Is this a problem with ignition timing?
A while back, I started a thread about my TII cranking like the spark wires were mixed up, and the car wouldn't start.
Well, it turns out that one of the primary injectors was bad and that was what kept it from starting.
Since then, I've fixed a bunch of stuff and begun tuning the LTX12. Now, it starts easily and idles smoothly at 850rpm.
This may not be a problem, but I'd appreciate input from ones who are more experienced with standalone (especially microtech) systems:
Most times, while cranking, the engine will chug just before the ignition catches on and it starts. As before, it sounds to me like the timing is screwy, and somehow the spark is firing early in the compression stroke.
I've confirmed that timing is correct (have re-installed the CAS per the manual just to make sure), and once started it 'purrs like a kitten'. Here is a link to what it sounds like. The first startup is what I think it should sound like all the time, the others present the 'chug' just before it catches.

All these examples are different times starting it up over the course of about 10 minutes or so.
So, whadya think? Is this normal, or do I have some kind of gremlin still lurking around?
Thanks!

That seemed to help some, but the weird reaction during crank had me concerned about what might be happening at other operating levels.
I appreciate the clarification.
