Pierburg 2E3 choke

18p each at farnell R30-6200814 but It's not like we need lots so ebay is ok I think.

That's more like it! I'll order some of those in then. I like Farnell - free next day delivery.

I thought you needed a trade account, can anybody just buy?

[CJH]

Yep

Maybe the trade thing is a restriction for planning purposes on the physical stores (I.e. not general retail) but that doesn't apply to mail order.

Forget that - they only have one store I think, in Leeds.

You have to wonder what People like Bromyard do with these broken bits?

[CJH]

Haha, yes, maybe we're tackling a problem that doesn't exist. Maybe there's a ready supply of genuine replacements somewhere.

[itchyfeet]

This bit I think you mean...

Try gower and lee and bromyard vw otherwise you may have to buy a second hand carb and salvage the part as I did.

Well I'd say it's worth dropping them an email, they will either have a solution ( which may be just a supply of scrap carbs) or if not they will be interested in what you are doing I'm sure.

I can agree with that.
BTW I found some ptfe tube for the spacer

Here's a video of the part being printed...

And here it is in situ. It's a bit tight next to the upright for the pushrod socket, but otherwise it seems ok. I'll need to compare the geometry to the original part, and try it mounted in a carb with the corresponding linkages, but it should only need a few little tweaks I think.

[itchyfeet]

wow you don't hang about

I managed to catch my mate and his Ultimaker 2 between jobs. Good job too - some of his prints take 19 hours. This one only took 40 minutes.

[Mocki]

impressive!

can we get the 80-90 logo on them? lol!!

[kevtherev]

Superb work CJ

[CJH]

I checked the geometry against a good unbroken part - it was almost there, just needed a couple of tweaks. So here's what I hope is the final version. Some bits shaved down, some corners rounded off, an obvious blunder corrected (I had divided 9.5 in two and come up with 4.25), and a 0.5mm recess for up to a 10mm washer in the top, just to make sure that the part remains free to turn when the rivet is pulled up tight. I've opened up the centre hole a fraction for the same reason.




PS Wasted a lot of time trying to emboss the logo into the surface....
