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
