Battery is 1 year old, 55Ah and it had this problem since it was new... in an ideal situation I would try another battery when I get my hands on it.

I peeled back the insulation on the blue wire and the wires are great, I noticed when the wire is unplugged and ignition on it has 12v, as soon as I plug it onto the alternator it only has 1 volt?

Took off the blue wire, rigged up another wire on that terminal and touched the battery 12v wire that goes on the alternator and it works, guess there is a short in the blue wire since the car also started pretty rough until the car started charging, doesn't happen if I don't hook up the blue wire. Going to run a separate new switched 12v to the alternator and problem solved then.

So I am having this problem for a while now on my 1990 Favorit, when I start up the car the battery light stays on and the battery is not charging (approx 12v at the battery), as soon as I rev the engine up above like 3000rpm the light goes off and the battery starts charging (14v). I have just replaced the alternator with a new one and the problem is the same, any ideas? Grounds look fine.

Looked at the intake pipe and turns out something broke inside of it so the flap was always sucking in exhaust air so I just permanently set it to closed, seems to help a lot. Still a bit rich I feel because I can smell it.

Winter mode?

Thanks for the info, I just find it weird because this never happened on my old Favorit and it was a really beat up and neglected one. I do feel like it is running a bit rich - black condensation from the exhaust and sometimes when I want to accelerate from a stop theres no response from the gas, kicks in like a second later.

So my Fav has been running good for a while now, drives good but I'm having a problem where it wont start hot, need to crank it for a bit and hold the throttle open for a few seconds and then it slowly starts up. I have replaced my carb base gasket again, got my hands on a metal plate one because the rubber ones just seem too sketchy to me. Also replaced the idle cutoff valve. If I drive it around and shut it off, it doesnt want to start up. Fires up cold no problem. Any ideas?

One more question - car runs perfectly, checked the alternator charging voltage and its about 12,7v at the battery, is that normal for these cars? Its a brand new battery. The battery light also comes on when the car starts but after a quick rev of the engine it goes away, my old Fav also had that but never any issues.

None of the people that work here have knowledge in carbs and old Skodas anymore, mostly younger mechanics. These cars have been pretty much off the road for the past 20 years here. Luckily we have the internet and a lot of documentation, found a good PDF of Pierburg 2E3 diagnostic which helped a lot, diagrams helped me figure out where fuel should be coming in.

IT WORKS! I was absolutely sure I had done everything right up to this point so there was just one thing left... clean the carb and rebuild it. My distributor position was indeed wrong so thanks for that tip. i took it all apart, brought it to work (conveniently I work at VAG/Skoda) and I cleaned the carb ultrasonically with a tool to clean fuel injectors. A ton of dirt came out and most importantly unclogged the main jet which was fully shut with dirt. Got myself a Pierburg 2e3 rebuild kit and put new membranes and gaskets on... ofcourse came up on an issue along the way, idle cutoff valve gasket fell apart totally and I did what the old time VW mechanics did... double oring and teflon tape. Put it back together, used some extra sealant on the crappy base gasket, waited some time to cure, tighten down again... STARTED UP FIRST CRANK LIKE IT NEVER EVEN STOPPED. Learned a lot from this, now I can easily say I can make a Favorit run, learned distributor timing, valve clearance adjusting, carb rebuilding etc. Now it just needs a few bits and its back on the road. Thanks for any help. And PS... I bought THE LAST carb body gasket directly from Skoda so theres no more of that except aftermarket.

I removed the idle jet, idle cutoff valve, cleaned it all out and no effect. I haven't messed with carb settings it ran perfect before the engine was removed.

If I take the line off the carb and crank the car fuel squirts out... fuel clearly gets into the carb even when I took it apart the float bowl was full of fuel, there must be an issue with sucking the fuel inside but I have no idea what to look for from there on. I removed the filter that is in the inlet on the carb too and it was clean. If I press the throttle I can clearly see fuel squirting in through the top jet and it also runs if I keep pressing the pedal, just doesnt add fuel on its own.

Had someone crank and I kept spraying brakeclean in there and it kept running no problem.

Here it is, the wires on the second pic are black - white - bare - yellow and a ground on the housing nut. The spark plug leads are in one of my previous posts, I put them on just like your pictures.
