Yeah mines the MSX3, the one right below yours. True, get it dialed in and the change. I know Maddart had to change couldn't get his reluctor ring mod to the distributer to run right so upgraded but never ran to again since he sold it to me, so this will be interesting.
Yours is Megasquirt right Matt? I may eventually go to coil-near-plug and crank-trigger wheel to get the full timing feature set of the MS3 but need to start out with what I’ve got.
