Cars use MAP sensors for their ECU manifold pressure inputs. They don't use vacuum sensors. They want Manifold Absolute Pressure.

Another one is brake disc thickness. Not well known at all. Cleveland has published thickness limits in their manual...

I'd be looking closely at those wing roots and carrythrough on the right side. The forces that dinged that wingtip pile up at the roots...

Neither the Bendix nor Slick manuals give the impulse speed, but in working on many of these things, and working that impulse, I'd guess...

This isn't too uncommon when some idiot services the prop. You don't just put a greasegun on a zerk and pump away.

The impulse doesn't have magnets. The magneto has the magnet, and the impulse simply stops the mag's rotation while the coupling...

A missing stop pin will do it, too. If that pin falls out it can get into the accessory case gearing and trash the engine.

No, that impulse coupling also snaps the mag over rapidly so the magnet and coil can generate enough primary current for a spark at...

I posted that diagram because the free service manuals that used to be on the 'net until recently have been taken down. I suppose Cessna...

Yup. But a lot harder to move around on the ground. Nothing but the towbar and prop. Struts are handy. Make sure the gear system on any...

I've never encounered any diode between the alternator and bus. The alternator already has diodes in it that not only rectify the AC...

Just the P210, I believe. Pressurized, so as few compromises to the cabin sealing as possible.

Not quite. A vacuum gauge rests at zero when there is no vacuum, and when there is vacuum, the reading is giving the differential...

Found the guy who doesn’t know how a hovercraft works.

MAP is the better term. Manifold Absolute Pressure. When the engine is not running you will see the current barometric pressure on the...
