I would like to set the idle up on my 78. Since no carb, I'm not sure of what to adjust. I've tried tightening up the accelerator cable with the adjusting nut, but no deal. Where can I find the Idle air adjust screw, if it has one. It starts just fine and warms up at a high idle, I'm assuming the butterfly valve eventually closes since it will idle down to a mere Bub bub then stall out. I have the John Muir book, but it doesn't seem to have a good diagram of the FI setup to show me where to adjust. Any suggestions or pictures on how the adjust the idle on the FI setup would be greatly appreciated.
