Locating dimple on timing gear

[Patrick L.]

Set point opening [ .018-.022"/ preferred .020"]
Locate TDC with timing pin as you did, good.
Then use continuity meter or test light to set point opening by loosening and turning rotor. Make sure all shaft back-lash is removed when doing this.
It is important to do these procedures in correct order.

Also make sure the spark advance lever is fully retarded (up) when setting the timing/points.

If there's any chance the engine will be started the engine with the crank handle - ever, I time the engine with the lever a couple of notches down. I run a high compresssion (5.5:1) head so I don't need as much advance as Henry gave us so the slightly less advance this gives me is not a worry.
By doing this, when the lever is all the way up, the spark fires slightly AFTER TDC so there is NO chance of the crank handle kicking back.
Just my safety tip!

Ooopps, senior moment.
