Patient: 1988 5kq Intermittant start

[John Gourley]

The possibility of it being the ignition switch has been on my mind.  I
realize they can wear out....used to replace lots of them back in my days
working on the aircooled VW's.
For some reason, in my case, I don't think it is the switch, but will not
rule out that idea

thanks!
