I guess before I buy a rebuild kit, I need to know what carbs I have. Can anybody positively identify these, or let me know how I go about identifying them?
I have been assuming they are Weber 40's. If that is the case, will this kit work? https://www.cip1.ca/ProductDetails.asp?Prod...de=ACC-C10-5542 Would I need anything else on top of what is supplied in the kit? |

(most likely) |

They're Spanish webers (if you look closely at the carb base says made in Spain). Now, wedge your phone/mirror down on the other side of the carb and in the same location it'll have some letters/numbers stamped in that say 40 IDF 70 or 40 IDF 71 if they're 40s. If they're 44s, it'll say 44, etc.
Only other way to measure is to pull the carbs off, which if you're rebuilding them, you're going to do anyway. Then measure the individual throats at the bottom. |

I've seen it stamped there once before, perhaps I was wrong. If you're rebuilding them, why not go ahead an pull them off and have a closer look? If still no stampings are visible, measure the the diameter of the bottom of the throats.
FYI, most Weber 36, 40 and 44 kits should include all gaskets, regardless of carb size. You order them and select the right top gasket once you get the kit in front of you. |

New to webers? Buy the CB manual. If only for the information.

Another good source is:
http://www.redlineweber.com/ Or my #1 most favorite parts place for non-porsche specific parts: https://www.pegasusautoracing.com/group.asp...upID=WEBERIDFPJ Just DO NOT buy from webercarbsdirect. They are selling chinese knock-offs NOT real webers. When I rebuilt my carbs I used an ultra-sonic parts cleaner from Harbor Freight and cleaned every piece including the carb bodies. You have to flip them a few times (they wont fully submerge, tank not deep enough) but it worked. I even used denatured alcohol in the parts cleaner for the bodies, but I did that outdoors due to the fire risk. The #1 biggest thing to know before diving into a rebuild is that the butterfly plate screws SHOULD be very hard to remove. If you dont back-up the shafts while pushing hard enough to extract the screws you WILL bend the shafts. They are expensive and require additional tooling and drilling to replace, so dont mess them up. And if you DONT bend them, you will save the cash that you need to replace the bearings which SHOULD be done if the carbs are very old. |

Spray clean them on the car to get the right numbers off of them.
Use standard carb cleaner in a well ventilated area. An old toothbrush will also help. Rich |
