Ok so my plugs keep fouling...so I just took my tank off...and turned on the petcock with the tank off...it rapidly spewed gas from the main fuel connection. If I remember correctly they are notsupposed to do this...I remember reading that they should only let gas through when receiving vacuum from the motor.....regardless the position of the petcock (On. Off. etc.) Correct me if im wrong.

 

yeah nothing should be coming out unless its connected with the vaccum tube, check this thread
