Timing a 1986 corvette
Im going to slightly advance the timing on my car and am wondering if there is anything tricky I should know. I have never timed a car only seen it done. I know that there is black and tan wire going into the brake booster I need to unplug. Do the numbers show up easy when you hit it with the timing gun?
Thanks

Hit it with Brillo or sand paper. If not, the deepest or biggest cut is always the mark which is 0 and go 4 lines over to 8.

I always take a little white out and use it in the slot in the balancer. This will cause the mark to jump out at you when you use the timing light.
Just remember that when you disconect the EST wire and time the car, it will throw a code 44 (I believe that is the code). This code is thrown because the wire was disconnected. Things are fine....just remember to disconnect the battery for a few seconds after you have timed the car and plugged the EST wire back together. ALWAYS disconnect the NEGATIVE cable.
Good luck....a good learning experience.

My personal campaign to prevent stripped battery terminal bolts from disconnecting the battery to reset ECM error codes...
Disconnect THIS connector instead (from the '86 shop manual -- no tools required):
It goes straight to the ECM and nowhere else, so you don't lose your settings on the radio or A/C.
