Rich at idle, lean at WOT

[shwah]

I run mine in the low 30s fixed timing and it starts fine.

The Autotech power modules do occasionally fail. The simple resistor/potentiometer in line with the CTS works as well, but is more simple/reliable. You can absolutely feel it if you switch it on or off.

Thanks Chris.
Any links that show wiring diagram and parts needed?
And do you think I should install the throttle switches?

There are some diagrams out there, I just don't know the links to them. Techtonics also makes one, that plugs in to the throttle switches for actuation.

I have seen the switches and the brackets for the throttle switches fail, which kills your enrichment and endangers the engine. I finally ditched them before I went to IT Fest a few years ago and just used a dash mounted switch. I found that once up to speed I could just leave it on rich all the time. It does make it too rich at low rpm though, so some a throttle acutated switch that acts at 2/3 - 3/4 throttle is nice.
