I've done a LOT of governor tuning with TH350s and 400s. What you do is, get the shift points close with the weights and then select springs to set shift spacing and fine tune the shift points. ...

With MSD, I assume it's a CYA thing. If the coil is upright and does leak, it's going to run longer before the air bubble inside gets large enough to cause failure. Mounted upside down, a leak will...

Start with about a 100 shot, it's just enough to really feel the hit. It takes work to clean up the tune, and you'll want to step up before you get the 75 shot to run clean.
