Greetings:

Proud papa here, wanting to share our white '67 Duetto with the spider forum. This afternoon she was rolled out of the barn, given a few laps up and down the driveway, and placed into the garage. Only glitch was that the clutch had hung up over the long hibernation. A dozen short burst of the starter while in gear snapped it free. Hope to have it registered and aligned, then run her up to the CT chapter breakfast this coming Sunday.

I have put up a short photo album of the restoration for those interested.

Very, very well done. The red interior looks awesome. Congratulations. Please join the Alfa Romeo Spider Register by Wille R.
Thanks for the kind words. Most of the kudos for the seats goes to World Upholstery, who supplied the kits. Most helpful were their carpet & leather samples. The door cards were rebuilt with new boards, but the coverings are original with SEM vinyl paint.

Michael,

The Duetto looks great! I look forward to seeing it Sunday morning.

Greetings: Progress update here. Momentous occasion. I drove her 30 miles round trip to the DMV today. handles pretty well, especially considering I have not had an alignment done yet. The 1750 has been starting right up and is running strong. I did keep to the side roads and avoided the parkway to keep the speed (and recovery risk) down.

Only concern is that the clutch is slipping a bit more than appropriate. Can I hope that that will heal itself after a few hundred miles?

What is the history of the clutch? Newly replaced? Unknown age?

Few things heal themselves. One of your earlier posts mentioned that the clutch disk had stuck to the flywheel/PP, and that you had to break it loose. This happens due to rust, and I suppose it's possible that residual rust has lowered the coefficient of friction between the disk and the metal parts. If so, regular use may abrade off the rust, and restore the grip.

But, if the clutch is old, then no, it won't heal itself. Check that the hydraulics are allowing it to fully engage - the throw-out fork should have some play when the pedal is at rest. Beyond that, you may just need a new disk.

I found my 38 year-old clutch was slipping badly after a similar layoff when I pulled out in front of a fast moving 18 wheeler to pass a slow-moving minivan on the motorway. Nice double clutch downshift, and nice high revving, but no acceleration until I backed off on the throttle and it started to catch. Then I got the 18 wheelers air horns. Embarrassing. On only surface roads up until then. It only got worse and worse over the next day until I thought it might not make it back to the shop. Got a new one, TO bearing, etc.

Greetings Alfajoy:

As you noted, we did need to pop loose the clutch face. The engine/transmission may well have been sitting for 10 years prior to my purchase of the car. I now nothing of the history of the drive train, save that the original 1600 had been replaced with a 1750 by the first owner sometime in the mid 70's.

The rebuild of the 1750 was limited to having the carbs rebuilt and re-jetted by AlfaSport. I replaced the generator with an alternator, and added the EFI we won at the 2007 Convention. So it is quite likely that the clutch is shot. It has the original mechanical clutch linkage, and I have fiddled with that to insure it was not the issue.

The 1750 is not long for life in the Duetto, as I have the OMG's 1600 to swap in along the way. So that process will be the next move. I will rebuild the clutch prior to dropping the 1750 into the '71 GTV that is my next project.

In the meantime, I hope to get a little joy out of the Duetto. When the engine comes out, she goes back into restoration and gets an external media blast and repaint. With the economy as it is, that may be a while yet.

Great looking Duetto; I love the red interior!
Greetings All:

I spoke with the first owner shortly after buying the car in May of 2007. He told me that it was his intention to get a white/black combination. Surprise! It showed up as white/Red, and it quickly grew on him. So it was easy for me to respect the original colors.

I am very pleased with the seat kits from World Upholstery. Nice supple leather, which is a departure from purity of the original, but I'm fine with that.

Oh, this is a mechanical clutch car! So, if the 1600 --> 1750 conversion was done by bolting the 1600 flywheel to the 1750 crank, then the car still has the small clutch. That thing is sized OK for a 1300 - 1600, but is stressed pretty hard by a 1750. So between its age, and the torque it has been handling, I'm not surprised that your disk has given up the ghost.

Media blast? Gee your paint looks OK in the pictures. If you are going to strip it, you will need to disassemble EVERYTHING. Not that I'm arguing against it, but media blasting implies a 100.0% restoration. Another strategy would be to just replace the clutch disk, and have fun with it as-is.

I too like the white/red combination. But, if you want my opinion, the red steering wheel cover is a bit "hot dog" - I'd stick with the stock black plastic rim, or if that is cracked, a black cover..

What he said - on both counts. After a layoff and mechanical rehab, I got the same advice. Paint was a 20 footer (OK from 20 feet). But I don't worry about rock chips, sap drips, and bugs. The 30 year old paint has a certain "patina" as they say in the antique business. . . .

Car looks nice. I was just going to post a request for an engine compartment wiring photo so I can get mine back together correctly. Your photo was perfect. Thanks!!

Ah, good point. I had not considered that the clutch plate inside that 1600 bellhousing would be smaller than optimal. Does that mean that the flywheel is also too small? That raises an issue for me with dropping that set into the 1750 GTV. Guess I'd need to rethink all of that.

Disassembling everything in a duetto is a simple matter, actually. The trim will all come off easily. That step would indeed move it to a total restoration state. Almost all of it has been removed at some point over the last 18 months. American Dry Stripping is an excellent shop in Milford, CT to intrust the blasting job to.

As for the wheel, loosen up a bit! Just be happy I didn't SEM-coat the rear boot cover! I've seen 2600 spiders like that, and they are gorgeous!

Greetings Anfanuts: Sadly, the 20 footer rule is a bit strained here. After getting the car last spring, I did a quick once-over to seal up the scratches and dings. There were several different areas of repaint - three coats in most places, so the original patina is long gone.

But I do appreciate the support in simply enjoying her as she is. That has been my plan all along, doing the repaint out a few years. Just with the clutch slipping.... Ah, heck, what's the big deal about yanking out the transmission and replacing the clutch. Needs to be done regardless...

Greetings intune:

Thanks for the kind words. Be aware that there has been some updating in the engine bay. The voltage regulator was removed, and the electronic ignition module is in it's place.
