Guy's
Does anyone have a conversion chart for true venturi sizes.
Example- 0.250" restrictor what size bore for a true venturi?
Thanks
Paul

Calculate the area minus the spraybar and you have it.

Paul, this is from a chart I've used over the years, based on a ST NVA (0.157 dia.)...hope this helps:

Venturi .126 = Restrictor .250
.148 = .270
.159 = .280
.170 = .290
.181 = .300
.192 = .310
