Hi,
Does anyone have knowledge of or a link to a list of Minis which used either HIF44 or HF6 carbs as stock?

TIA

[mab01uk]

Single HIF44 1.75" SU carburettor was fitted to 1275cc Minis and Mini Coopers from 1990-1994 before the later 1275 Minis up to 2000 changed to fuel injection (SPi and MPi).

 

(also used on 1275cc Metros...and some other BL/Rover cars with carbs before fuel injection became standard due to emission laws).

No Mini use the HS6.

Mine uses the HS6 but never as standard fitting. Just in case OP is thinking about using one.

I thought the RSP Cooper was the only carb'ed Cooper, with the later ones (J reg-onwards) being SPi then MPi(?)  I also thought other 1275 Minis (Mayfair maybe Sprite) used HS4 carbs(?)  Does that limit the HIF44 to the reintroduction of the Cooper on the RSP model or are there other special editions, Italian Job etc which may have used them?

I'm going to stick my neck out and say that the Clubman, or at least, some Clubman, had an HS6.

 

But it was a long time ago and although not confused, I will apologise, if wrong.

The SU catalogue says just the cooper had HIF44. All the other 1275s had HS4 or HIF38

I've just found this old thread on essentially the same subject which says Coopers were SPi from October 1991. I think there were only 1,000 RSP Coopers released so if any non-RSP Coopers were released before Oct-'91, they might also be HIF-44.
It appears any other 1275 (i.e. non-Cooper) was on just a HS4 (38mm) carb.

Have I missed any Minis on the HIF44?

No need to apologise, but none did from the factory. The 1800 did, I can't exactly recall but the 1500 E Series may have also in some cars.

The slightly earlier HIF6 wasn’t used from the factory on any minis either (they were 44mm like a HIF44 but had the HS type dashpot).

To strike off at a tangent, this reminds me of when the GPO (General Post Office) Moved on from Morris Minor delivery vans to Morris Mini Minor vans.

 

Under a deal, struck back in the mid 1950s, BMC  agreed to supply the GPO with Minor vans which at the time had the 803cc A30 engine and HS1 carburettor  The GPO were so happy with this combination, that they wished to continue using it when they moved on to the Mini Minor vans, and for a nationwide contract, BMC obliged them with this specification 803 engined Mini vans, for a while.

 

It wasn't long before the vans became the standard, off the line, 848cc Mini Van with an HS2 SU carburettor, but the cost conscious GPO specified that the 803's HS1 plate that held the accelerator cable should be retained.

 

Postman, fed up with this restriction, especially rural ones, could be found parked in a gateway in their lunch break. filing the HS1, 1 1/8th" plate out the to the HS2's 1 1/4tr" diameter orifice.

 

When our Postman explained why he would like to use the Vice in the workshop, I bought him an HS2 plate from Henleys and for over 30 years, had a Christmas card from him.

I can remember being shown the 'strangler' plate on the GPO van's carb to reduce the throat diameter, supposedly for economy. That was at the GPO workshop on Western Avenue in Cardiff in about 1965.

My 1990 Cooper had an HIF44 as standard and it still has it. I have done a bit of work to the carb and manifold to improve flow.

Is that an RSP Cooper or did yours fall in the few months between the reintroduction of the Cooper and the introduction of the SPi model?

Over here, I'm told that PMG (Post Master General) specified low compression ratio engines for all cars/trucks. They allowed only the use of the lowest octane fuel. Minis probably weren't that bad but Kombis are already slow, PMG ones much slower.
