I'm trying to pull the distributor out of my BBF but it won't seem to come out. I pulled the one bolt that holds it down. It will twist but it won't come out. Am I missing something?? As most of yall know I'm new to gas engines. Also, I want to test the oil pump. Once I get the dist. out, all I have to do is get the attachment to put on a drill and stick it down there right? Thanks in advance.
