To everybody but Kevin especialy I guess since he is running one of those with great success.

What is the rundown on Delorto carbs, how do they compare to Weber? Is 45 the one to get for the mini, what about the 40?

Are they any particular series to look for (like the 45DCOE 13 in the Webers)?

Whats the engine \ box wear once you get one of those?

Cheers.

as i understand a 40 is good for smaller bore engines while a 45 is best suited for larger bores (I could be completley wrong tho...)

David Vizard states in 'Modifying your mini' that the Dellorto works slightly better then a webber when one is used and that webbers slightly out do dellortos in a split set up.

sorry i can't be more helpful, these carbs seem to be the new craze here on ausmini expecially, so someone will be able to help im sure.

I've just gotten hold of a set of 40s myself, cant wait to try one of em out

I like Dellortos, but parts are harder to get.
Mine is a 45DHLA, dunno what it's off- was on the car when bought.

Most I've seen lately are 40DHLAs off Alfas with 33mm chokes.
I have 2 of these, so far I've jetted one as per Des Hammill for our 1132 Clubbie but not run it yet. Des says the pre-emission ones are better but they are all scarce now. The emission carbs have an idle bypass circuit and more progression holes, similar to Weber.
For competition most people close off the idle bypass by screwing the adjusters in.

I recommend anybody running a Weber or Dellorto should buy Des Hammill's book- "How to build and power tune Weber & Dellorto", available from www.pitstop.net.au and elsewhere. It has a wealth of info and explains it all well. I have a few other Weber & Dellorto books, but this one kills them.

I've run a 45DHLA for 9 years on a 1310, seen no unusual engine or gearbox wear. `Bore washing' you read about won't happen unless it's poorly jetted.

<edit> Just don't pay silly money for these things. I've seen a S/H 40DCOE on Redline manifold going for $700 or so... sheesh!
Same manifold is worth about $120 new at Mini Classic.

i got mine from a swap meet for $30 , it was aparently off a 1200 corolla, so should be jetted spot on for a 1275

Compared to Webers, Dell'ortos have more air flow, and finer fuel atomisation. This makes them usually better for the road, as they are more fuel efficient. However, A Series motors don't necessarily like fine fuel atomisation, which means often the Weber wins on outright performance.

45DHLA Dell'ortos would only be required on hotter motors. A standard 1275 would probably work best on a 40DHLA. As a matter of fact, on all choke sizes below 36mm the 40DHLA flows
more than the 45! Thus, don't waste your time on a 45DHLA unless your engine really needs it (ie require chokes 36mm+)

I got a Dell'orto basically coz the price was right. However, I prefer them over Webers coz they are often better for road use, and IMHO don't have as big a risk of catching fire as do the webers, but carry a fire extinguisher anyway

ausmini4u- 1200 corrola engines are a fair bit different to an a series 1275... dont be surprised if your carb isn't jetted right. Camshaft duration seems to change this a fair bit. When i got my weber the car ran like a dog with stock camshaft and the jetting... i fitted a mild road cam and it was almost spot on. from memory only the air correctors were wrong.

According to Des Hammill's book, 34mm is the max choke size that works properly on a 40. It also happens to work well on a 45.
Yes a 40 will flow (slightly) more air with a 34 choke than a 45 does, but it gives less power...
Any 1275 above stock should really be wearing a 45, IMO.
"40s are great on a 1098". Hey, I'm a poet and I dunno it!

I'm running 34mm chokes in the 45 now, I'm about to stick some 36s in. If not better they will come out quick smart. Graham Russell reckons 34s are best for the street.

BTW all parts are available from www.dellorto.co.uk and cheaper than here..

hey i dont mean to hijack this thread or anything......but does anyone know what carbs were used on a fiat 124? they use a twin carb set up but i cant tell if they're webbers or delortos or what size they are

can anyone tell me how to tell the difference?

kev could tell u bout the fiat, dellortos have a large culincerical choke mechansim sticking out the top of the carb while webers dont, dellortos say on the top
dellorto italy anyway

yeah i figured they'd have something like that written on them hey i havent had a chance to check them out properly yet......just thought i'd ask if anyone knew anything about them

i was thinking since its a twin set up and they look like 40's (im basing this on the fact that they dont look as big as the 45 webbers ive seen in the past, so i could be wrong) i could keep one for the 1098 when i finally get around to rebuilding it and could flog the other one to cover some of the costs......

I've always found the big brass dome and wing nut on the top to be the tell-tale of a Weber. Dell'ortos have a plastic jet top (I like the brass more, but can't complain).

Ausminis4u - My Dell'orto came off a tweaked 1098 with a ported 202 head. The jetting is close on my 1098 with stock head (the exhaust system is even exactly the same - ie from the same car), however it isn't spot on (driveable but the progression circuit needs tweaking). The jetting should be closer when I buy the ported head as well, but when I put my mild cam in it might throw it a bit So don't expect the jetting to be right, especially if the corolla had another carb sitting next to it. What jets has it got at the moment?

Cheers,
Anto.

Hey, I'm an ex-Fiat 124 coupe nut.. (shhh, don't tell anybody..)
But the Italian Love Affair is over now.

124BC had twin 40IDA Webers or Solex equivalents.
Nice carbs if you got 4 intake ports. But they would stick thru the bonnet on a Mini, and for big power they are too small.
A Fiat 124BC motor with 1608cc, 80mm bore and 80mm stroke, twin overhead cams and these carbs only made 110HP. I think my Mini is around the same, or more....

Pretty looking head though. I still got one, but it's a bit big for the Mini block...

yeha a mate of my little bro has a 124 coupe thats just been sitting in his driveway for ages and i noticed the carbs sitting there on the head today........

i was mostly thinking of how one would go on a hot 1098 doc? or would something like twin su's be better for that?

and yeah the head looked pretty hot from what i saw..............surely you could work some of your magic and get it to fit!!

Easier to get the Fiat block to fit on the Mini gearbox... on second thoughts that's not easy either.
Do what a guy in UK did- get a Lancia Beta 2.0L motor (same as later Fiat) and the 5 speed gearbox too...

doc...i cant tell the difference between dellortos and webbers....i tihnk the lancia box and donk might be abit beyond me atm
