Matthew: what kind of 'wing nut" are you referrring to - the standard female bolt type?

If I remember correctly, I used 'GY' needles.

Spank, aparently it was for the LHD brake master cylinder, and is essential if you use the large late-model master.  I had one when I used the carbs, then I sold them and bought them back.  Sadly though, the tatty box had been replaced with a round-sided box which was painted in a dark blue metalic.

Check out this thread - more than you'd ever want to know about twin HS2 air filter boxes.

EDIT:  I checked my old purchasing records and discovered that I'd bought a pair of 'M' and 'E3' needles at the same time as when I'd bought the K&N filters and small-bore LCB. 

So, I probably ended up using the 'M' needles as I can't find them amongst my tubes of carb needles.  Had I been using them, they would have been fitted to the carbs when I sold them off.  I've bought the carbs back, but it's anybody's guess as to what is sitting in the carbs right now.   Hope this helps -

(I had a pair on my 850, might reinstall them on the 998 at some point, but I first need to find a MKII-style air filter box - the one with the flat-angled LH side to clear the brake master cylinder.)

Ah...I have one here sitting in primer ( sorry to tease....not for sale right now..lol )....but, I think the wedge in the latter ones was for the relocated washer bottle.....no(?)  I need one "wing" nut for it btw if anyone has.

 Hijack, hijack, Hijack

Jeg, when you used the carbs on an 850, what needles did you use?

Please continue.

I'm actually surprised that our host doesn't appear to stock this seemingly necessary component.  Of course, if one were so inclined, one could make one from a section of flat washer, possibly around 2 cm long x  1 cm wide(just a guess, mine is fitted to the carbs and I might have extra one fixed to a trunion in a bag of assorted grimy carb bits)  by drilling 2 holes, 1 large enough for the trunion and 1 small for the spring. 

Yes! Going as far as to provide a link to the part needed (would have taken me quite a while with Google-fu) is seriously much appreciated.

Looks like I forgot a small component, namely the anchor for the spring.  See item #27 in the attached image - it's a small tag that hangs from the trunion pin.  Basically, the pin passes through the tag, then the triangular butterfly linkage (12A310), then the cable on the other side.  The spring fixes to the dangling tag.

I've forgotten how many washers are involved, but on mine, there's a whole slew of them. 

By the way, be careful of the UNC screw that fixes the throttle cable bracket to the intake manifold.  The newer manifolds require that the screw be shortened as not to bottom out and/or puncture the manifold.

If you're missing one, MSC has them.

Thanks Jeg.

I knew I was missing the bracket, but did not know about the choke connector.

My point of frustration is I can never find a clear diagram as to how all of these connect to one another. Logic would suggest the throttle trunnion should go through the center linkage, but that hole has a spring on it (unless the extra hole on the throttle trunnion is for the spring???). Then the question is what does the choke trunnion connect to? Arg.....classic Mini workshop manuals are completely useless

You'll like the HS2's - they look great, give good fuel economy and plenty of grunt for the mildly tuned engine.  (I had a pair on my 850, might reinstall them on the 998 at some point, but I first need to find a MKII-style air filter box - the one with the flat-angled LH side to clear the brake master cylinder.)

To connect the throttle and choke cables, you'll need these if your existing linkage doesn't have them:

ACC5062K_Throttle-Cable-Trunnion-Pin-Kit

AEG349_Bracket-Throttle-Cable-Hs2-Dual

AUC5046_Choke-Cable-Trunnion-Connector

Attached is an image of the AEG349 bracket which has the ferrule for the throttle cable.  This screws onto the intake manifold and is clearly depicted in Spitz' attached image.

Alternatively, if there's any wear in the linkage kit you've got, now's the time to get everything in one kit.  It'll save some hassle when you balance them.

Just a quick reply (in case anyone cares!)

Decided to go the dual HS2 route....even though it's a moderate hot rod I still think it's cool to have the original dual carbs on the car. Just got these back and am looking forward to the install, once I can figure out how the throttle cable attaches to the dual set-up.

Car is slowly coming along; hope to have fuel lines in by mid July and get the engine fired

Well unfortunately, no.

[edit] this was back in 1970 or 71.
I slowed down from 100MPH+ for a village (35MPH) and then realised there was a Cooper S on my hammer, he pulled me over! He said had got up to 106MPH downhill during the chase and he estimated I was doing 110 (Fiat 124 Sports Coupe). But he was so far behind I didn't know he was there.

The highways back then had a 55MPH `/' prima facie speed limit. If you drove at say 90mph or more and a highway cop was displeased, you were not charged with speeding, but with `driving at a speed dangerous to the public'.
It was hard for them to prove unless you hit something, swerved or did other silly stuff. Basically you had to prove in court that you were driving `safely'. 50% of people who fought it got off.
So, I did too. But it cost me some $$$.

Not long after, the highways in NSW were all speedzoned to 100KMH. Easier for the cops to prove their case.

Spitz, I'm guessing it was set up for a block-mounted mechanical fuel pump which would explain why it was "backwards."

Mehoff, I'd vote for the dual HS2s as well. Weber 45? Waste of time and money on a street car. Some boy racer would be happy to buy it from you. Nothing wrong with the HIF44 suggestion depending upon how many parts you'd need to get the HS2s set up vs. what you'd need to buy and install an HIF44. Other than the HS2s would have been the original carb set up if that is important to you.

If he chased you for 20 miles Kevin i assume you got away ;-)

The NSW Police Dept used Cooper S for highway patrol duties in Australia, back in the late 60s and early 70s.
But they were mostly factory modified, with a ported head, twin HS4s, Ramflo sports filters and C-AEA731 cam. They were good for 106mph downhill (as I found out when one chased me for 20 miles in 1970).

Lol....yes...put that way as that's the way the fuel line comes up  ( maybe not on an S )

Just to add to what my friend esmith said.... the HS4's really need a modified engine, larger valves, larger bore, more compression, more cam... Most feel that they do offer an advantage for higher speeds or open road use with the increased CFM, but like most things, there's a price to pay for that last little bit of performance at the top end....

Most are indeed much happier with the single HIF44 for all around drivability.  The weber does have fans, but is almost always a compromise in a street Mini, you must enjoy the smell of gasoline!

This short video has me explaining the compromise of fitting a DCOE on a Mini:

Yes, fuel line assembled backwards.

Either way will work but i think Matt's is on the wrong way unless the fuel line comes up the opposite side on Canadian Mini's :-)

This is the fuel line that came with a few sets I've had
