So how can I tell if I have to much or to little?

Don't worry, she'll let you know if you have too much or too little.

Try a little more advance at a time until you get detonation, then back off. That usually gets the performance and mileage optimized; usually hurts emissions which are likely not an issue there in R-Kansas.

I dont' know if I have actually ever heard detonation...?...I've heard the descriptions of it but don't know if I could pinpoint it safely...

Yep...no emission checks here in "R-Kansas"

Like marbles rattling around in a can - usually at when you open the throttle up a bit a mid or higher rpm.

You think I can hear it over my exhaust...or that will just make it harder...I guess it depends on how advanced it is making the "marbles" louder

So does that popping on my car possibly mean I don't have enough timing? It is at 16*...

I hope it is a free problem (timing) and not an expense problem (replacing injectors)...the weird thing is that I noticed it that one time?...

I read this somewhere: Can you get it on in the upper rpm (maybe around 5k for example) under load at WOT and shut off the car (at that rpm )and pull a plug to see if it is lean...? After coasting to a stop? Would that be good to shut it off after being revved...doesn't sound good but was suggested on here as a quick way to find out if I'm running lean (possible timing)...

Wouldn't the heat in the combustion chamber ruin that reading on the spark plug or would it "stick"?
