i hadn't thought to check the starter, actually. it
seemed like it was turning the motor just fine, but
after maybe four or five shots at it, it cashed out
the battery. i figured it was probably a fault of the
battery which looks like it's older than dirt [the car
hasn't been driven all that much in the last ten
years]. the starter looks like original equipment, so
even though it's only got 52k on the clock, it's still
35 years old.

does anyone have a ballpark figure of how much a stock
mopar starter should pull when cranking (10:1 comp,
hot)?

could it be that maybe the car's fine, but it's the
fault of the rotten low-octane unleaded mtbe-tainted
swill they call gas these days? once upon a time,
someone on the fullsize jeep list i'm on had mentioned
that modern gasoline was more susceptible to
vaporization than the stuff they were making back in
the fifties and sixties. i think the rationale was
something like lower boiling points did something to
help lower sulfur emissions, and because cars made
today have sealed high pressure fuel systems for
injection (40-50 psi) it's not as much of an issue on
hot days like it is for those of us still running
carbs and mechanical pumps (5-7 psi).
