Got a mate whos selling mini parts and one of these is the 45DCOE carb.
Question is, would this benefit my 1275 engine? Probably be coupled with stage 3 head, wilder cam and high lift rockers.
The 45 DCOE is second hand, but in good order, so thought it was a good deal at £270 for twins.
Any help much appreciated.

Edited to add: after doing all this to the engine, will there be a noticeable difference in power?

Some people love 'em and some dislike 'em.
You certainly can gain a bit at the top end and they do hold their tune better, once accurately set-up.
They are more noisy and tend to use a bit more fuel(that's a personal observation). You need a good cam, at least a 286, to benefit, otherwise stick with SU's.
I did drive a rally car with a 649, a Weber 45DCOE, LSD and a 4.1 finqal drive. It went like the proverbila, but was horrible on twisty stuff and on ordinary roads. After the owner drove mine he went to a 286 and twin 1.5 H4's and was quicker overall, but slower in a straight line from a standing start.
I think it's personal choice.

Cheers for the help.
Are 286 cams a bit to wild for normal road use (nothing below 3000 sort of thing) or do you only need to slightly adapt your driving?

They are a bit 'cammy' for normal road use, especially with a standard box and high diff ratio.
However, there is not really any npoint in fitting a 45DCOE unless you go to such a cam as you won't gain anything.

I probably could adapt, as I like every journey to be exciting, but probably it will be better to go SUs as I'm not going to go to a ballistic level of tune.

You'll struggle to fit a webber on a decent manifold. Normally you have to cut a hole in the bulk head and slot in a suitable box, but you might get away with removing the speedo plate. The DCOE is a single twin choke carb, unless your mate has a pair of splits. A new carb is less than £300 but thats without linkage, manifold or filters.
