The solenoid will open fine when there is no pressure to it. But once I put pressure to it and try and open it, it won't open???? I've had major problems with the nitrous not flowing well... It was a clogged filter... But once I unclogged the filter, it won't open when the bottles on???? I know that the solenoid is made so the pressure holds it closed, but it opens when no pressure, not when there is... Any suggestions????????? Pleeeease help! Nick P.S. the kit is a cheater carb kit.
