...NoDOHC thanks for your feedback always a pleasure to hear from you....the BAC is bad i believe, the plunger is not moving...just tested it..the BAC was not plugged in either at the time and i tried it plugged up and not plugged up same rpm hunting...waiting to get the block off plates and gaskets now.
