Hey everyone,
Finally purchasing a Weber carb for my 1.8 Golf GL this week as I have had nothing but issues with the Pierburg 2E for the last few months.. I've had issues where the revs have gone a bit mad and are stuck at around 3k, making sat in traffic not much fun. Then the massive over run when you kill the engine which just sounds awful.. Pretty sure this is related to the waxstat and fast idle speed, but i'm sure a new carb will help solve many of these issues.
I'm pretty excited for the build as i'm buying a Weber brand new, but I have a few questions..
1) Whilst the old carb is off, is it worth be changing the 'Channel O Ring' (Think that's what it's called..) - I have a new one ready to be fitted, so is it worth doing that before fitting the Weber?
2) How easy is it to fit the manual choke that comes with the Weber kit? I've tried to find some info on this online but failed. Is there an easy way through, any photos of where is should sit inside the car?
3) I'm not a huge fan of how much space the original air intake set up takes up. Would it be worth while fitting a bolt on air filter such as K&N or RAMAIR to bolt on to the carb? Would this more likely cause carb icing? Also, where would the connections/pipes go that are currently set up in the original air flow system?
Thanks for all your help,
Stefan

Look to left of stearing wheel theres a cap on the dash. I put my manual choke in there. I also chose a gromit thats close to go through. Youll have to look and see as I camt remember off top of my head.
I kept standard air filter. My mates got a knn on his. I donr know where pipework is though
Fit it if its there. Meams its a problem that shouldnt occur later on
-
Thanks for the reply, very helpful!
The Weber arrived last night and I started fitting it straight away. Not as difficult to fit as I first thought, however the one piece I need to take off the Pierburg is the 'Heater Element', but the original is almost on it's way out.
Can you buy these anywhere online? Or is it best going to a scrap yard?
I'll take a look at fitting the manual chock this evening, hopefully it's not too hard to fit!
Also, I'll be sticking with the original ait intake system, but may invest in a K&N filter to fit the original system :)
Thanks!
-
You could try gsf or tps. Or eBay.
One should have it. Glad I could help
-
What does the 'Heater Element' do exactly? Would I still be okay testing the new Weber even if the heater element isn't attached?
Thanks
-
Aids cold starting I believe. So in this type of weather shouldnt be a problem
-
Thanks for that!
Just installed the carb, but I'm unsure what to do with a pipe which leads out of inlet manifold? It used to go into the right hand side of the Pierburg, a coolant pipe I think, any idea where it should go now?
Thanks,

All sorted now :)
I believe everything is fitted correctly, my only concerns are the electrical connections I have left over.
Obviously there's the 'Heater Element' which has recently snapped so isn't currently connected, but now I have a few other lose connections.

Im also not hearing the starter motor click when I turn the key in the ignition.. Quite odd..
Thanks
-
Photos arnt working. So cant tell you whats what.
Is it running?
-
Hmmmmm, that's annoying..
It's not running no. Everything looks to be connected how it should, apart from the few lose electrical connections.
I'm not getting anything at all when I try to start up.
I've had jump leads on the car in case the battery was flat, but the lights, CD player and everything else is working.
Starter motor was fine before, surely it can't be an issue now?
Thanks

Doeant one go onto the brake fluid cap? Not sure on the other 2. Sorry bud. Havnt got a carb engine anymore to check. I can get my mate to chexk his outthough
-
There's already one connected on to the brake fluid cap, the rest used to go on the old Pierburg carb so I'm guess they were for the automatic choke..
The single red connector in the second photo has to go somewhere surely?
Still not able to get it firing up :/
Thanks
-
Ill get my mate to look ob his
-
Hes only got 1 wire stray.
If you go on a2 services there good ce1 and ce2 diagrams to see where things go.
That wire cant be far from its plug though
-
Got everything going!
Sadly we've come across some backfiring in the carb when you put your foot down.. Trying to find the right mix, but it's still popping.
Any idea?
-
Might need to adjust ign timing a touch. Sounds like its sparking while inlet valve is still open slightly
-
Yeah we've been having quite a battle with the idle mixture, idle apeed and distributor timing, but we've still got some carb popping.. We've also started getting over run when the ignition is turned off.. Used to have that on the Pierburg which is odd..
We're so close to having it finally set up!
I do have a small hole in my exhaust, but that shouldn't make the carb backfire right?
-
Exhaust shouldnt.
Over run is carbon build up in the bores. A qood fuel additive or something thats ment to decoke the bores will solve that.
Knock the mixture screw off and then tuen 1/4 turn at a time until ir starts. If ign timings bob on shoupdnt be too far away then.
When your doing ign timing are you pulling the vac pipe off so it doesnt advance
-
Okay cool. I always use 'Redex' and actually have a full bottle in the boot so I'll throw that in next time I fill up.
We managed to sort the backfiring out, but when we took it out for a drive there was a real lack of power. It was really struggling when you put your foot down, like really bad, so we turned to the ignition leads/plugs.
We had a dead lead and 1 plug wasn't sparking all that great, but by the end of a long very hot day, we managed to get the car on the road, and what a beautiful noise the new Weber makes!
We're still having issues with a slight lack of power when you put your foot down, it kinda chuggers a little until you reach high rpm which by then you can't really notice it. Had to be a timing issue.
Tomorrow we get the timing gun out to check it and hopefully see about getting a decent set of plugs/leads!
Thanks,
-
have you checked your cam timing? the camshaft might be retarded by one tooth.
-
We now seem to have the timing pretty much spot on which is a huge improvement to the ride! Got her idling nicely and the Weber is performing really well!
We now have a major oil lake however haha
It's coming from the fuel pump where it sits in the engine, as we also fitted a new fuel pump at the weekend. The rubber seal is broken, but there's no replacement part out there to buy brand new? I've bought some high temperature gasket material which I'll use to cut out a new gasket which should sort out the issue (Fingers crossed!). I expected the new pump to come with a rubber mount, but it didn't, however there was a new o ring but it's not behaving!
I was also able to weld up the hole in the exhaust, so overall a productive weekend!

Failing gasket paper. Use high temp sealent. Glads its starting to come together
