yea, THAT Switch I wouldnt have.
I believe the FI, at least the later versions were designed to cut out when
the CHTS opens up, when that connection opens up it doesn't just choke, its
like turning the key off...  had this happen with the last one I used
probably 10 years ago.

That's a possibility, but I doubt if that's it. Still, I'll check the 
pressure when I get into it.

Hmmm, I would have thought that it would run, but maybe it gets so 
rich it just can't run. I can check that someday. That's not a big 
difference.

No, it's a 3 position switch, OFF/NORM/(ON), where the (ON) is 
momentary, and NORMAL and ON are different outputs. You're not likely 
to have one. In reality, it's a double pole switch, 2 switches side 
by side with different actions, like this:  

OFF/ON/(ON)
OFF/OFF/(ON)

Yeah, took some effort to find....
