365 GT 2 + 2 restoration

Postby A.D. » Fri Feb 09, 2007 2:14 pm

I have recently become the proud owner of a 365 GT 2 + 2
S No 12171.

The car smokes, runs fuel rich, and lacks power.I have been on Ferrarichat and have recd some invaluable advice from some of you who post there.

I called out a carb rebuild kit from Pierce manifolds to attempt rebuilding the weber 40 DFI carbs.However the kit seems to be far too inadequate for attempting a serious rebuild.I am therefore (instead) now thinking of pulling the carbs and sending them to Mike Pierce at Pierce Manifolds for rebuilding.

My question is-have any of you had an experience with Pierce manifolds and is this the correct approach-of letting an expert do the rebuild rather than attempting to rebuild them myself? Is there anyone else other than Pierce manifolds that you would recommend?

Welcome to my site!

There is not much to a rebuild kit, but there are a few things that tend to go wrong with an old Weber. The throttle shafts wear out, and ovalize (is that a word?) the body of the carb. This wear makes air pass past the throttle plates, and causes tuning issues. The carb bases also warp from age and over tightening, causing more air leaks. The needle valves at the bottom of the floats also leak, and sometimes stick open. This causes the carbs to overflow, and a potential fire hazard.

I have not done business with Pierce Manifold in years, but I had a good experience with them. If they rebuild your carbs, you can at least start with properly operating carbs. There are a bunch of variables involved with tuning the carbs once you get them back, but I'm sure we can walk you through the process.

No, "ovalize" is actually something that happens to that former high school prom date you haven't seen in 20 years.

Hi A.D.

Some of the security measures on this forum don't allow you to take too long to compose a post. If you get that horrible message about a message failure, hit the back button, copy the text, and paste it to a new message.

Sorry about that, but it keeps spammers from taking over this board.

Thank you for your reply to my post.

For those of you who are interested this is the story of my car:

My neighbour bought it brand new in 1968.A bright yellow GT 365 GT 2 + 2
S.No. 12171.

I was five years old at the time, when it roared into my life and thus began my love for classic muscle cars, fast and powerful.

Somewhere in my twenties i tried to satiate this yearning by buying and abusing a couple of camaros, mustangs, a cuda, a 500 sl etc, most of which i still have today.

But the music of twelve cylinders coming to life every morning at 6.45 a.m. drove me crazy until i did acquire the car from my neighbour (37 years later), alongwith a 1972 porsche 911.

I have more or less known the history of the ferrari ever since it drove in next door in 1968.

When i bought the car the engine had not been started for several years and was therefore jammed.After a lot of patient labour-pouring oil through and turning the engine by hand (which process took a few months) changing oil filters, cleaning plugs, fuel tank, fuel line, rear brake pads, cleaning and freeing up the brake calipers, removing and cleaning the radiator etc, i finally had the courage to fire the engine.

The smoke that the car gave out initially was incredible! But after running the engine for a few days the smoke gradually reduced although it still does smoke quite a bit.The car lacks power, smells terribly fuel rich, and after a very short while the plugs get fouled.That is why i am focussing on the carb at the present moment.

The engine sounds very healthy and i feel that a good tune up-rebuild of carbs,new spark plugs and wires, i feel that we should make significant progress.

After reading your post, i now have the confidence to send the carbs to Pierce for a rebuild-as you stated, that way at least i will start out with the carbs done well.

Once they are back , with your help and support i will put them back on the car and also change the wires(have acquired 7 mm red colour spark plug wires and the correct plugs).I have also purchased a synchronometer n adapter from Pierce for synchronising the carbs once they are back.

Is there anything else that you recommend i acquire while waiting for the carbs to come back in preperation for a full tune up-rotor?(rutlands has it) points (dont know what/where to buy)air filters(dont know what where to buy)-distributor cap(dont know what/where to buy from)

my question:should i buy all/any of these? anything else that i havent thought of?

if so any information where to get them from would be greatly appreceated

Now that You'd ran the motor few times, have You performed compression check and "leak-down" tests ? If not, I'll think You should
do those before going any further, especially if the motor was not running for several years, it could have "stuck" rings, etc...

I Agree with Timo. Do a compression/leak down test on the engine. If the motor was siezed, there could be some damage to the cylinder walls that would cause low compression. Some of your smoking could be from this. What did the plugs look like after they fouled? Was there a lot of oil residue? Perhaps with some more running, the rings could seat and seal a little better, but having compression numbers will establish a baseline. I've heard of some success using some of the "miracle" additives, but I wouldn't add any until we figure out the root of the problem.

What condition are the ignition parts? With any other car, it would be cheap to replace these parts, but with a Ferrari...the points can be filed, and if the cap and rotor look good, I would try to reuse them for now.

There should be someone here that can tell you what air filter to get for your 365, but if you have a good autoparts store around you, I'd try to find a match there.

I'm sure you've bought the usual books for your Vintage Ferrari to help you tune it. The Tuning Tips and Techniques and the Riff book are good places to start.

You have a great story beind this car. Good luck, and I'm sure I speak for the rest of us when I say we look forward to helping you get this old girl back on the road!

A.D.,

did You drained ALL the old gasoline out, not only from the tanks, but also from the entire fuel system or did You just added "fresh" gas into
the tanks ? If didn't drained it ALL and flushed/cleaned Your entire fuel system, You should also do it NOW and replace the gas ONLY with "fresh" fuel, before going any further. And while Your at it, clean/replace all the fuel filters and flexible fuel hoses also. This of course becomes an secondery issue, if Your compression/leak-down tests aren't giving satisfactory readings. So, do Yourself a favor and perform those tests first.

This might also be a good time to flush the cooling system, especially since the car has been sitting for a while. Make sure you flush the heater core as well. Check that both electric fans are working too. I would also consider replacing the radiator cap with a new one.

My brother has a 365 2+2 as well. Great cars.

Good luck,
