Re: Engine dies and can't figure out why
I was thinking and remembering one car that up and died when hot. It

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.... |
