A: If you are running a Carter BBD with feedback carb, the timing will self 
adjust as long as the knock sensor functions unless it's had the Nutter 
Bypass done.

Timing.

Retarded.

Me I mean.

On the road trip to Santa Fe last week I'd retarded it on the
side-of-the-road "a few degrees" to deal with the crap gas I was
buying.
A "few" turned out to be 10. Can't beat actual measurement!
Didn't
pinging though, uhuh.

The 87-93 Clymer's Jeep 258 book I have, says the carburetted
motor
wants 9 - 11 btdc static timing. I never bothered to look in the
newer
books before [but wanted to double-check the new-fangled timing
mark
setup], I assumed (ahem) it would be the same as older models
(usually 4
- 6btdc). Wrong again.

I set it to 8btdc. I'll find out tomorrow on the drive to Irvine
(45 mi.
each way). I hope I'm not wrong a third time.
