How about electronic ignition? Anyone running that, too.

A front governor is driven from a location near the crankshaft's fundamental vibratory node, which means it would see very little vibratory amplitude even if the crank was doing the Chubby Checker

For the youngsters who may be present: https://www.youtube.com/watch?v=pHGXwQeUk7M

Duh.....wrong!

That's what I get for writing without thinking. The governor is driven off the forward end of the camshaft, which, in terms of torsional vibration, is likely to be a very active location.

Anybody know off hand what the ratio is for the governor this way I could look for it on my spectrum analysis runs.

I am currently in the middle of swapping the MT for the Hartzell and this is not proving to be easy. The control arm location is totally different and it looks like I will be talking to Hartzell in the morning.

Does anyone have information on the 4th failure that has been mentioned? Was it also a C4B5?
