Dual quad info

The exact numbers of the carbs I don’t remember.
I messed with so many of them and that was so long ago. It may have been an electric choke carb at one point.

It doesn’t matter either way. The choke plate(s) were wired open or removed. In your case, (Canada cold days) an electric choke on at least the rear carb would make for an easy warm up and drive.

As far as netting goes, you’ll need to tune them per engine for best results. It doesn’t matter what it started out as.
