Gearbox, solved. Oil level was too low. It took about 750ml to top up. It's leaking some around the axle tube paper gaskets, but I think the issue was that some of the oil got into the tubes. Does it say in any manual to top up after first ride? I will keep it under supervision until I build the other one.
And I installed the front sway bar. Half an hour job using screw type clamps. I expected the ends would be located under the lower arms, it sits somehow below and on the side. When it's lowered on wheels, it fits better. Let's see how it sits now on the asphalt.

No problem, it happens. Actually you got me thinking about the main difference between IRS and Swing. Just came to my mind that some oil from gearbox does flow into the axle tubes, maybe the oil level in the gearbox gets too low? There was no spot under the car, but even more important to check oil level.

Thank you for the ideas!
Gearbox oil, check. I replaced it completely. But I will check the level.
Mounts are new, but I will inspect.
I did not check anything on axles, not even disassebled them. Just new gaskets for setting tubes play/force. Grease for what?
I highly suspect mainshaft bearings... And I will swap the trans anyway. I will do the rebuild on the "new" one. I just hope the on on the car will last some more so my wife can enjoy the car till winter.

That transmission noise could be mainshaft bearings or the differential carrier bearings. But check the three mounts first! Those can cause noises too!

Gear oil is good and full?

Axles are in good shape? Grease is good?

If everything checks out okay, you will need to disassemble the transmission and look for the problem.

Fingers crossed for it being low oil!

Long weekend fun. We attended a bug and bus show in Hungary, Gyomaendrod, 200km away. We go there every year from Thursdays to Sundays. Lots of cars, spa, pools, kids games, raffle, and the most funny tradition, the parade and water battle. Everyone in the village is out with water guns, buckets, hoses etc and from the cars, who is brave enough to drive with the windows down, can fight back in the same way. Busses (especially single cabs and dokas) are most suitable for sprinkling back, having the "stage" behind . I will post some movie clips once available.
We even got a prize, I guess for beauty.

I received the clamps for front stabilizer bar, so now to install it.
I also picked up the '67 transmission I bought some time ago. It's short (4.375), so I will replace the R&P to 3.875. I intend to do the swap during winter, but I might have o do it earlier. There is a growling noise during deceleration, and I read it may be one of the bearings in the gearbox. MAybe some hints, what it could be? It is not present during acceleration, coasting, or when clutch is depressed.
And I need to address that acceleration cable, it keeps sticking and throttle plate does not close enough.

Weekend work. I bough some more carpet and glued it to the rear seat back. Looks good.

I tried again to install the front sway bar. I made a 19mm drill and enlarged the holes in stock rubber bushings. Well, no success, the bushings become too thin and get pinched when trying to tighten the clamps. I tried again with the provided urethan bushings. Again, no go, they are too hard and can not get the clamp so close to install the retaining clip. I think the clamps with screw would work, but they were not provided in the sway bar kit... Now waiting for a set. Also, the sway bar touches the lower arm, maybe I did not get it in the right position or is it something else?

Nice work, it's good to see you and family enjoying the car and traveling in it-good luck bob

[tzepesh]

Yup, it is! Kids too.
This week we finally received the TMI seat covers, ordered since November. Man, do they make a difference!

It's great that you and your wife are enjoying the air-cooleds together.

600km round trip this weekend, to a meeting called BusStock and American Shine. Overall, a very nice event, family time, good weather. Many campervans, not only VW, more bugs than american cars . It was up on a montain, ~1400m altitude, with 100m altitude difference in ~20km, so pretty steep. It ran without any technical problems, but my wife drove pretty slow as she was getting used to the car (quite different experience to my 1303). Three issues: one whitewall came off and broke, so in the end I will remove all of them. The wheels do have a thin white bans, so it will compensate. Front wheels are rubbing the fender edges, the dropped spindles have some offset... I will try to pull a bit on the fenders. Last, we had very strong winds and my wife struggled to keep it straight at high speeds. At 60km/h it was ok, more than that and the wind would push her. Alignment was properly done before leaving.

Yeah, well, remember the shifter issue? Look at this pics and tell me what is wrong...

I was just reviewing in my head how I assembled it, and why the reverse does not lock and it struck me. I was always looking at the plate orientation, and never at the position related to the spacer. Yes, it had to be under it. Changed places and yes, it shifts perfect now.
Today I took her out for a ride, to help another friend turn on his bus, 20km away. Drove at the incredible speed of 95km/h. Damn, this gearbox ia short! I need to get and prepare rhe other one with some proper gearing (read that 3.88 R&P).
And I need to address the accelerator cable, because it does not allow the throttle to close back completely.

I bought a 67 transmission only because I wanted the long drive shafts. The wheels look funny so deep under fenders. Now, to see when I can pick it up, because it is 400kms away. Anyway I will not change anything till end of the year, to give some time to my wife to have fun with the car. Already she was complaining it "yells at her" at higher speeds (read that 70km/h ). So hopefully it is a medium ratio gearbox, otherwise I will just buy a 3.88 R&P and swap it. I avoided for years to work on gearboxes, but I have enough parts to make the fork alignment jig out of another case, and to somehow make the pinion nut tool. I'm only afraid of the pinion and ring setting.

Another issue I have is the shifter, especially first gear. I also installed a quick shifter, because my wife is not so tall. But I can not get it to shift well no matter how much I tried to adjust the plate position. I checked 3 times that the plate has the correct orientation. Also, it gets to reverse whithout pushing down. It was working better without quick shift, at least the reverse. I found this thread to explain the best.

I repaired a bit a carburetor from a friend (bushed the throttle plate shaft, choke lever), and installed it. It responds to the tuning of both screws, mixture is ~4 turs out, air 1.5 turns in, steady idle at 900rpm. So I will have to get a better 34PICT 3 and rebuild for my own.
I received the metal tubes for sunroof cables and installed them. Sunroof works smooth, until I install the headliner part. That moves very hard all by itself, and makes the sunroof work very hard. Any ideas here: I checked the upholstery not to be overlapped, so to have thicker areas. I need to pull it off again. Also waiting for the metal reinforcement plate.
Yesterday we participated in an oldtimer cars event, "Photo finish". We drove around town and then parked in the city center in front of some musums, as it was also "night of the museums". We caught some rain, too. A few pics now, more will come.

Fid the bugs! Hint: we formed a semaphore. The yellow one is a good friends, who helped me a lot and for whom we worked the whole week up till late in the night to get running.

Then, many artsy pics:

Another big step, we got it registered, so all legal now . And we took it for a ride, runs pretty well. I would shorten a bit the brake pump rod. I adjusted it longer, to have at least 20 cm from splash panel, but the pedal position is not "natural". And it affects the clutch pedal in the same way. And to work some more on the carb. It starts, it runs, it does not die, but idle is too high and irregular.

Great project. Your W90 has a bit more duration than stock. You may want to up your idle RPMs a bit. Mine has behaved similarly but produces great torque on a small motor. Cheers

The carburetor setting gives me headaches. I tried the method described here
http://www.vw-resource.com/34pict3.html
I can not get it to idle using the air bypass screw. It runs on choke, but once the throttle plate closes, it will die. I suspected the "fast idle" screw being improperly set, so I tried to feel when the carb barely creates vacuum for the dizzy. Well, it the fast idle screw was set properly.
Check several times for air leaks, with starting fluid, and watching afr. Only when I spray it at the filter intske I can see a sudden change, no leaks.
Still, it does not react to air bypass adjustment. Only when I screw out the mixtrure screw for about 6 turns will it idle, and will run the same even with the air bypass fully seated... What on earth?

Yes, valve cover gaskets.
Thanls for the tip. I am also quite reluctant to work on those gravrl guards. Also, others had to cut and weld the fenders, too. This would be also my case, as they are not wide enough. Tested by others on original and repro fenders, fitment was the same... I simply can not understand how Flat4, who are well known for high quality products, can manufacture these so badly. I think they will stay o the shelf for some time.
