The permanent magnet starter motor gets its power from the same place any other electric starter gets its power from: the vehicle's battery. It doesn't magically create energy from the molecules of the magnets. Also, I don't think it's a true statement that it's more efficient. As far as I know, PM starters are used because of their light weight and high torque, not because they're efficient.
Just so we're comparing apples and apples, lets look at the equivalent starters produced by Sky-Tec, the leading manufacturer of starter for reciprocating Lycoming aircraft engines. Sky-Tec offers nearly identical starters in both wound-field and permanent magnet versions. Check out the link below. Compare the HT and PM/LS models. The 12 volt versions are rated at the identical horsepower while drawing the same current. With the 24 volt versions, the PM starter has a bit more horsepower (10 percent), but it draws a LOT more current (48 percent!). Conclusion: the permanent magnet starter is no more efficient than an equivalent wound-field starter.

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
