Yes, VW heads have no gaskets, just copper spacers as needed to get compression right. The exhaust flanges should have some sort of gasket that hangs on between the studs; connectors at pipe intermediate flanges should have a fiber "donut".

Bump your idle speed up a little, too. It should be 850-900 rpm.
On the idle I just set where it idles smooth. I will bump it up
I did not replace the gaskets so that is probably the issue.
I will let you know.

Does copper spacers belong between the case and the jugs. OR between the head and jugs

Any spacers would go between the head and the jugs if you needed them. They would only be used to get the right CR and displacement equal between all the cylinders. As for the mixture screw.. I'm not real familiar with Solex units, so do a search for a parts list and view for your model carb. If it's sitting under it's own cap where you have to do two steps to access it, it's probably something that was meant to be left at a "factory" setting.

I checked the other carb and idle air mixture was tighten down so I did the same with that. It helped even it out.

I had a combination of exhaust leak and vacuum leak(from the gauge) . I put gaskets in it helped, but I still have some poping out of the left bank still


I started it with out the linkage and realized the linkage was set wrong. SO I got it set right.
Started it again and it died again and again finally realized I ran out of gas

Good things, I found a vacuum leak found exhaust leaks, got the linkage set but ...........
BAd thing, I still have the* pop but its not consistant. Yes , It still pops a little when it revs.

Tomorrow I will put some fuel in and adjust the idle for the last time( I hope).
Its hard to do though with that motor because it has a light cam in it . I don't think I will ever get it idle perfectly.

Since I have woke up sleeping beauty she has ran for about 35 to 40 mintues.

It does seem the more run time she has the better she is running.

But I still think I need to pull that head again relap the valves put new valve springs in readjust the valves check gap on the plugs again and try it again.

On mine with the solexes it will pop a little on accelleration until it's totally 100% warmed up. No choke on mine so I think it's a little lean until warmed up.

How long does it take to warm up. ran it almost 15 minutes still pops.
Are there any other advice you can give me on these solexes these are the 40/44mm no choke.
Even though I rebuilt both carbs, I think the one on the left is still running leaner than the other one.
I am considering switching the carbs to see if the poping problem switches sides.

Hi guys pulled the head, now I think I better drain the oil.
Why you ask?


Well I'll tell ya.

Cylinders where totally black and slimy. I think the carb is dumping raw fuel in the intake.
When I had the head off 3-4 weeks ago it was clean and shiny. Took a rag and wiped some of the carbon off.

Now that it is off again I am going to dunk it in the clean tank and lap the valves. I am also going to replace the valve springs as well they are only $2.00 a piece.

I let you know if I find gas in the oil.

Dale
The valve on the left I wiped off with a rag no cleaner added.

Hmm... could be gas or just could be excess oil from ring blow-by. The only thing I see wrong in that photo is the plugs aren't the right size - they should be flush with the head.
