To tell you the truth I gave up and kept the HS4 that was on it. It's my wife's Mini and it runs well enough with the HS4. I think the problem was, that I was using a Mini Sport intake that came on the Stage 1 kit that I bought when her Mini originally had a 998. The intake in the kit was supposed to accept an HS4 or HIF44 carburetor but I think the angle of the manifold was incorrect and there just wasn't enough room for the carb, spacer and K&N filter. Since then I gave the carburetor to one of my friends who was having problems with his SPI system in his Mini, so he removed the SPI set-up, got a Mini Spares manifold and bolted my carburetor right up including the K&N filter. He's thrilled with the way his Mini now runs with the carburetor and claims it's smoother with bettter acceleration. His Mini is RHD while my wife's Mini is a German spec LHD.

I'm a little confused, Last year I installed a MG metro 1275 with metro intake and HIF 44 in a 62 850 mini. I recently installed a 1275 Cooper S with metro manifold and HIF 44 in an 85 1000 E. On each I used the 1/2 inch spacer and heat shield as supplied std. On each I used Rover mounts and the latest dog bone bushes. The 850 got a maniflow header LCB and the 85 got a SPI cast exhaust. Both cars were LHD and while close there is no indication anything is going to rub. Can you post some pictures?

Removing the adjustable dog bone from my MK1 was more trouble than it was woth so I ordered a new one. Now I have to wait a week or so until it arrives and try to solve the mounting problem.

To Be Continued.......

This is what I used.

It's a roof flashin turned upside down & I put an aluminum piece over the hole.

Hope that helps.

Fitting an HIF44 would tend to indicate a 1275 engine, as it is too much carb for a 998.
The 1275 engine is 3/8" or so taller than a 998, so you have less height clearance issues at the bulkhead.

At the time of the engine being moved forward by the factory, there were no 1275 Minis in production, they were all 998s.
I tend to only have small-bore motors on my own cars.

Mini Spares manifolds do not come into the "problem" category.

The moke and the mk1 have mini spares manifolds with a 3/8 spacer and have no issues with the bulkhead or the header....

Put a Metro manifold and HIF44 on 2 MkI bodies without major problems. All I had to do was thin the spacer by about a 1/2 to the point where the throttle linkage bracket just cleared the manifold. Its a tight fit in behind and takes some fiddling to get the carb over the mounting studs. Maybe remote transmission motors cant the motor forward a little more.

I have an adjustable dog bone on my 63 Austin. I'm going to borrow it and intall it on the 89 to see if that'll give the proper angle for the HIF to fit. Thank y'all for the input.

On all Minis fitted with an HIF carb as standard, the engine was moved fowards by about an inch - the story of it being done to accomodate the injection gear is a serendipetous myth, it was done to allow fitment of the HIF carb which bangs the bulkhead on a standard manifold.
I fitted an HIF38 to Tubbs on a Metro manifold, and had to whack seven bell out of the speedo hole as well as leaving out the spacer.

With some (of the cheaper) manifolds, the centre branch is of a size & shape that is incompatible with a single carb.
Some of the (cheaper) inlet manifolds have a very flat angle-of-dangle, and simply do NOT fit.

replace your motormounts....i learned the hard way after banging the hell off the bulk head with a hammer and 2x4....lol

The next thing to consider is if the change to a 1 3/4" will be truly beneficial.  If someone has one of the big Vizard books, can they look up the chart that compares how much power/torque a 1 1/2" SU can feed vs a 1 3/4" SU?  I'm thinking that for the state of tune of the rest of the engine, the smaller carb might be a better idea.

I boxed out my firewall for clearance....

HIF44 on Mini Spares big bore intake barely fits and required careful sizing of a custom spacer (thickness of the billet aluminum) and slight relieving of the intake for the throttle cable to run free.

The original 998 had a Mini Sport stage 1 kit and the intake is for a 1 1/2" or 1 3/4" carburetors.

What inlet manifold are you using ?

There are quite a few on the market that are utter crap, with the wrong angle of dangle leading to the carb fouling the exhaust manifold, the bulkhead, or both...

Use a 1275 steady bar, it is about 1 inch longer as I was told they moved the 1275's forward in the sub frame on the 90's Mini's and used a longer engine steady.

There are a bunch of manifolds, and they all have different places where the inlet starts.  erhaps we should have another massive inlet manifold thread dedicated to chronicling the differences.

1989 Mini w/ Metro 1275

When I rebuilt and installed engine I put it back together with the point distributor and HS4 carburetor that were on the original 998. Once I got it running and broke in I replaced the point distibutor with the Metro electronic distributor. OK everything great. So today while Mrs. Mad Dog is in the kitchen cooking up the Turkey I decided to replace the carburetor with the Metro's HIF44 and I find that it doesn't fit. Now I know some of y'all have HIF44 carbs on your Mini's. What did y'all have to do to get it to fit? I thought maybe the spacers is too thick but any thinner and the carb would be resting on the center branch of the headers, never mind the abuntment. Do you have to remove the studs on the manifold and go with bolts instead? I also have a line that goes from the clutch master cylinder to the slave cylinder in the way also (it's a LHD) but I can re-route it if neede be. Anyone have any words of wisdom to share?

By the way Happy Thanksgiving to y'all.
