Tuning

Good morning, Dan.
I suggest you buy a new timing light. That is if yours is quite old.
Basically if you remember how to set up a timing light the light flashes every time the plug fires that you put it on. Like plug is typically #1.
With a dial back light you can set when that light flashes so you can set it to “0” when running then dial it back to what you want your timing to be so when your timing is “all in” or the most retarded or advanced it comes up on the balancer as “0”. It is for really good timing and fine tuning. It eliminates a timing tape on the balancer for those procedures.
I suggested you buy a new timing light because old lights the capacitors go bad over time. This can give you false readings. If yours is newer you’re fine. A basic tune up only needs a basic light.

Timing is really simple, so don’t get over welmed. There are a lot of things you can include, but donot need to. Ask on here for a member that may be close to you and see if some one will volunteer to show you in person to refresh your memeory.
Lots of videos on u tube about this subject.
Again it can be easy or complicated. Go slow and understand each step and you will be fine.
