ideal carb set up for mugello 186

[cit205]

I've got an Li with a mugello 186 ,indian big bore ,indian gp box ,and 22mm spaco delorto ,sort of a touring set up which it does ok at ,apart from the fact it doesn't seem to like 22mm carbs .

It's been running this set up for a few years and is actually my mrs's scooter hence why i've left it so long to decide i've had enough of 22 carbs on it Tried 4 now,jetex x 3 and now a spaco, but the trouble is it floods up too easily and dare i say it being a woman she doesnt have the knack of predicting when it's going to mess up, i.e she'll grab too much of a handful (ooer :anbrgin; ) and it will flood, and then she'll be at the traffic lights for ten minutes trying to start it. Or if she doesn't cut the fuel long enough before stopping the engine ,it won't start for ages either.
Needless to say,i've tried all the jetting options to eliminate any jetting issues, and i'm not sure it's running that efficiently with the 22 carbs anyway.
So the question is ,in anyones experience what is a better set up, have heard 25mm through the airbox ,or remote somewhere,and what carb, and does anyone do a complete kit i.e carb,cables,manifold,filter/hose set up?
Cheers

What about a 30 mil delorto? You can pick them up new for about fifty quid from the Fatherland. People have been using them for years, and there's heaps of jetting advice available - not that they're difficult to set up. Manifolds are easy to come by, and all the cabling is a piece of pi ss.
If set up right, it shouldn't give a moment's trouble.
And it should be more fuel economic too, being new, and set up properly.

that's a point..i've got an unused 28 phbh in the shed off a vespa ,suppose that's worth looking into.
i just wanted to keep it all small and tidy and through the airbox

To be fair, 28 is pretty small...

Well ,not when compared to 22 :bigsm:

stick the 28 delly on with a foam filter. it"ll run topper on the muggello.

6 of us run/rally with 28mil Dells (open) on Mug186 with A/F big bore.

I've got a couple of scoots with Mugello 186s. One uses a Mikuni TM24 on a 25mm phbl inlet manifold and through the airbox.
It gives an excellent ride with a clubman, pulls 1:5 gearing and does around 80 miles for 5l of fuel
The other has a JL3 fitted, again with a TM24 but this time using a foam filter. This is a different experience, noticable power band, 1:5.2 gearing and does about 50 for 5l of fuel.
I've had a 28mm phbh on the one above and there wasn't too much difference, other than they can be tricky at low revs (loads of 4 stroking).

Oh, and Martin at JustLambretta should be able to supply all the bits you'll need.

Thanks for the advice everybody, i've ordered a mikuni tm24 kit in the end ,after weighing things up i'm impressed with what i keep hearing about them
