a good rebuilder will measure the amount the valve stem protrudes before and after, and grind down the valve top to get the same distance after the lapping/grinding.

didn't even know there were other manufacturers. Went with the Bosch's, think they were like 30 each from monointegrator.com

The seals I would definitely replace. I replaced mine, and to get the injectors out, I typically use a wrench/pliers. If yours are hand tight, airleaks are probable.

Injectors is not a must-do, but ...

#lifehack on the bottom bolt of the wur; take a much longer bolt, thread a nut on It with loctite at approx the same distance/length as the original bolt. Now when it dries, you can put the new longe ...

I printed the rubbers for the swayer. The ones for the ARB's I purchased... they are actually vw rabbit ones, so if you search on the internet you might be able to find cheaper alternatives than the ' ...

looks like a very complete kit. It doesn't contain the intake mesh, but idk about that; never had to remove it.

Not exactly, but I'm quite sure it's shorter than a meter.

The tube for the alternator is pretty standard 50mm heater tube. Bought it on aliexpress for a couple of bucks.

Sounds like you're getting somewhere

the basic mixture can also be tuned by sound. Turn the screw lean (i think ccw) until the idle becomes erratic, then twist until it becomes smooth again and try ...

That seems to point to the WUR or the cold start valve. Given that you already had issues with the WUR, I'd start with that.

I assume you did test the war with power on the heating element?

Agree with all of that raize.
The point I was trying to make is that even tho the design is a bit flawed and was updated later/in other cis systems, a well functioning system should not have issues. ...

Even with the return going directly to the tank the WUR should hold pressure for approx 20 minutes. I have an older car where the WUR bleeds directly to the fuel tank and residual pressure is fine for ...

Yes, these look 10 times better... And they fit without an issue. Upgraded mine too.

But I also think this would affect cold control pressure, because the small post is exerting some force on the diaphragm when cold, its just less force than when the bimetal spring is warm
Yes, when ...

With calibrating the WUR, we mean setting both the cold and warm pressure. The warm pressure has to be set first, by pushing in or out the black fuel cell...

Ah, this is interesting - I've not hear ...
