kelloggs - 27/4/08 at 12:56 PM

I have the opportunity of acquireing a pair of dellorto 45 carbs they were originally fitted to a 2lt pinto previouse owner had great difficulty getting them set up & running, after spending a lot of money cleaning and getting new jets had no success, the new jets fitted for the pinto were;-
main 142
idle 60
air 177.5
emul 7772.7
pump 38
original jets were;-
main 160
idle 50
air 230
emul 7772.8
pump 42
as anyone had any success with running dellorto 45 on a 1600 crossflow. Also were can I obtain a inlet manifold for said item

I once had twin 45 dellortos and went through the same thing, refurb/re-jetting etc......mystery.

Even though they are meat to be a little more powerful and an improvement over the webber design I would avoid future use unless they were brand spanking new!

But thats just my experience!

I think Burton Power do the manifolds brand new. They also appear second hand on Ebay fairly regularly.

Is your engine standard or modified? They may be a bit overkill on a standard 1600 crossflow.

Agreed, the 135bhp Caterham Supersprint managed on 40DCOEs, so going for 45's with a lower state of tune is only going to hurt driveability.

All depends on what size venturi have been fitted, my old crossflow ran fine on 45s.

i have a pair of dellorto 45's on my crossflow allthough it is running 1600cc it's at quite a high state of tune for a crossflow

Thanks for all the replies, work carried out on engine was complete re-bore, head skimmed, lead free seats fitted, re-grind crank, new cam followers, fast road camshaft, fly wheel faced and lightened. have not yet fitted electronic ignition. Any suggestions on what size jets for 1600 crossflow

I have a set of weber 40 DCOEs with a cross flow manifold that I'm not going to be using . Carbs would need an overhaul and rejetting , open to offers

They look nice, but as already mentioned I would go for bike carbs or throttle bodys as setting them up is expensive and there never very economical.
