Hi Rich,
You could try this business in Auckland, New Zealand - I have found them very good to deal with.

Good luck.

Greetings and salutation from the great white north. I thought this might be a good place to start.
Well I use to be a 1200 racer a very long time ago and still have thoughts of finding one in fair shape which I could resurect here in Ontario; but no luck yet.

Anyway I thought since you guys have been using DCOE on a regular basis may be you could help; I need 1 single aux venturi for a 48mm SK Race carb, dropped one and it's history, I would'nt use it on granny's car.
TWM no longer carries these...at least for a decade.
By chance would any one have access to one I could buy??

FYI: I have the masters to do the old Electramotive race cams at my shop...-1 and -2. we charge $130.00 Canadian which is approx. $125 AUS; just incase anyone was interested.

Cheers Richard
