Weber upgrade on its way

I have ordered a weber 36 tLP for my 1.5.
The supplier assures me it comes with all the bits necessary to fit.
I will keep my progress updated here and comment on the improvement (if any)
The Peirburg is getting annoying, the car runs ok but is difficult to start from cold and unbelievably slow for a 1.5 (although I do a lot of running around in a 2.0i sierra which is quite fast, probably making unfair comparisons)

Ok it arrived, ordered from the Carburettor Hospital, WITS-END, ULVERSTON ROAD, ASHINGDON, ROCHFORD, ESSEX. SS4 3JT.

Nearly ?300 all in with vat and delivery, ouch!
Still it's nice and shiny and new.

Removing Old Pierburg Carb.




Old carb sat next to new carb, they are very similar looking apart from the absence of the auto choke on the 36TLP.


New Weber in place, it just bolted on, gasket supplied, just had to cut the end of the throttle cable off as it is now clamped in place.


Choke fitted inside the car in the recess originally designed for it, had forgotten about that, very neat.




Air box replaced, just had to use a big screw to hold it down as the original clamp would not fit to the new carburettor.

Didn't need half the fittings that the carb came with.

Road test. With a little petrol poured down the carb it fired up straight away. It wouldn't run off choke though when it was warm and the idle fluctuated everywhere. Took off the airbox and tweaked a screw on top of the carb, don't know what it does but it cured it.
Next road test, all fine, had to pull over and adjust the idle speed a few times, one scary thing, I floored it and the pedal stayed down!!!!!
Now as it's only a 1.5 Golf that's not too bad but had to reach down and pull it up, it had felt a bit sticky.
next day in daylight I saw that the clutch cable was touching the throttle linkage, once cable tied out of the way it was fine.
it's off to be set up properly for emissions next week.

Carby Carb Carb...

Hi mate,

That's been really helpful - I've been documenting my GX carb problems here on the forum, and owing to a recent bonus with work and an understanding wife, it's going into the local mkl1 specialist for a full service and new carb on thursday.

I was swithering over whether it was worth spending that much on an old car, but given the car has cost me next to nothing for the last 4 years, and given that it's still in sound condition throughout, I figured what the hell.

Of course it's not just the carb that's getting done, but the fuel tank aswell. Oh, and there's a horrible scraping sound coming from the front nearside, which might be nasty.

I'm budgeting for around ?600 to get it all serviced, but hopefully it won't come to that.

Cheers,
AndyC

1 week on

Well have only used it a couple of times and still need it setting up properly for emissions by the local garage but it runs quite well. It's still a bit difficult to start from cold but I think I've not got used to the choke yet and flooded it again. The difference now is that I can wait 30 sec and try again with no choke and it usually starts. With the old carb there was no chance of starting it unless you took off the airbox and held the flap open.
The car runs a little smoother when warm but to be fair to the pierburg it was the original carb and hadn't been overhauled EVER.
Part throttle it's a bit nippier but overall performance is the same as it is only a single barrel carb. You'd probably need an adaptor or different manifold to fit a 32/34. Anybody got one on a 1.5?
Not sure of any economy difference yet, need to actually go somewhere in it, have been cycling in all the nice sunshine instead of driving.

Response to Andy C, it is quite  a bit to spend on an old car but if you're planning on keeping it and it costs you little anyway then why not. I find the maintainence costs are the same for a small car as they are for a large one. My carb with VAT and delivery actually came to nearly ?300 so you will have to pay if you want somebody else to fit it.#
Nasty scraping noises are often CV joints or wheel bearings which aren't that hard to fix. Let's keep the old motors going, it's a better environmental choice than throwing them away and buying some overcomplex new thing with only a 10 year life expectancy due to it's unecessary electronics and evil aircon.

Delighted!

Afternoon…

Well, the car's been into the garage and they couldn't find anything wrong with the carb, or autochoke. In fact, they said it was in remarkably good condition given the type and the age of it.

It transpires that the previous garage (look at my other posts for a history of this problem) didn't set it up properly.

Total cost to me, ?40 +VAT.

Just waiting on the report on the front wheel - I suspect it's the bearing, but I'll wait and see. After that, itr's a full service and back on the road.

Then it's off to the body shop for a bit of cosmetic surgery- watch this space!

Cheers,

As above, get the car on axle stands and shake the wheel to test the bearings.

Good god, turning a screw you dont know? Are you mad? No offence, but if you dont know anything about carbs then leave them alone! Let someone who knows what they are doing tune it up. You need the correct fuel to air ratio, and for that you need all the computer equipment to measure the emissions. You get that mixture wrong and there is serious internal enginedamage on the cards, especially if running lean.

Well have been away for a bit so not using the car.
Had the emissions set up by the garage. It's still quite difficult to start from cold, too little or much choke and it won't go then it floods and you've to wait a minute.
When driving it does feel zippier, there's more grunt, only a few percent but noticably livelier. It was always poor at acceleration above 50 mph but gunned it on the dual carriadgeway last night and it pulled quite hard. Have not yet measured fuel economy.

Just need to perfect the cold starting routine, usually I can start anything.
