    Hey Guys,

    Can anyone recommend a good carburetor rebuilder for my 40DCNF’s on my 79 308GTB in the Southern California area? I’ll remove them myself and bring them in to the shop. I was hoping to get a good recommendation from someone that had a good experience from a well established business.

    Well, I’m going to jump in to it, that’s to say that I’m going to tackle R&R’ing the carburetors. I though I’d take a few pictures before I remove them. Other than that are there any special tools or parts that I’ll need that you could recommend?
    Also any tips would greatly be appreciated.

    Thank you very much,

    Chris.

    I had thought they were Midwest, if not on the East Coast!

    Thanks Guys,

    I'll keep them as an option. What are your thoughts on this: I was considering on removing one at a time as to insure proper replacement (linkage etc.), regrdless of who rebuilds them, I thought that to be a good idea, especially if there was a rebuilder here in So. Ca.

    Thanks, Guys!

    Chris.

    There's nothing magical about rebuilding carbs (if they are assembled correctly now). The most important thing is attention to detail. It's essentially: disassemble carefully arranging the parts as they come out, clean and inspect everything, reassemble exactly as they came apart (with the new parts from the kit), adjust float heights (as described in the WSM), reinstall and reconnect the linkages and fuel lines. Then you will need to synch them and set idle mixture and idle speed.

    Pierce is a good place to take them, they will be right when they're done. I suspect it might be quite expensive that way but if there are problems with the carbs they will know what to do with them.

    Tim,

    I've got a set of Boxer carbs that I'd like to have new throttle shafts installed in. Likely, they'll need to have the housings bushed. Other than Pierce, who would you consider for such a job?

    Are you sure the carb shafts dont run on ball bearings like most other Ferrari's? I cant imagine us 308 guys got the top shelf stuff and the Boxers didnt. If so, you just replace the bearings, keep your shafts and not worry about re-bushing the carb body.

    Chris,

    I had a 308gts carb years ago. I rebuilt many carbs and it is really easy. IIRC the shafts are bushed not bearings btw. I'm in redondo beach area and if you wanted to drive out this way i could rebuild one with you and then you could do the rest. If available buy one of those weber carb books it has all the steps. Buy the rebuild kits and you are good to go. IIRC the only issue that needs special parts if rebushing a leaky shaft. If you had a running car the rebuild should be almost academic. I'm not even sure where you buy the rebuild kits anymore. There use to be a place now gone redlion in redondo beach. I'm not sure if they went somewhere else. There is a guy in riverside/ontario/paris Jim Dalton who is a cagey old ferrari mechanic turned high volume computer guy who may be able to do it for you. He can do the most amazing things with bandaids, chewing gum, a nail and roll of duct tape.

    Paul,

    No bearings are used in the model of carb, nor on it's 3-barrel cousins; the Muira or the Porsche 911. In essence, there's a throttle shaft, a small nylon-looking split sleeve (the bushing) and the carb body. I'm hoping that the wear I feel is just the nylon piece being worn out...and there's no wear in the carb body itself. Fortunately, many years ago, I purchased need throttle shafts for these carbs and do have, on hand, the throttle shaft "bushings".

    Thank you very much for the offer! The car's not currently running, I'll take a look at her this weekend to see if this is something I'm going to what to handle myself.....If I bring my self up to enough courage to do it myself, may I call you? Other than a rebuild kit, might I need anything else to bring the carbs back to O.E. (concourse), condition??
    Thank you very much!

    Chris.
