Post subject:  most reliable carburetor to use on the mini?
Hi Guys,

my last car that had a carby was my 1985 RX7. I always dreaded having a carby because it always had issues starting, warming up and guzzled more fuel. Now that i have a mini im afraid to go down that path again.

But having a smaller engine and definitely more reliable than mazdas wankels, i was wondering what your thoughts were on this matter. Does everyone have a preferred carby they use in the mini world?

I know for the Rx7 world if i remember correctly everyone was really into the 48 IDA weber. It was a DOWNDRAFT carby. It is exactly the same carby as they used in the beetle world - with jets etc to suit of course. This carby was the most expensive though. I remember people paying up to $1100 dollars for a brand spanker and $800 for a rebuilt one.

Is there a carby that everyone here would like to use on their mini if money wasnt an option?

Of course ideally there is also the EFI mini engines which came out in 1993. Though these engines are definitely outside my budget.

Any thoughts on the matter is greatly appreciated.

Thanks everyone,
Merc

Why not ask for the cost of an EFI conversion, and see where that leads you, if not, get a pair of SU carbies and fit them, as they are the most popular on minis and everyone seems to know what to do with these to get them running spot on.

You are lucky enough to live in the state where the experts live, you should not have any problems if you fit the SU's.

Good luck, I have EFI and its fantastic, but I needed the reliability.

Rover EFI..reliable until they break..and then its $$$ to fix and a total pain in the ass.

I would go with a 1 3/4 or a webber setup. 2nd hand and get it rebuilt properly.

I like my HIF44, it seems to be set and forget.. actually I never even set it, it's just been left the same way for 6 odd years, since the previous owner took the car off the road... I would like to try a fish carb though, theys sound interesting!

You had best give a little more on what you are after from the engine in terms of performance and economy, idle quality that kind of thing. There's lots of great choices for the mini, and they are usually relatively cheap (god bless their cotton socks).

that just sounds like general rotary behaviour, and bad tuning...

what do you mean "money wasn't an option" - do you mean "what is the cheapest and most reliable mini carb"

I'd have to say a single 1 1/2" SU, or maybe a 1 3/4", but an SU, and just one

oh lol

i originially put 2000 as the first EFI mini engines. I didnt know they came out in 1993.

Also DOWNDRAFT DUH! that makes sense... side draft, downdraft... where did i get TOP DRAFT FROM? :P

if cost didn't matter, I'd be paying a team of experts to build me a custom EFI system that works perfectly... but then I'd probably have a 7 port head as well

a Reece Fish carb would be cool, Vizard talks about IDA webers (yep, downdraft and poking out of the bonnet)

I do like my current 2 x 1.5" carb setup

that is the SU Carby right?

i think mine already has twin SU's. I got a call from John this morning and he said the engine compression on my mini is good - 175 on all cylinders. But it takes me 10 minutes to warm up the mini so that it idles ok. That cant be normal right? Would that problem be more carby related or something else?

Twin su's are very popular in the mini world.

My car also takes a while to warm up and run properly without the choke, but 10mins seems like a long time.

can twin SU's achieve this kind of scenario:

It is a sunday morning. Aliens have attacked. It is apparent that the whole world is in turmoil and everyone around you is getting into their cars and driving away from the massacre. You get into your mini. You start your car but have no time to warm it up. You drive off at full speed cutting through the traffic and avoiding the big independence day type of explosion that hit your neighborhood. You sigh in relief as your car reliably hums along the highway with no signs of it dying at all.
