Re: what did you do to your motorized bicycle today?
Roger I don't know if this will help, on my cns2 the short tube that goes to the filter base was allowing fuel to be vacuumed from the bowl. Mine has only one tube, I removed the tube and plugged the hole in the back plate then used a weed Wacker in tank filter as a vent. Anytime air flow has to change direction like the 90° filter it slow down the flow, the same as it does in HVAC. Yours could be creating more vacuum and drawing fuel from the bowl, mine did what you are saying and thats what I found.
Your results may not be the same,Greg
