I just got a hif44 with manifold from a friend and im thinking of putting it on my 1098. I don't have a problem with my twin hs2's and I like the look of them but I wouldn't mind having a single carb when tuning. I know could put it on and if it doesn't run the way I want I could always go back to the twins but I'd rather not waste the time and a couple intake gaskets. Let me know what you know or think. thanks.

Ok, now you know the results and don't need it how much do you want for it?
haven't decided to sell it yet but you have dibs Phillip. I checked out some of the mini forums and it looks like this is a popular setup for 1275's although some people put them on 998's. i would think its too much carb for a 998 but they're probably not worried about bottom end power. I'd still like to see some comments from someone who has run a hif44 on a small bore engine.

I have a soft spot for morris minors. I learned to drive in my dads morris (red one in my pic). we had 4 different ones growing up, 57 2 door (the red one and the first one we restored), 58 convertible, 58 2 door, and a 59 traveler. big fan of the pop out turn indicators

This is the one I learned to drive in, I'm the one on the left in second picture, sorry they are sideways, don't know how to fix. I dated my now wife of 47 years in a two door.

Regarding single vs twin:
1) once you balance the twins you never need to touch them again (until they are worn, and their throttle shafts need replacing, like 50,000 miles later), so that is a red herring about single carbs being easier to live with
2) the single carb manifold which is widely available is angled "up" for the mini, so the dashpot will crash on the bonnet when closed unless you fit a shortened dashpot (available, but an additional thing to get sorted out when making the conversion)

The HS2 throttle shafts run direct in the bodies and so the replacement of the throttle shafts is usually straight forward.
X2 on synchronizing them. Most carburetor problems are electrical on nature.
Warmly,

I agree with how easy it was to overhaul the SH2's new shaft was tighter fit than the bushings they sent so no need for that hassle. Solid butterflies made it better for down shift and hold back. I just would like a single on the Morris Minor, hood clearance not an issue.

I see someone said to use the "bucket method", the only problem is getting it mounted good and you have to start out with a small hole then work your way up to the point that you are getting the correct amount of gas for a desired speed. Almost forgot, you'll need a shut off valve.

you need a 2 bucket system, the first bucket is mounted flat with 10 holes spaced about 1/4 up the side facing to the rear of the bucket. second bucket is mounted below so it will catch the fuel as it falls out of the first bucket.
as momentum increase the fuel will be forced toward the rear of the bucket and therefore flowing out more holes.
should be fine for most aggressive engines.
