Hello Kevin,

I don't follow your argument, a HS 4 is a HS 4, why buy another when the small items that are required are cheaper than a second hand carburettor?

Because I can do him a good deal on one of my spare singles ;)

I'm still undecided about getting a good front carb for the 2000 before I flog it, so depending on the waxstatness I might even be tempted to do a swap...

Well Alec you suggested
you should be able to identify suitable throttle levers, float chamber mounting adapter etc. The float chamber will bolt either side but you will need a new adapter.
Well I cant see these parts from Burlen are going to be cheaper than a £10 - £15 mini or metro carb (have you looked at the prices of their parts ) and all the messing around involved thats needed as suggested by others.
My reply is not an argument just simple economics.

Right.
Problems and solutions:

The floatbowl:
This will turn so it sits vertical. Only needs to turn about 5 degrees, there's enough give in the fuel pipe to acheive this.

The linkage:
Choke is the same.
Accelerator - its easy to modify the HS2 link to fit. The center fits the spindle fine. Only issue is you have to hammer flat the choke cable 'arm' and fit it on-top of the linkage already there - which acts as a spacer to clear some other pokey-out bits. Works fine!

The needle:
Still unsure about this.

The reason it's not fitted and going?
I don't have a manifold spacer! Was going to bung it on over the weekend, simple job thinks I. Until I had a sobering thought - "Aaargh I've got no spacer!"

Assuming I don't get a carb from 'packedup' I can buy a spacer that has a vacuum take-off already fitted. So, this solves the vac advance problem too!
What would Macgyver do..?

I get the feeling my spare spacer is sat on someone's Mini engine right now (along with my spare HIF44 and spare 65d dizzy...), or I'd chuck it in with the carb :(

Pretty sure I know where my Dolly 1300 HS4 is, not so sure I haven't nabbed bits off it over the years though... Will have a hunt either tomorrow or Wednesday and see if I find a complete one :)
