best carb for 1098

I'm picking up a 1098+box from which i need the box, the engine has no carb but is (or was?) a runner.
Now, I'm also looking at possible saloon which has 948, so was thinking that if I went for that I could put in the 1098 at some point but that of course requires a carb.
What is recommended for good performance, but simple to set up (no twins etc)
Cheers

Single HIF 38 on MG Metro inlet manifold - works very well for me. I do have a spare HIF 44 which will try later on this year - but really the 38 is big enough for a road going car.

Agreed - For a standard to mild/ moderately tuned road 1098 the HIF is plenty good enough.

Look in "parts for sale", Picky is selling a HIF38...

But it does need an MG Metro (or one of the many copies) inlet manifold.

Not entirely true - It can be fitted to a Mini manifold, which can be fitted to a Minor to retain the opriginal exhaust without messing around. Yes, I know about the heat spot, just saying! It can also be fitted to a Mini inlet that's been chopped off a Mini exhaust, thereby removing the heatspot. Also, the 1275 Metro cast inlet, IIRC according to Vizard, is the same as the alloy one but cast as one piece with the exhaust, so again seperating one of those (or getting the fancy aftermarket downpipe that allows use of the Metro "LCB" manifold) would be an option.
But obviously exhaust issues aside, the MG Metro inlet is by far the easiest way of going about it all

Pheee -ooohh - at last. The ones i bought were only £5 each - but they are ever more popular and so may cost rather more today. Search ebay - or do a deal with Matt.

If you look in Vizard's book then he does say that the Metro inlet achieves its good flow figures through quite large ports, which lowers the port velocity and thus low-end torque. I've got an Oselli Torquemaster inlet for my engine project, which has smaller ports but still reasonably goos flow. Cost £25 from ebay.
The Minor engine bay doesn't have the size restrictions that the Mini/Metro bay has, so you can afford to use a longer inlet manifold.

Rob, changing the carb can cause compatability problems with the intake trumpet and airbox. In my experience it can prove to be a bit of a headache getting the right bits.

OK, but this engine has come without a carb so I'm starting from nothing anyway and just thinking about options.
got it all home and looks OK, gold seal gear box, but have yet to separate them and looks like rain now, so the gear box swap will have to wait.
