Since Weber is currently out of business or ???? I'm having trouble locating a pair of new 45 DCOEs. A supplier in England (EB Spares) has suggested Dellortos. Is there a downside to the Dellortos? I know my mechanic prefers them, but I want to make sure I'm not limiting myself in some way if I buy them.
Thanks Jim. Do you have an opinion on which carb is "better". It looks like the supply of jets for the Webers is drying up too, so going with Webers just because they are readily available isn't a good reason any more.
All my carbed Alfa experience is with the DCOE so I can't comment on if it, or the DHLA, is better. I've read though that the Dellorto is on par with the Weber and in some cases, like the transition circuit, is even better. The 67 GTV we drove to the Alfa convention this year had Dellortos and I must say I was quite impressed with them.
First I've heard that Weber parts are drying up.
The plant has closed down, some say it declared bankrupcy. The story was it had to do with a labour dispute. My Canadian supplier said he hasn't been able to get anything from them for more than 3 months. Kevin at EB Spares confirmed that he can't get any parts or carbs either.
dellortos have a better air flow than the weber, i have been told for example that a 36 dell will perform close to a 40 weber.
anybody any thoughts?
At wide open throttle I doubt that there is a difference in airflow between the two all things being equal. I've never heard that a Dell 36 will flow more than a Weber 40. At first glance, that seems to defy physics. I've generally heard that Webers are easier to tune, stay in tune better, and have a better float design than the Dells but I have no first-hand knowledge of this. I think either brand would work fine for a street aplication with no discernable air flow or performance advantage by either.

No problems with getting hold of Weber or Dellorto parts. Address and telephone details below. They do ship abroad world wide and know both Weber and Dellorto carburettor specifications etc in huge detail. They have also fabricated precision sprung linkages (certainly for Dellortos) if you need them also. Website www.racecar.co.uk/dellorto. A small but excellent outfit.
