How much Vac should I have? 700 88

posted by  someone claiming to be Ryan Pirtle on  Wed May 2 06:13 CST 2001 [RELATED]

I have a 1988 b230ft motor in my 740 and I am reading about 9 Hg?? of vacume at idle. It runs real rough at idle so I am thinking that is too low. What should it be at? Could a bad head gasket be the problem?
