I disagree, Cornelis. There doesn’t have to be a compromise if you can assure that all six butterflies “wake up” simultaneously, as soon as the foot goes on the gas pedal. You can accomplish this by playing with the linkages for hours, but make sure you have a powerful window fan in front of the grill.

Hi John,
I have nothing agains a academic approach, with can make fun.
But even with fresh overhauld carbs you can reset the adjust screws after 100 miles fast driving over and over again.
Well thats my expierance.
Nevertheless the engine runs fine. but the vacuum is not on all openings the same.
Your " playing for hours" I spend on the road.

succes

Cornelis, it may sound a little masochistic, but I love screwing around with these cars. Why else would I do something like this, right? Truthfully, I get a little depressed when a long time goes by and nothing breaks. john

Too bad you don't live near me John. I think my car could break enough to keep you in heaven. And while you were fixing it I could drive one of your cars and, as I've proven, putting miles in these cars is the best way to have to do something about something in your garage.

I have been enjoying all the carburetor talk, but it seems time to let everybody know that I did a five part series of Tech Tips for the Ferrari Market Letter in 1982 and 1983 that covers all of this. It is all laid out there. It covers three and six carbs, DCL, DCZ, DCF, DCS, DFI, DCN, etc. It was also published in my FML Tech Tips Volume 1.

Carburetor adjustment - Part 1 V7#16 7 Aug 82
Carburetor adjustment - Part 2 V7#17 21 Aug 82
Carburetor adjustment - Part 3 V7#18 4 Sep 82
Adjusting DFI carburetors V7#24, 27 Nov 82
Adjusting DCN carburetors V8#3, 12 Feb 83

BTW, Part three concludes with:
For a copy of the complete, three part, twelve step, technical tip on carburetor adjustment, send a SASE to Ferrari Market Letter, 850 Maxey Hill Court, Stone Mountain, GA 30083-2399.

I doubt that the offer is still good, further, that is an old address. But if enough people are interested, perhaps they might make up a set of just those articles at a reasonable price.

Back issues (or photo-copies) are available from the FML. From the FML website:
Are you looking to complete your Ferrari Market Letter collection with back issues? Chances are, we have them! Email Chad Ensz at ferrarimarketletter@gmail.com for issue availability and pricing information.

In looking through my back issues to find these articles, I found several others that I want to go back and read. I've never been able to buy a copy of the FML Tech Tips book. If the FML updated and republished it, I would be first in line to buy it.

Dyke - Do you own these articles or does the FML? I would be happy to help you reproduce them, as long as you get fairly compensated and we don't step on the FML's toes. Also, through the GTE Register and Newsletter, I have the mailing lists and PayPal setup to handle simple sales. PM me is you want some help. I have the FML's and the book, if that makes things easier.

Tom: I do not know exactly "who owns" the articles, as Gerald and I were good friends and we worked together on many things over the years. I personally have no problem with you copying the articles and getting them out to those that could benefit from the information. The times have changed to where this forum is one of the few places that owners of the older Ferraris still work on the cars themselves. Forty years ago, there was so little knowledge that we all had to band together and share what each of us could learn, hence the Tech Tips.

Thanks Dyke. You are a real gent. When it comes to the old Maranello cars, it's all about fiddling with them. Driving them is fun too, of course, but it's not just the driving, because if it were, there are plenty of cars that offer driving pleasure for a fraction of the cost.

Hi John,

You're really at an advantage if you like fiddling with your cars because paying someone to do it can get very expensive. When Francois and I test and tune a car, we try our best to get it to run right as quickly as we can understanding that most of our customers would freak from the time it sometimes takes to get a car PERFECT! The same goes for everything else on these cars from fitting trim pieces to getting the paint just right. We try our best to get things right, often not charging for the real amount if time it takes to get it right so we're happy with the results. Only a minority of people understand how many hours it takes to get things perfect, the rest can live with "pretty good!"

Hi Tom, you said it so well, I don't think I could have summarized it any better. It's about the difference between GOOD and PERFECT. It's not that Sicard or Ottis cannot do as good a job as me, but the difference is that their time is worth money and mine isn't. We were asking Dyke sometime earlier about valve lash setting and how much out of roundness was acceptable. Well, the pro will check to see if the roller is healthy and he’ll set the clearance. Someone like me will take out the rocker saddle put it on dial indicator jig to measure every quadrant of the roller, then will set the clearance on an average of the four quadrants. Now at the end of the day, will all this extra work make any difference to a boulevard cruiser, of course not. But did it offer me immeasurable amusement, you bet your socks it did.
