[Farmall] F12 Timing

[John Hall]

I can't see how it could trip off impulse fast enough to miss the next pawl 
unless something is worn/broke/bent. I'm not certain at what RPM the mag has 
to turn before it quits impulsing but when I run them on my Allen tester you 
can't really count the clicks as fast as the mag is impulsing.

 It's going to be interesting to see what is the matter with yours. I've 
rebuilt a few F-4's and only ran into the one bad impulse that I mentioned 
earlier.
