Re: [Chevelle-list] timing questions

Dan:     What carb are you running? My edelbrock has two vacuum ports, one designed for the older distributors that assume there is no vacuum at idle, and another port that gives a small amount of vacuum even at idle. The port you use depends on how the distributor is set up.   Tom Tomlinson '71 Malibu ----- Original Message ----- From: Dan McIntosh To: [EMAIL PROTECTED] Sent: Sunday, April 18, 2004 3:06 PM Subject: [Chevelle-list] timing questions Hi all, I set my timing yesterday on my motor with the vacuum advance disconnected.. I set it at 8� BTDC, and it runs great.....until I hook up the vacuum advance again, at which point it starts wanting to stall right off idle, and backfiring out of the exhaust..   any ideas what my problem is? The dist. is a brand new HEI unit...   thanks   Dan McIntosh Street Metal Fabrications Pavement Scraping 1964 Impala S.S. http://www.lowriderimpala.com
