Ray |

Thanks for the comments on heating. I'm out of the garage for a few days so I'm letting it soak that long. Then il try the heat. I have one of those cheap pencil propane torches. Perfect for that kind of work. The air screw is the biggest issue everything else looks very good. Il look at the links! |

If the eBay link doesn't open, go to eBay and enter 400883003512 in the search line, which should bring you to the carb-kit auction. You can also search for kh-0138, which will bring up the same carb kit from other sellers. Ray |
