1500 44 PS VW beetle 1967

[Beetle1966]

G’day,

I have just finished restoring my 1500 44PS 1967 beetle (matching numbers, H-Motor). At this moment, I am having trouble with the engine running as it should. Number 1 and 2 are staying cool while number 3 and 4 are running at a normal temperature. When idling and running up to 1300 rpm, the engine runs quite okay. After that, I had the impression that the engine sounded very limpy or dragy. The compression is okay (all four of them are between 8 and 8.5). I still have to check if there is no air leak on the single port side (No.1 and No.2).
I would really appreciate any advice. Thank you in advance.

Benno

I'm not really helping, but that's a '67.

Nice looking car. My brother had a Euro '67 (1500, 6V, covered headlights, front discs, etc), and we all loved that car.

If one side is running hotter or cooler, I'd check for any obstruction in the fan housing, loose flaps/rods with the thermostat mechanisms, check if all tins are in place, then check for air leaks at the manifold causing lean/hot running, and even exhaust and heat exchanger leaks or other failures. Then dig a little deeper and check valve adjustments and plug color.

When did this problem first show itself? Was it uneven before the restoration, or is it new? What all was done on the motor?

yes, check for an intake air leak on that side, a squirt of carb cleaner or propane should find the leak if present. take a look at all 4 spark plugs, see if one side looks different. also ohm out the spark wires, and cap.

also recheck valve clearances.

oh and double check the spark wires are not going to the wrong plug, done that before!


good luck


ps very nice looking car, you done good

G’day,
Guess what I have found when I took the inlet manifold off? I found double sealing washers on both sides. The upper copper ones for no.1 and no.2 did not seal properly. Half of the copper ring wasn’t squashed properly as it should’ve been. This lead to an unwanted amount of air, getting sucked in. I took the old ones out, assembled the lot, started the motor and “Bingo”, the motor ran like a “Beauty”, as he should.
Thank you all for the big help.

It's so cool when someone posts an issue like this and how quickly it got solved with just a few posts from the experts.

Well done!

You have a beautifully done Beetle, Benno. Now that the engine runs well, go out and drive it alot!

Page 4 of the registration document shows "Jahr 1966"- this could've been the source of confusion. Here in the USA we go by the model year (1967), compared to much of Europe's "date of first registration".

G’day,
I had another good day in the garage. The motor is still running well, but I had to adjust the valve clearance. I also checked the pressure on all 4 pots and I was happy with the kilometres the car has done (close to 97000 km). Next step will be cleaning the car, which is really necessary. The rubbers still need to go on the rims. Then the car will be ready for some more photos.

Zenith Blue 67s rock!

nice job painting the rims, it will look a lot better!

Should be disc brakes off the similar vintage Ghia. That's why it has 4-lug wheels, unlike the USA (drum) models with 5-lugs.

Here is something off-topic for a moment:
There’s something that just crossed my mind. A long time ago (1986), my family and I visited L.A.. At that time, we booked a room at the HEIDI Motel. There we met Chucks from Chucks’ convertible. After all those years, I lost contact with this fantastic man. After arriving in L.A., he even took us out for lunch. The attached photo shows him on the right hand side, the other one is, guess who, me.
I wonder if anyone knows Chuck. I would really appreciate anyone’s help in finding him.

Have you been to his website?

I need someone’s advice on how to get the 6 Volt horn working properly. In default mode (engine off, ignition on, 5.5V messured on the horn), it just gurgles. When the engine is running, the horn works fine. Is there anything I can do to improve that?
