Timing an 86 pickup

Is there a wire that that advances the timing that needs to be un-plugged before timing an 86 305? If so would someone please tell me where it is? Thanks

Far as I know, you just disconnect and plug the vacuum advance at the carb, then reconnect after your timing is done.

Thanks Bill.

One more question please. Which pointer on the timing indicator is 4 degrees before TDC? I can't clean the indicator unless I remove the water. Does anyone have a picture of a clean timing indicator?

Each mark on the timing tab is 2 degrees.

There’s a pic in here of yours.
