Re: [Chevelle-list] timing questions

If it's the adjustable vacuum advance,, most cans be adjusted with a Allen wrench. Do you have a dial back timing light ? there the cat's meowew for setting ignition curves. or for cheep get a MrGasket or summit  degreed damper tape,, your regular timing light  can read the trimming through your RPM range.   Wayne ----- Original Message ----- From: Dan McIntosh To: The Chevelle Mailing List Sent: Sunday, April 18, 2004 6:12 PM Subject: Re: [Chevelle-list] timing questions yes, I capped off the vacuum line while setting the timing.. the dist. is an aftermarket no name HEI. I believe it has an adjustable vacuum advance.. Its almost like the advance is coming on to soon... anyone know how I can test that?   thanks   Dan McIntosh Street Metal Fabrications Pavement Scraping 1964 Impala S.S. http://www.lowriderimpala.com ----- Original Message ----- From: Mike Holleman To: The Chevelle Mailing List Sent: Sunday, April 18, 2004 5:38 PM Subject: Re: [Chevelle-list] timing questions Dan, Are you blocking off the vacuum while you are setting your timing? Maybe plugging is a better word. If not your timing will change substancially once hooked back to the dist. Just a thought.

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
