Re: [Chevelle-list] vacuum advance hits manifold

Sears has a timing light that does both total and initial timing for about $65.  Nice tool.  To confuse you more.  I just solved some similar problems with my BB w/ mechanical advance.  After you check the timing and it is right - and if you still have problems -  make sure your carb is functioning properly and fuel pressure is adequate.    I ended up spending days playing with both a mechanical and vacuum distributor thinking that was my source of backfire and engine miss when it really was fuel related.  I rebuilt the fuel pump, and changed the pressure regulator and the 10 year old Edelbrock 750 AFB. It runs great now.   Larry Williams 65SS  427 BB ----- Original Message ----- From: John Nasta To: The Chevelle Mailing List Sent: Monday, May 02, 2005 10:20 AM Subject: RE: [Chevelle-list] vacuum advance hits manifold Thanks Wayne.
