I've asked this before but I need to ask again. How the heck do I set my timing on my 89 Burb?? Pictures would REALLY help. I've looked all over for the plug people say you have to disconnect, the only thing I found is a plug thats on the dist or coil(I forget right now) and isn't plugged into anything. I had a small engine fire tonight that resulted thanks to bad timing(backfire) and a small fuel leak I didn't realize was there.
