I know DCOE isn't a weber carb type typically fitted to SBF but I've seen some dual DCOE configurations and it's pretty interesting.
Here's a DCOE question.... My understanding of the various configurations of DCOE (4,8,12,18,151, etc.) is that other than the obvious jetting differences, the primary difference is the placement and sizing of the progression holes drilled in the side of the throat. Is that correct?
The progression holes affect the mixture progression as the butterfly comes off closed/idle to part throttle. Makes no difference at WOT. A DCOE4 will have a different set of sized progression holes than a 151 for example. I've always tried to stick with the OEM reco'd DCOE when fitting these for this reason (alfa, MG, Jag, etc.). Is this correct? Are there other differences in the carb itself across the various numbers?
Thanks
