I was driving my 1983.5 vanagon 1.9L after changing the antifreeze, it is starting to look like winter down here.  I was getting it in second gear, and it semed like the ignition cut out, similar to other vehicles I have driven when the rev limiter is hit.  

I looked at the rotor, and it did not seem like the aircooled rev limit type I rarely see on anything anymore.

It only did it at high RPM and I never tried to rev up the other gears, so do these vehicles have a built in rev limiter, or do I need to start troubleshooting a high speed miss?  

Thanks in advance
