Thanks for this
@Dizzy. Very useful. As you can see in this video
my vacuum advancer is slipping out as there is nothing to hold it in place. The PO just decided to remove the octane adjustment mechanism off to get distributor in the awkward position. I will be ordering a new distributor or at the very least, finding new octane adjusting dial. Also will is tall new clamp.
If I understand your recommendation, the following is the process.
1/Find TDC of cylinder #1. This is achieved by looking inside spark plug hole to see position in the top “closed” position. Turnover engine until TDC is achieved.
2/Once TDC is identified, make note of seated depth of dizzy - important as too deep will impact function of oil pump.
3/Remove distributor cap and disconnect Porter CDI wires. Make note and mark position of the rotor before removing. It should be pointing at cylinder #1. (The firing order is clockwise 1,5,3,6,2,4). The cap wires need to be routed this way with install.
4/loosen clamp and pull dizzy out and spin counterclockwise so the advancer is now on left as in your photos.
5/ install new octane dial and dizzy clamp.
6/drop dizzy back in making note of depth and the advance as the gears sync a few degrees of angle?
7/tighten clamp install distributor cap with wires attached to the correct firing order (clockwise from #1 cylinder) 1,5,3,6,2,4
