Re: Engine dies and can't figure out why
Now that I've had a few more minutes to think about this I have a
suggestion. Next time you are there, you could remove the distributer
and take it to someone who has one of those old Sun distributer
analyzers. It takes 1 minute to se

Re: Engine dies and can't figure out why
Sorry, don't know what happened there. My mouse is acting erratically.
It only takes 1 minute to set the timing after removing the
distributer. And for the few dollars it would cost, I would change the
coil (and check the ground wire) because it is probably ready to fail
anyway.

Re: Engine dies and can't figure out why
Glad to know someone else owns a GPW. I have a 1943.
Replacing points and condensor would be a good start. These are just
tune up items for that engine. If you still have the problem then
replace the coil. The system is so simple, not like modern cars with
computers and a bunch of sensors!

Replacing points and condensor would be a good start. These are just
tune up items for that engine. If you still have the problem then
replace the coil. The system is so simple, not like modern cars with
computers and a bunch of sensors!

Re: Engine dies and can't figure out why
Glad to know someone else owns a GPW. I have a 1943.
Replacing points and condensor would be a good start. These are just
tune up items for that engine. If you still have the problem then
replace the coil. The system is so simple, not like modern cars with
computers and a bunch of sensors!

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.
