Engine dies and can't figure out why

Re: Engine dies and can't figure out why
I was thinking and remembering one car that up and died when hot. It
was hard to figure until I checked the points. The fiber bumper had
worn down so the gap was really small when cold. When hot, parts
expanded and closed the gap.

Re: Engine dies and can't figure out why
Thanks for all the suggestions!
The jeep has been upgraded to 12v, so I ordered a new Borg/Warner coil
from http://www.willysjeepparts.com/ . I also have a new condenser and
points from when I got the tune-up kit and replaced the distributor cap
a few months ago.
I should be able to install the three parts in a couple of weeks and
I'll report back if it did the trick....

I'll report back if it did the trick....
The jeep has been upgraded to 12v, so I ordered a new Borg/Warner coil
from http://www.willysjeepparts.com/ . I also have a new condenser and
points from when I got the tune-up kit and replaced the distributor cap
a few months ago.
I should be able to install the three parts in a couple of weeks and
I'll report back if it did the trick....
