Guys,
Am I right in thinking this might be an issue with secondaries opening too early maybe?
It is unlikely if it happens right as you blip the throttle. Does it happen if you are low speed cruising and you give the throttle a quick stab to half throttle?
If so, it is likely lean idle and transition circuits in the carb. It is very popular to increase the squirter size to fix this problem, but in my experience it usually just masks the true issue.
As mentioned float level and opening vacuum of the PV should be checked
