Hi,

Just wanted some advice, We have a 1984 Mini and have removed the carb recently, is it a big task to put a twin carb back on? or a Webber? If it is too much then we will stay with single.

Thanks

Well what engine do you have...........

[scruffy_77]

its a 1 litre

depends what else you plan to do to the engine..

Brother in laws got twins on his 998, and can't say I notice any great difference between how his performs or mine or my sisters which both have standard HS4 carb on.
Actually we are going to swap his twins for a Hif38 this weekend.

As for fitting not that hard, can be a bit fiddly getting linkages together as you fit the carbs, then you need to balance and set them.

go for one su Hif38 carb .. as imo all the other carbs will be over kill on a standard 998 engine

Okay, having had both on a mild 998c (12G295 head, Stage 1 exhuast) allow me to go through the list of pro's and cons.

Single Carb (Hs4, HIF too complex).

Pros -
Easy to maintain.
Parts easy to come by.
Only two major adjustments.
No special tools required.
CHEAP!

Cons-
When they do go wrong, they do so badly or stupidly.
Induction noise can be fierce.
Bit weak at times.
Flow is lower than that of twins (as in air flow).

Twin Carbs (HS2's)

Pros -
Looks awesome.
Good if you like to fettle.
Nice and responsive on the throttle.
Good flow rate (when tweaked).

Cons -
Bloody expensive.
An arse to adjust when one carb is slightly more worn than other.
Choke is VERY stiff (pulling two on one cable).
Needs a good ear.

So, both systems have their advantages. If you just want to drive from A to B on a regular basis then go for single carb. As it will be easyer to fix when it goes wrong. As twin carbs you normally need double the parts.

Twins are good (bow chica bow wow) if you want to have fun. Very responsive and much better to drive with than a single carb but can go SPECTACULARLY wrong. Mine went wrong and killed my car 5 times in one day but I managed to get home (just). So now back to single carb.

cheers for the detailed response mate, and sorry for the delay - been on holiday.
okiedoke, the plan isnt to drive the car daily, just on a sunny weekend... so I am thinking a twin carb is whats needed for me. As its only a small engine I was just trying to think of easy ways to get the most out of the engine and thought this should do the trick, i dont want to go down the road of swapping the engine out etc... I assume with a good air filter/exhaust and twin carb it will pack a bit more punch than normal.

cheers,
Luke
