So, I take it you have an EST distributor and a carbed engine, is that correct?

4.3 timing wire.jpgimg_0830.jpgimg_0831.jpg
Went to the junk yard & got the wire off a 93 astro van.Little bit of soldering and bam.Timing is set.
Hope this help someone out there.testlead.jpg
Set Timing as follows:
1. Start and run the engine until it reaches proper operating temperature.
2. Connect timing light to #1 spark plug wire.
3. Remove the blind plug (1) and install timing connector p/n 885163 onto distributor. Attach the alligator clip lead to a B+ source.

NOTE:
The Alligator clip lead of the Initial Timing Connector must never be connected to a B+ source until after engine is started. This is necessary to avoid damage to the electronics of the ignition system.
When the B+ source is connected, the engine may reduce RPM. If engine stalls and must be restarted the lead to the B+ source must be disconnected.
