Timing with the TRI SPARK

Hello to all near and far.... I have just gone through the long process of making my own wire harness for my 70 Commando. I've also installed a SPARX alternator and a TRI SPARK ignition. When I installed the TRI SPARK I did not advance the timing to 31 degrees (if that's even the number)- I just put installed it and went on with my wiring (one thing at a time). Now that I'm finished with the wiring, I will need to time it correctly.

Can anyone step me through how to time it correctly with it static ? I'm sure it's simple, but since I just put months of work into wiring and learning I really would like to be sure.

-Do I need to rotate the wheel and dial it into a specific number (if so what is that number) ? OR - Can I just turn the TRI SPARK plate and read it on the TRI SPARK (if so, what is the degree number)?

Any help is very much appreciated.

Cheers!

Obviously you need to follow the Tri-Spark set up instructions, and set the crank to the standard 28 degrees BTDC F/A figure, using the alternator rotor ignition scale and the correct scribed line on the rotor.

Apparently Steve Kelly told one of our members that "some" Commando engines may benefit from being set to 31 deg. BTDC?

I set my own Commando's Tri-Spark to 28 degrees BTDC.

Mine is also set at 28 degrees. The static LED indicator gets it close, but you still need to dial it in with a strobe at 4000 RPM.

As for wiring, consider installing an inline fuse in the power wire to the ignition module. Nortons are famous for chafing the wires that go through the timing cover. One of those wires is now battery power, and shorting to the engine will do more than kill spark. A 3 amp fuse is plenty. Carry spares.
