Steve, Having never owned or usd a DVG, I found this article online and after
careful consideration, did a copy paste for your benefit. I think the fellow
is spot on in describing the application and results, and I believe this would
work well for your application.

Article:


I have had many requests for the carb jetting used on my stock and slightly
tired '73 2002 motor since I have often waxed lyrical about the smooth
operation at any RPM and the complete absence of deadspots and bog on
acceleration from a stop. So here they are. Credit for these settings goes to
Creighton Demarest.
Primary Jets
Main: 140
Air Corrector: 145
Idle: 60
Secondary Jets
Main: 170
Air Corrector: 175
Idle: 55
In addition, plug the small brass high-speed enrichment orifice in the top
cover of the carb since this extra, coarse fuel supply is not needed with this
jetting. This mod may have solved a problem I had with clouds of black smoke
on WOT. I used a carefully-sized round toothpick to plug the hole. I cut it to
length so that it is held tightly in place when the top cover of the carb was
secured, no epoxy or sealant is necessary.
I have recently found that using 55pri/50sec idle jets works well for me and
may be just a little easier on fuel consumption.
Overall, I have found that fuel consumption has not increased noticeably,
except perhaps from the extra "testing" of throttle response I now do. Effects
on emissions compliance are unknown at this time but I doubt it is very severe
and certainly not likely a problem at idle. Slighlty smaller main jets,
perhaps 130 and 160, would probably bring the loaded CO back in line with
minimal performance loss.
