Hey guys, i gotta 92 Chevy Astro van as my winter car and i want to make sure the ignition timing is set correctly. It has the 4.3L CPI (vin W) engine. I know its suppost to be set to 0 degress but i can't see any numbers on the timing tag and don't know where 0 is. can anyone show me a pic of the tag with the numbers or just like tell me the numbers from right to left. thanks...fyi the tag looks like...4 "teeth" and one very deep one on the right.
